Instructions are indicated by arrows ( ). Always carry out instructions one after the other in the sequence described. Expressions in quotation marks generally indicate a control element on the device (switches or labels) or on its user interface (buttons, menu items). Paragraphs in italics provide information on basic principles, special features and efficient procedures as well as general recommendations. 8
Chapter 2: Connection and Login The configuration of the device is carried out with a PC and web browser over the Local Area Network (LAN). Alternatively, the PC can be connected directly to the device via an Ethernet crossover cable (for devices which are powered with Power-over-Ethernet, a PoE injector is additionally required). Note that the configuration of the device must always be carried out with a web browser over an IPbased network, even if you want to operate the hybrid camera solely as an analog camera later on. 2.1 System Requirements To configure the device with live video display and live audio output, the client PC must meet the following minimum system requirements: Minimum System Requirements Operating system (OS) Microsoft *) Windows *) XP Windows Vista *) Windows 7 (each with latest service pack) Processor (CPU) 3 GHz Intel *) Pentium *) 4 AMD *) Athlon *) 64 3400+ or faster (or equivalent) Random access memory (RAM) Graphics card Sound Ethernet Web browser Software 1 GB (Windows XP) 2 GB (Windows Vista, Windows 7) DirectX *) 9.0 or 10.0 compatible 64 MB of graphics memory (128 MB or higher recommended) Sound card or on-board sound chip (min. 16 bit) 100 Mbps Microsoft Internet Explorer *) (latest version) Adobe *) Flash *) Player (latest version) JavaScript *) enabled Microsoft ActiveX *) enabled Dallmeier Live Video ActiveX (latest version) 9
Note that a more powerful client PC is required if several devices are configured with live video display (and/ or live audio output) simultaneously. a DirectX compatible graphics card and the Dallmeier Live Video ActiveX are not required for the configuration without live video display or live audio output. the latest Dallmeier Live Video ActiveX can be directly downloaded from the device or from. the latest Dallmeier Live Video ActiveX can be automatically downloaded from the Internet after the connection to the device is established (only with the web browser Microsoft Internet Explorer and if it is not already installed). the configuration without live video display and without live audio output can theoretically be carried out with any operating system and web browser. However, the configuration always requires the Adobe Flash Player. Always install the latest version of the Dallmeier Live Video ActiveX after the connection to the device is established in order to obtain the optimal system performance. Information on downloading the Dallmeier Live Video ActiveX directly from the device can be found in the section Downloads on page 92. 10
2.2 Connection The factory default IP address of the device is: 192.168.2.28 Ensure that the PC/web browser can establish a connection to the device via Ethernet. Start the web browser. Enter the IP address of the device into the address bar of the web browser. Confirm the input. The connection to the device is established. The graphical user interface (GUI) of the live mode is displayed: A B C D E F G H Fig. 2-1: Live mode with adjustable video resolution A B C D Hide/show title bar Switch between live and configuration mode Live video Connection method (UDP or TCP) E F G H Adjust video resolution Audio On/Off (live audio) IP address of the device Log out of configuration mode 11
Note the following explanations. Hide the title bar (A) if required. Change the connection method (D) if required. Adjust the live video resolution (E) if required. Enable the live audio output (F) if required. The Connection method does not affect the Streaming function of the device (see section Streaming on page 33). The video resolution setting mentioned above only affects the display of the live video in the web browser, and is not related to the encoder settings. Live audio is only available for logged-in (authenticated) users or user groups. In addition, the audio encoding must be enabled (see section Audio In on page 65). Connection Method If the network connection to the device is established via a router with NAT (Network Address Translation) enabled, the live video may not be displayed in the web browser. In this case, two solutions are available: The router has to be configured for a correct address translation of the incoming UDP data packets sent by the device. The User Datagram Protocol (UDP) is by default used by the streaming function of the device. An easier solution is to select TCP from the Connection method drop-down list. The device then switches the protocol of the streaming function to the Transmission Control Protocol (TCP). To receive the TCP data packets, the following ports on the client side must be open: Port 30000 for the DaVid Protocol 1) Port 80 for the Hypertext Transfer Protocol (HTTP) Note that during data transmissions over TCP usually no packet loss (lack of images) occurs. short-term peaks in network traffic may occur. low delays may occur. 1) Dallmeier Video Protocol 12
2.3 Login The graphical user interface of the configuration mode is displayed for authenticated and authorized users only. The factory default admin password is: 3 NOTICE Risk of access and misuse by unauthorized users Change the factory default admin password as soon as possible (see section Group Login on page 21). Click CONFIG in the user interface of the live mode. The login dialog is displayed: Fig. 2-2 Enter the User name (Default: admin) if required. Enter the Password (Default: 3). Confirm with OK. 13

Fig. 3-1 Select the required Language. Clear (uncheck) the Show live video (ActiveX) in WebConfig check box if network bottlenecks occur or your system is overloaded. Clear (uncheck) the Use DirectX for video in Lens control dialog check box if the live video in the Lens Control dialog turns black (or rather is not displayed) at 8 magnification. Further information on the Lens Control can be found in the following chapters: Lens Control (Remote Back Focus Control) on page 88 Lens Control (Motor-Driven P-Iris Lens) on page 90 Clear (uncheck) the LED signal check box if you want to deactivate the LAN LED signal. Further information on the LAN LED signal can be found in the chapter LAN LED on page 102. Confirm with OK. 15
3.2 System Time The system time can be set manually or synchronized with a UTC time server. In both cases, however, the time zone must be set first. Open the Time settings dialog via Common Settings > Time.... Click the Time zone tab. Fig. 3-2 Select the Time zone. Confirm with OK. 3.2.1 Manual Configuration Note that manual configuration is not possible if the UTC time server synchronization is activated (see section Time Server on page 17). Click the Date/Time tab. Fig. 3-3 Set the Date and Time. Confirm with OK. 16
3.2.2 Time Server Note that the specified UTC time server must be constantly accessible over the network. Click the Time server tab. Fig. 3-4 Enter the IP address of the UTC time server. Select (check) the Use time server check box if you want to activate the synchronization with the specified UTC time server. Confirm with OK. If using a host name instead of an IP address, you must ensure that the settings of the Domain Name System (DNS) are correctly configured (see section Domain Name System (DNS) on page 29). Contact your network administrator for more information and assistance. 17
3.3 Camera Name The camera can be assigned a unique name which then is displayed in an external application 2) and, in addition, can be inserted directly into the video (max. 16 characters). Open the Camera name dialog via Common settings > Camera name.... Fig. 3-5 Enter a unique name for the camera. From the Insert name in video drop-down list, select the position where the camera name is required to be inserted directly into the video. From the Color drop-down list, select the color for the characters that are displayed directly in the video. The color option automatic automatically displays the characters of the camera name in either black or white depending on the current image content (image brightness based on pixel values). This option provides for a better readability of the camera name and is particularly useful if the surrounding contrast or brightness levels at the specified position are constantly changing. Confirm with OK. 2) e.g. SMAVIA Viewing Client (Dallmeier video management software) 18
3.4 User Management The configuration of the device is accessible for authenticated and authorized users only. The user management allows you to grant multiple access levels to the device and to select custom permission settings for three different local user groups. In addition, individual local users can be assigned to each user group if necessary. Furthermore, a centralized user and group management based on LDAP (Lightweight Directory Access Protocol) is supported using an Active Directory (AD) service such as Microsoft Windows Server *) or Linux *) Server with Samba. 3.4.1 Information about User Names and Passwords For security reasons, passwords should consist of at least 8 characters. Do not use any personal information, conventional expressions (real words) or names. A secure password needs to be complex, random and long. A combination of upper-case letters (e.g. ABC), lower-case letters (e.g. abc), numerals (e.g. 123) and non-alphanumeric keyboard symbols (e.g. _ / ^) is usually secure. Character Sets Supported by the Camera The following character sets are supported by the camera: ISO-8859-1 (all languages except Russian) Windows-1251 (Russian language only) Characters Supported by Dallmeier Recording Systems NOTICE Invalid user name or password due to unsupported characters Dallmeier recording systems currently only support a combination of the following characters: Upper-case letters (A Z) Lower-case letters (a z) Digits (0 9) Non-alphanumeric keyboard symbols ( _ -. ) In addition, user names must always start with a letter. 19
3.4.2 Login Mode The login mode defines the authentication type: Login Mode Group login User login LDAP login Authentication Type Group password User name + user password or Group password LDAP user name + LDAP user password An authentication with the group password is also possible in the User login mode. Open the Login options dialog via Common settings > User management > Login options.... Fig. 3-6 Note the following sections on the various login modes. Select the required Login mode. Confirm with OK. 20
3.4.2.1 Group Login Group Name The factory default group names of the three local user groups are: Group 1: admin Group 2: user Group 3: guest The name of each user group can be changed. Group Password Note that a factory default password is set for the local user group Group 1: admin (Default: 3). the factory default password of the local user group Group 1: admin must be changed for security reasons. no factory default password is set for the local user groups Group 2: user and Group 3: guest. a login of the local user groups Group 2: user and Group 3: guest is only possible after a password has been set. Open the User groups dialog via Common settings > User management > User groups.... Fig. 3-7 Click the tab of the relevant group. Enter a new Group name if required. Enter a New password (pay attention to section Information about User Names and Passwords on page 19). Repeat the new password in the Confirm password field. Confirm with Apply. 21
3.4.2.2 User Login In the User login mode, individual local users can be assigned to the three local user groups. Define New User Ensure that the User login mode is selected (see section Login Mode on page 20). Open the User groups dialog via Common settings > User management > User groups.... Fig. 3-8 Click the tab of the relevant group. Click New. The New user dialog is displayed: Fig. 3-9 Pay attention to section Information about User Names and Passwords on page 19. Enter a new User name. Enter a New password. Repeat the new password in the Confirm password field. Confirm with OK. Edit or Delete User Ensure that the User login mode is selected (see section Login Mode on page 20). Open the User groups dialog via Common settings > User management > User groups.... Click the tab of the relevant group. In the Users list, select the relevant user. Edit or Delete the user by clicking the appropriate button. 22
3.4.2.3 LDAP Login This setting allows for an LDAP-based centralized user and group management using an Active Directory (AD) service such as Microsoft Windows Server or Linux Server with Samba. The individual user rights/permissions are granted by three different group policies defined on the LDAP client (this device). NOTICE Login failure In the LDAP login mode, a login as a local user group or a local user is no longer possible. Incorrect LDAP settings The following LDAP settings may only be performed by an administrator with advanced skills in LDAP technology. In order to be able to set the respective group policies/rights on the LDAP client (this device), each LDAP user intended to obtain access to the device must first be assigned to a specific LDAP group on the LDAP server. Then, the defined LDAP group (user-group-relation) can be read out by the LDAP client (this device). A valid LDAP group name for each directory entry on the LDAP server must be structured as follows: [Group prefix][group suffix] The group prefix is a user-definable expression (e.g. myhostname), however, it is required. This allows administrators to assign different user groups and, thus, variable user rights to multiple simultaneously installed LDAP clients of the same system design (e.g. Dallmeier HD cameras described here). The available group suffixes are fixed expressions: Group 1 (administrator): _G4 Group 2 (user): _G2 Group 3 (guest): _G1 On the LDAP server, the LDAP group names with the group prefix myhostname would in this case be as follows: Group 1 (administrator): myhostname_g4 Group 2 (user): myhostname_g2 Group 3 (guest): myhostname_g1 However, it is mandatory to also enter the used group prefix (here: myhostname) on the LDAP client (this device). For further information regarding this requirement, see the following descriptions. 23
Note that the following settings require at least one existing LDAP user to be a member of Group 1 (administrator). After the LDAP settings have been made on the LDAP server, the LDAP client (this device) must be configured accordingly. In this respect, note the following steps and descriptions: Ensure that the LDAP login mode is selected (see section Login Mode on page 20). Click the LDAP options tab. Fig. 3-10 For the correct access to the directory entries on the LDAP server, the following information must be entered: LDAP server: LDAP host: LDAP base: Name or IP address of the LDAP server Example: ldap://servername ldap://192.168.57.3 Group prefix of LDAP group name Example: myhostname Base DN (Distinguished Name, search base on the LDAP server); object location in the LDAP directory hierarchy Example: ou=department,dc=example,dc=co,dc=uk LDAP filter: Default entry: (samaccountname=%unam%) LDAP attributes: Default entry: memberof Enter the relevant data for the access to the LDAP server. 24
Before you can save the LDAP settings, your entries have to be verified. The validation is performed by querying the LDAP directory for an existing authorized LDAP user with administration rights (member of Group 1). The settings on the LDAP client (this device) can only be saved if the query has been successful (returns an internal valid result). Click Test. The corresponding dialog is displayed: Fig. 3-11 Enter the LDAP user name and associated LDAP user password of an authorized LDAP user with administration rights (member of Group 1). Click Start test. After a successful test, confirm with OK to save the settings. From this point in time, a login to this device (now LDAP client) is possible for authorized LDAP users only. 25
3.4.3 Rights The three user groups and, thus, the assigned users can be granted individual rights. In addition, the general public (user group anonymous ) can be granted or denied access to certain types of live images. Note that the rights of Group 1 (administrator) cannot be restricted. certain permission levels cannot be set for all rights. certain rights are partially or fully relevant for external applications only (e.g. for the DaVid Protocol). Open the Rights configuration dialog via Common settings > User management > Rights.... Fig. 3-12 The various user rights are each displayed in a separate row. The permission level of each user group (column) is represented by an icon (see below). 26
Icon Tooltip Permission allow allow read only deny The dialog will be displayed. The settings can be changed. The function can be used. The dialog will be displayed. The settings can NOT be changed. The dialog will NOT be displayed. The settings can NOT be changed. The function can NOT be used. Find the relevant user right (row). Change the permission level by clicking on the icon in the column of the relevant group. Proceed as described above for all user rights and groups. Confirm with OK. 27
Chapter 4: Network 4.1 Basic Settings The network settings of the device can be configured manually or automatically assigned by a DHCP (Dynamic Host Configuration Protocol) server. NOTICE Network conflicts due to invalid or incorrect IP address In order to avoid network conflicts, you should clarify if the intended network settings are permitted. In particular, the allocation of an already used IP address may result in malfunctions. Open the Network settings dialog via Network > Basic settings.... Fig. 4-1: Network settings and MAC address of the device Default Factory Settings Connection type: automatic Bandwidth limit: none Get IP settings from DHCP: unchecked IP address: 192.168.2.28 Netmask: 255.255.255.0 Gateway: 192.168.2.1 Allow IP-Finder network configuration: selected (checked) 28
NOTICE Network connection failures due to incorrect configuration settings Incorrect settings may result in the device being no longer available over the network. Contact your network administrator for more information and assistance. For troubleshooting purposes, write down the MAC address of the device and all new settings before changing the configuration. Note the following explanations. Connection Type This Connect type setting defines the transfer rate and duplex mode. The connection type automatic (Autonegotiation) is sufficient for most applications. Bandwidth Limit Limiting the bandwidth (maximum allowed peak bit rate) can be useful to prevent video artifacts or frame drops due to packet loss with low-bandwidth connections. Domain Name System (DNS) Since IP addresses are rather difficult to remember, you can also refer to devices by their host names which allows you to locate the devices or hosts more easily in the LAN (Local Area Network). The mapping of host names to their corresponding IP addresses is handled by the so-called Domain Name Service (DNS server required). In addition, the IP address mapping can also be stored directly in the hosts file on your local computer. The Host name (or more accurately, the short host name) specifies the name of the machine itself (e.g. myhostname). The Domain name is usually the network domain within your LAN associated with your company and department (e.g. example.com or intranet.example.com). Host names are resolved by special DNS servers, also known as name servers. Resolving host names into IP addresses requires the assignment of a primary name server ( DNS server 1, e. g. ns1.example.com) and, for reasons of reliability and availability, a secondary name server ( DNS server 2, e.g. ns2.example.com). For example, to refer to the device by its long host name or fully qualified domain name (FQDN), you can simply use myhostname.example.com. Depending on the settings of the DNS server or entries in your local hosts file, you can also refer to the device by simply using its short host name (here: myhostname). Search domains (max. 5 allowed, separated by spaces) are useful if a defined alarm host or UTC time server is not located in your specified Domain name. 29
4.1.1 Manual Configuration If no DHCP server is available in your Local Area Network (LAN) or if you want to assign the network settings manually, proceed as follows: First, pay attention to the designated and valid IP address ranges in your network. Contact your network administrator for more information and assistance. Ensure that the Get IP settings from DHCP check box is not selected (unchecked). Enter the IP address that you want to assign to the device. Enter the Netmask. Enter the Gateway address. If required, configure the available DNS settings (see section Domain Name System (DNS) on page 29). If required, clear (uncheck) the Allow IP-Finder network configuration 3) check box. Confirm with OK. The connection to the device is then terminated and the new network settings will be assigned. After changing the network settings, you have to re-establish a connection to the device (with the newly assigned IP address). 3) IP-Finder (PService): Dallmeier software for the determination and configuration of network-compatible Dallmeier devices 30
4.1.2 DHCP To have a DHCP server assign the network settings automatically, proceed as follows: Ensure that an active DHCP server is available in your Local Area Network (LAN). Contact your network administrator for more information and assistance. Select (check) the Get IP settings from DHCP check box. The IP address, subnet mask and gateway address can then no longer be set manually but are automatically assigned by the central DHCP server after saving the network settings. If required, configure the available DNS settings (see section Domain Name System (DNS) on page 29). To send the Host name to the DHCP server, clear (uncheck) the Get host name from DHCP check box and enter a specific host name. If required, clear (uncheck) the Allow IP-Finder network configuration 4) check box. Confirm with OK. The connection to the device is then terminated and the new network settings are assigned by the DHCP server (pay attention to the lease duration). After changing the network settings, you have to re-establish a connection to the device (with the newly assigned IP address): The newly assigned IP address can be determined in the IP Finder (PService) or on the DHCP server by searching for the MAC address of the device. The IP Finder (PService) must be running on the same LAN where this device is located. 4) IP-Finder (PService): Dallmeier software for the determination and configuration of network-compatible Dallmeier devices 31
4.2 Security This setting enforces the encryption of DaVid 5) credentials. Note that this setting does not encrypt the login credentials when you log on to the WebConfig user interface of the device via a web browser. If the security option is activated, the device will only accept encrypted credentials in the authentication data of external applications via the DaVid protocol. The device will, then, no longer accept authentication credentials in plain text but only send and accept DaVid commands that contain encrypted user names or passwords. NOTICE Access failure due to incorrect configuration settings Note that older applications that do not support an encrypted authentication may no longer access the device when the security option is activated. Open the Security dialog via Network > Security.... Fig. 4-2 Select (check) the Force encrypted credentials check box if required. Confirm with OK. 5) Dallmeier Video Protocol 32
4.3 Streaming 4.3.1 Video Server The (static) video server provides for a continuous transmission (streaming) of the generated video data into the network, even without an application s active data request. NOTICE Streaming failure due to incorrect configuration settings Note that the format of the RTP payload that is to be transported must correspond with the used encoding standard. For information on encoder settings, see section Encoder Settings on page 59. Open the Streaming dialog via Network > Streaming.... Fig. 4-3 Note the following explanations. Select an encoder from the Input drop-down list. Select the transfer protocol, format and method from the Mode drop-down list. Depending on the selected transfer method, enter the Multicast IP Address or the Destination IP address. In the Port (1024 65535) field, enter the port number of the service that is required to receive the IP data packets. Enter the TTL value for IP packets into the TTL (0 255) field. Select (check) the RTCP check box if you want to generate and send RTCP packets. Confirm with OK. 33
4.3.1.1 Transfer Protocol and Format Transfer Protocol The transfer protocol defines the communication rules for the data exchange over the network. The (static) video server exclusively transports the IP packets using UDP (User Datagram Protocol). Note that UDP allows for a smooth and fast data transmission with relatively low delays. packet loss (lack of images) may occur with UDP connections. Transfer Format The transfer format defines the RTP payload that is to be transported. NOTICE Streaming failure due to incorrect configuration settings Note that the format of the RTP payload that is to be transported must correspond with the used encoding standard. For information on encoder settings, see section Encoder Settings on page 59. RTP/H264 The video data is packetized by the Real-Time Transport Protocol (RTP) for an H.264 Video Elementary Stream. Audio data is not transferred. The data must be encoded using H.264. The packaging is based on the following standards: RFC3550 - RTP: A Transport Protocol for Real-Time Applications RFC3551 - RTP Profile for Audio and Video Conferences with Minimal Control RFC3984 - RTP Payload Format for H.264 Video RTP/MJPEG The video data is packetized by the Real-Time Transport Protocol (RTP) for an MJPEG Video Stream. Audio data is not transferred. The data must be encoded using MJPEG. The packaging is based on the following standards: RFC3550 - RTP: A Transport Protocol for Real-Time Applications RFC3551 - RTP Profile for Audio and Video Conferences with Minimal Control RFC2435 - RTP Payload Format for JPEG-compressed Video 34
4.3.1.2 Transfer Method The transfer method defines the data distribution over the network. Multicast The data packets are provided with the specified IP multicast address and port number and then transferred to a group of receivers (clients) using a point-to-multipoint connection. The packets have to be transferred only once; the distribution is done by especially configured routers (capable of IP multicasting). A client will only receive the data packets if it has (already) joined the IP multicast group and if the appropriate application service is available at the specified port number. IP multicast uses the address range between 224.0.0.0 and 239.255.255.255 (Class D). Note that certain IP multicast address ranges are reserved for special purposes. For intranet applications, the use of addresses ranging from 239.0.0.0 to 239.255.255.255 is recommended. Contact your network administrator for more information and assistance. Unicast The data packets are provided with the specified destination IP address and port number and then transferred to exactly one receiver (client) in the network using a point-to-point connection. The client will only receive the data packets if the appropriate application service is available at the specified port number. 4.3.1.3 TTL The TTL (Time To Live) value defines the lifetime of an IP packet. Each router an IP packet passes through reduces the time-to-live value by one (1). As soon as the value has reached zero (0), the IP packet is discarded. While preventing IP packets from endlessly circulating in the network due to routing errors, this method stops IP packets from breaking through the limits of the LAN (Local Area Network) and being sent to the WAN (Wide Area Network) (TTL = 1). Depending on the requirements, a TTL value ranging from 1 255 can be entered. If you enter 0 (zero), the default values are used (TTL = 1 for multicast, TTL = 64 for unicast). 4.3.1.4 RTCP The Real-time Transport Control Protocol (RTCP) is an extension to the Real-time Transport Protocol (RTP) and is used for i.a. the transmission of periodic status information such as timestamps of the transmitted video streams. 35
4.3.2 Dynamic Servers A dynamic server is created whenever a UDP or TCP data transmission is actively requested, for example, by the Dallmeier Live Video ActiveX, the DaVid Protocol, the Real Time Streaming Protocol (RTSP) or the SMAVIA Viewing Client. The Dynamic servers tab provides information on currently created dynamic servers. Fig. 4-4 The removal of dynamically generated servers is useful whenever servers, which are no longer used and have not been quit (stopped) by a request automatically, are to be deleted manually. 36
4.3.3 Audio Client This section applies to the following Dallmeier HD cameras that are equipped with an analog Audio OUT interface: Box Cameras DF4620HD-DN Dome Cameras DDF4620HDV-DN In the Audio client tab, the processing of audio data, sent to the device by external applications using the User Datagram Protocol (UDP), is configured. The available settings allow you to activate the output of the received audio data on the analog Audio OUT interface of the device. Fig. 4-5 Note the following requirements for the output of audio data on the analog Audio OUT interface: The audio format of the audio source and the audio format defined in the audio client of the camera ( Mode drop-down list) must be compatible. The defined destination port in the audio source and the port registered in the audio client of the camera (input field Port (1024 65535) ) must be identical. With unicast, the audio source must transmit to the IP address of the camera and the IP address of the audio source ( Source IP address ) must be registered in the audio client of the camera. With multicast, the IP multicast address used by the audio source must be identical with the Multicast IP address registered in the audio client of the camera. For descriptions about the different transfer methods unicast and multicast, see section Transfer Method on page 35. 37
If UDP is used to transmit the audio data, the settings in the audio client of the camera must be configured manually. If the DaVid Protocol is used to control the audio output, the necessary information is sent to the audio client of the camera automatically. Note that the settings in the Audio client tab are disabled if the audio output is controlled using the DaVid Protocol (e.g. with SMAVIA Viewing Client). Controlling the Audio Output with SMAVIA Viewing Client To control the audio output with SMAVIA Viewing Client, proceed as follows: In SMAVIA Viewing Client, right-click the split of the respective camera. In the context menu, select the required audio format and bit rate via Recorder > Transmit Audio. SMAVIA Viewing Client will then transmit incoming audio data (e.g. from the microphone input of the PC) over the network to the audio client of the camera using the DaVid Protocol. The camera decodes the receiving audio data and outputs the generated analog audio signals on the analog Audio OUT interface of the camera (e.g. on a connected speaker). 38
4.3.4 RTSP The Real Time Streaming Protocol (RTSP) is used to control the continuous transmission of multimedia content over IP based networks (media streams). RTSP uses a direct (bidirectional) communication with the RTSP streaming server of the camera. On the one hand to determine the appropriate transmission protocol for the RTP data transfer (UDP or TCP). On the other hand to transmit control actions of IP-based RTSP applications (players) such as the starting and stopping of video transmissions. The encoding, packaging and transport of the data streams from server to client is carried out unidirectionally using the Real-Time Transport Protocol (RTP). Usually, RTP transmissions of streaming content are realized by using UDP (User Datagram Protocol). However, RTSP transmissions are realized over a TCP connection (TCP = Transmission Control Protocol). The following points need to be considered for RTP transmissions using UDP: UDP is a so-called unreliable and connectionless communication protocol. No connection is established to the receiver/client prior to the data transmission. The receiver/client does not acknowledge the receipt of data. During data transmissions over UDP, packet loss (lack of images) may occur. Lost packets will not be sent again. Usually, UDP packets sent from the Internet to your Local Area Network (LAN) are blocked by Internet routers/firewalls in general. UDP allows for smooth and fast data transmissions with relatively low delays, i.e. with low packet delay variation (low jitter ). Each RTSP/RTP transmission over UDP requires three ports to be open: A static port for the RTSP control commands (standard port number: 554) and two dynamic ports for the RTP data stream. The following points need to be considered for RTP/RTSP transmissions over TCP: TCP is a so-called reliable and connection-oriented communication protocol. A connection to the receiver/client is established prior to the data transmission. The receiver/client confirms the receipt of each IP data packet by sending an acknowledge packet. During data transmissions over TCP, usually, no packet loss occurs (unless in the case of a buffer overload in the camera due to a permanent network overload). However, data transmissions over TCP may be slower than data transmissions over UDP. Usually, only the RTSP port must be open at the Internet router or the firewall to receive data transmissions of RTP/RTSP/TCP packets sent from the Internet to your Local Area Network (LAN). RTSP allows you to embed the transmission of RTP streams into the existing RTSP/TCP connection; a separate UDP transmission or an additional port for the RTP data stream is not necessary. 39
In the RTSP tab, you can configure the RTSP server in the camera. Fig. 4-6 The standard port number for RTSP is 554. In the RTSP server port field, the port number can be changed according to your requirements. To generally prevent access to the RTSP server in the camera, i.e. not to allow any RTSP transmission, the corresponding check box can be unchecked. RTP over RTSP Buffer Note that the following section only applies to RTP transmissions over RTSP/TCP. If the network is busy or if a switch within the network, respectively the receiver/client, no longer accepts additional data, the camera can no longer send further image data. The result is a so-called data backlog in the camera. In order to prevent a loss of images, the yet unsent image data can at least for a short time be saved in an internal RTSP buffer (default capacity 1024 kbytes). Only in case of a buffer overload are all saved images lost. Persistent network overload results in a delay in displaying the images at the client. The delay is proportional to the set size of the buffer (amount of images saved). A large RTSP buffer is only recommended in case of short-term network overloads. In case of a persistent network overload, a smaller buffer as well as lower bit rates are recommended for the individual encoder settings. 40
Chapter 5: Video 5.1 Video Standard Countries and territories use different broadcasting television systems. To ensure a correct video signal transmission, the device must be set to the appropriate video standard for your country: HD 25/50 fps for PAL countries HD 30/60 fps for NTSC countries Open the Video standard dialog via Video > Video standard.... Fig. 5-1 Note that the Video standard dialog may be locked by external devices/applications (e.g. by Dallmeier recording systems). Select the appropriate Standard for your country. Confirm with OK. 41
5.2 Sensor In the sensor settings, the image sensor can be configured and the image processing algorithms can be adjusted to the local lighting conditions. In addition, depending on the camera model, the behavior of the built-in P-Iris lens can be defined and the automatic day/night operation can be configured for an optimum image exposure at night. Open the Sensor settings dialog via Video > Sensor.... Note the following explanations on the various sensor settings. Set the relevant options. Confirm with OK. You can restore the factory sensor settings at any time by clicking Default. 5.2.1 Global Settings In the Global tab, the following settings can be configured: Fig. 5-2 42
5.2.1.1 Preset By using Automatic Exposure Presets (AE Presets), the sensor configuration can be adjusted very easily to most lighting conditions in order to always obtain highest image quality. In addition, AE Presets can be used as useful starting points for the manual fine adjustment of various camera parameters. The following AE Presets are available: Universal Factory default AE Preset Suitable for most lighting conditions Optimized for high-contrast scenes (e.g. mixed indoor/outdoor daytime scenes) Indoor Optimized for indoor scenes with medium contrast Obtains improved detail resolution in the highlights Fluorescent Optimized for low-contrast indoor scenes with fluorescent light sources (e.g. fluorescent lamps) Obtains improved detail resolution in the highlights Best results are achieved without incident daylight Typical 50/60 Hz video flickering and fluorescent color roll when using fluorescent lamps can be largely prevented When selecting the AE Preset Fluorescent, the Wide Dynamic Range (WDR) mode is automatically deactivated. A manual reactivation of the WDR mode in conjunction with the AE Preset Fluorescent is not recommended. For more information on the WDR mode, see section WDR Mode on page 48. Only use the AE Preset Fluorescent for indoor scenes when using fluorescent lamps. When capturing outdoor scenes in conjunction with the AE Preset Fluorescent, this may result in excessive overexposure. 43
Notes for the Use of Fluorescent Light Sources (Fluorescent Lamps) With fluorescent light sources (e.g. fluorescent lamps), typical 50/60 Hz video flickering and fluorescent color roll may occur in the video image (see below). If you notice any of these effects in the video image, deactivate the WDR mode or select the AE Preset Fluorescent. 50/60 Hz Video Flickering Typical 50/60 Hz video flickering (strobe effect) may be caused by a significant frequency mismatch between the vertical frame rate of the camera and the flicker frequency of alternating current (AC) powered fluorescent light sources (e.g. fluorescent lamps). Example: When using the camera in NTSC standard (30/60 fps) and with fluorescent light sources, video flickering will occur in countries where the AC power frequency is 50 Hz, which drastically differs from the NTSC video capture standard frequency of 59.94 Hz. Fluorescent Color Roll The phenomenon fluorescent color roll may be caused by a minor frequency mismatch between the vertical frame rate of the camera and the flicker frequency of alternating current (AC) powered fluorescent light sources (e.g. fluorescent lamps). Example: Color roll will occur when using the camera in NTSC standard (30/60 fps) and with fluorescent light sources which are operated at a mains frequency of 60 Hz. Here the mains frequency slightly differs from the NTSC video capture standard frequency of 59.94 Hz. The reason for the periodically occurring color fluctuations is that the color temperature (spectral characteristics) of the fluorescent light source changes within each AC power cycle (each zero crossing of the alternating voltage) which results in brightness variations (illumination level changes). Frequency mismatch normally does not occur when the PAL standard (25/50 fps) is used in conjunction with 50 Hz AC power. 44
Casino Note that, depending on the model, the Casino preset is not available ex works but requires an extra activation using a license code (for more information on license codes, see section Licenses on page 93). The Casino preset is available ex works for the following Dallmeier HD cameras: Box Cameras DF4620HD-DN Dome Cameras DDF4620HDV-DN The Casino preset is optionally available for the following Dallmeier HD cameras: Dome Cameras DDF4220HDV Picodome DDF4320HD-DN DDF4520HDV-DN The Casino preset is optimized especially for: the differentiation of playing cards along with light-reflecting chips on a poker table, the differentiation of light-reflecting chips on a gambling table, the identification of numbers on a fast spinning roulette wheel, and an improved detail resolution of persons and dark objects in scenes with blinking slot machines. The (optional) Casino license allows you to capture images with 50/60 fps at 720p (see section Encoder Settings on page 59). The recording with 50/60 fps is supported by the following Dallmeier recording systems: DIS-2/M NSU 45
5.2.1.2 Color The following color options are available: Automatic This setting enables the automatic switching between black-and-white and color mode as lighting conditions change. The automatic switching depends on the ambient light level: At low light levels the camera automatically switches to black-and-white mode and removes the color burst. Without color information, or rather in black-and-white mode, the image quality in low-light conditions is much clearer (e.g. less color noise). Depending on the ambient light (when a certain brightness level is reached again), the camera automatically switches back to color mode. On The video is always displayed in color, even at low light levels. Off The video is always displayed in black-and-white. 5.2.1.3 Flip By using the flip function, the image in the camera can be mirrored (flipped) horizontally, vertically or on both axes simultaneously. This provides flexible installation options for desktop, wall or ceiling applications. 5.2.1.4 Brightness This setting defines the overall image brightness by a linear adjustment of the tonal values. 5.2.1.5 Contrast This setting is useful to adjust the difference in brightness between light and dark areas. 5.2.1.6 Sharpness This setting influences the perceived sharpness by edge enhancement. 5.2.1.7 Saturation This setting defines the colorfulness and luminance of colors and therefore their perceived intensity. 46
5.2.1.8 Slow Shutter Limit For a proper exposure, the camera automatically determines the best combination of shutter speed, signal gain and, depending on the camera model, aperture (iris opening). The Slow Shutter Limit defines the maximum allowable automatic exposure time (electronic shutter speed). As soon as the set shutter limit is reached, the Automatic Exposure (AE) is exclusively controlled by the Automatic Gain Control (AGC) and, depending on the camera model, the automatic iris (aperture) control. 47
5.2.1.9 WDR Mode The Wide Dynamic Range (WDR) mode allows for an improved color reproduction and detail resolution in scenes with extremely high contrast and strong backlighting. In WDR mode, wide dynamic range images are produced by combining long-exposure signals of dark image areas (normal shutter speed) with short-exposure signals of very bright image areas (high-speed shutter) which then results in an improved dynamic range and, thus, higher detail reproduction in both shadows and highlights. Available WDR options: Automatic This option automatically activates or deactivates the WDR mode according to the prevailing intensity difference of brightness levels between dark image areas and bright image areas. On The WDR mode is always activated. Off The WDR mode is always deactivated. Note that changes in brightness and contrast may be observed in the image when the WDR mode is activated. in WDR mode, the so-called solarization effect (complete or partial reversal of tones with extreme bright light sources) may be observed with some objects. This phenomenon only occurs in WDR mode and is not an indication of a camera malfunction. Fig. 5-3: Solarization effect When selecting the AE Preset Fluorescent, the Wide Dynamic Range (WDR) mode is automatically deactivated. A manual reactivation of the WDR mode in conjunction with the AE Preset Fluorescent is not recommended. For more information on the AE Preset Fluorescent, see section Preset on page 43. 48
5.2.1.10 Lens (CS-Mount Cameras) This section applies to the following Dallmeier HD cameras that are equipped with a CS lens mount and a DC auto iris interface: Box Cameras DF4620HD-DN Dome Cameras DDF4620HDV-DN Available settings: DC control Required setting when using DC auto iris lenses. Off Required setting when using lenses with manual aperture control. 49
5.2.1.11 Lens (P-Iris Cameras) This section applies to the following Dallmeier HD cameras that are equipped with a P-Iris lens: Dome Cameras DDF4320HD-DN DDF4520HDV-DN The P-Iris technology is designed for the precise and automatic adjustment of the ideal iris opening ( optimum aperture ). Compared with conventional DC auto iris lenses, P-Iris (Precise Iris) attains a significantly improved image quality with excellent contrast, brilliant clarity and increased detail resolution with, at the same time, a larger depth of field under almost all lighting conditions. Especially when monitoring objects in different distances to the camera, such as in extended hallways, waiting areas or parking lots, maximizing the depth of field is crucial to the quality of the results of a later image analysis. In cases of extremely bright lighting conditions, the P-Iris technology prevents the effect of a so-called diffraction blur (reduction of the overall image sharpness). This effect would typically occur with conventional DC-controlled auto iris lenses (especially with high-resolution megapixel cameras, due to a smaller sensor pixel pitch) when automatically stopping down too far (high f-stop number). Available settings: Auto P-IRIS Together with the P-Iris lens, the camera software, first of all, automatically determines the most ideal compromise (also known as optimum aperture ) between depth of field, lens resolution and diffraction and, then, continually adjusts the diaphragm opening (aperture) accordingly with a stepping motor. For best focusing results during the camera installation, P-Iris automatically selects the widest aperture and, with it, the smallest depth of field. Hence, it is later able to achieve perfect image sharpness regardless of the prevailing lighting conditions. Manual P-IRIS This option allows you to manually adjust the P-Iris aperture (see section Iris on page 51). 50
5.2.1.12 Iris This section applies to the following Dallmeier HD cameras that are equipped with a P-Iris lens: Dome Cameras DDF4320HD-DN DDF4520HDV-DN Fig. 5-4: Global sensor settings (P-Iris cameras) Note that the Iris setting is only enabled if the setting Manual P-IRIS is selected from the Lens drop-down list (see section Lens (P-Iris Cameras) on page 50). Available settings: 50 % [Slider on left position] Fixed diaphragm opening (aperture) for largest possible depth of field. 100 % [Slider on right position] Maximum aperture (diaphragm opening); useful, for example, under very dark lighting conditions. 51
5.2.2 Expert Settings In the Expert settings tab, the following camera parameters can be configured: Fig. 5-5 5.2.2.1 Exposure/WB To always reproduce accurate colors, regardless of the prevailing light sources and color temperatures (measured in Kelvin), a correct white balance is required. For this purpose, the camera provides the following white balance modes: Auto ATW (Auto Tracking White Balance): The white balance value is automatically calculated using the color information of the entire scene and continually adjusted to the changes of color temperatures. For best results, at least one white object (as reference white) should be within the scene that is to be captured. The use of ATW is especially recommended for scenes with constantly varying lighting situations/color temperatures such as indoor scenes with artificial light sources and incident daylight. One Push One Push AWB (Automatic White Balance): The One Push white balance returns a fixed measurement value which is only recalculated when triggered by user request ( Apply button). The calculations are based on the assumption that, in correct lighting conditions, a white or neutral grey object (as reference value) takes up more than half of the entire scene. Manual White Balance This setting allows you to manually adjust the white balance value to the prevailing color temperature using the Color temperature (K) slider (available color temperature values: 2500 6500 K). By clicking the OK button, the selected color temperature value is applied. By clicking the Get parameters button, the white balance value is automatically recalculated using the color information from the entire scene, or rather reset to the prevailing color temperature in the scene. 52
5.2.3 Day/Night This section applies to the following Dallmeier HD cameras that are equipped with a removable IR cut filter and an integrated ambient light sensor: Box Cameras DF4620HD-DN Dome Cameras DDF4320HD-DN DDF4520HDV-DN DDF4620HDV-DN The above-mentioned cameras are designed to produce high-quality images in daylight as well as under low-light conditions or even at night. In the Day/Night tab, the following settings can be configured: Fig. 5-6 5.2.3.1 Mode Automatic This setting enables the automatic day/night operation depending on the amount of visible light (detected by the integrated ambient light sensor) and internal defined parameters. In low-light conditions, the camera switches to night mode and the infrared (IR) cut filter is automatically removed (ICR ON) which significantly enhances the sensor s sensitivity for near infrared light. Depending on the amount of visible light (when a certain brightness level is reached again), the camera switches back to day mode and the IR cut filter is automatically moved back into place again (ICR OFF). The day/night switching threshold levels and the response time can be manually adjusted (described in the following sections). 53
Day The day mode is always active. The built-in infrared (IR) cut filter is always placed in front of the sensor (ICR OFF). Night The night mode is always active. The built-in infrared (IR) cut filter is always removed (ICR ON). 5.2.3.2 Threshold Level This setting allows you to manually adjust the day/night switching threshold levels (threshold values of brightness and darkness). Possible values: 0 4 (Default: 2) Higher Level The camera switches to night mode (ICR ON) earlier but back to day mode (ICR OFF) later. Lower Level The camera switches to night mode (ICR ON) later but back to day mode (ICR OFF) earlier. 5.2.3.3 Response Time This setting is useful for further fine adjustments of the automatic day/night switching. The Response time defines the day/night switching delay time once the particular threshold levels are reached. Possible values: 1 sec. 20 min. (Default: 5 sec.) Example: If during the day the camera is operated inside a room with a window that faces a public road, the entire room could become very dark for a short time when a big truck passes. Depending on the set threshold levels for the automatic day/night switching, the camera would normally switch to night mode immediately and, moments later, back to day mode. In the reverse example, there would be a constant unwanted switching from night to day mode and back as soon as the headlights of passing vehicles light up the room. Using the Response time setting, it is, thus, possible to delay the automatic day/night switching. 54
5.3 Exposure Control Using the exposure control, allows you to adjust the automatic exposure metering of the camera. Open the Exposure Control dialog via Video > Exposure Control.... Fig. 5-7 Note the following explanations. Set the relevant options. Confirm with OK. The following exposure metering modes are available: Automatic The entire image is used for exposure metering. This setting is only recommended if the entire image area is illuminated homogeneously. Center (Center-Weighted Exposure Metering; Default Setting) The center image area is prioritized over the outer image areas. This setting is recommended in case the relevant image details are primarily located in the center of the image area rather than the outside margins. 55
Spot Light (Spot Metering) The exposure metering is only determined in the image area defined by the user. That area is, then, exposed ideally. However, the other image areas can be heavily over- or underexposed. This setting is recommended for scenes with extreme variations in brightness and when a specific image area is required to be exposed absolutely correct. In order to define an area for spot metering, proceed as follows: First, select Spot Light from the Exposure Mode drop-down list. Click and hold the left mouse button and draw a rectangle (red) over the relevant image area that you want to define for spot metering. Release the mouse button. Another click within the image removes the defined metering area. Once the area defined for spot metering meets your requirements, click OK. 56
5.4 Privacy Zones This function allows you to hide (mask) up to 4 user-definable areas in the camera to ensure privacy protection and compliance with laws and regulations that prohibit certain locations from being monitored and/or recorded. The defined Privacy Zones are, then, directly blackened in the camera. Note that the combined area of all active Privacy Zones can maximally amount to up to 40% of the entire image. Open the Privacy Zones dialog via Video > Privacy Zones.... Fig. 5-8 Select the zone (1 4) that you want to define by using the appropriate radio button. Click and hold the left mouse button and draw a rectangle (going from the upper left to the lower right) over the relevant image area that you want to hide (mask) in the camera. The selected image area is indicated with a red masking. 57
If the selected image area does not meet your requirements, use the mouse and click on an unmasked area. The red masking is removed and a new image area can be selected. If the selected image area meets your requirements, activate the defined zone by selecting the appropriate check box. Click OK to apply the settings. If you want to define another image area as a Privacy Zone, select the appropriate radio button and proceed as described above. However, if the combined area of all already activated zones amounts to more than 40% of the entire image, you cannot mask any more zones. In that case, reduce the size of the already defined zones and save the settings again by clicking OK. Then, define the new zone. Finally, click OK to save all settings. You should always activate and save each defined zone first ( OK ), before defining another zone. In order to display a previously masked image area again, deactivate the appropriate check box and click OK. The defined image area remains saved in the camera as long as you do not click into an unmasked image area within the corresponding zone. Thus, you can always activate or deactivate the masking for an already defined image area. 58
5.5 Encoder Settings Note that the Encoder settings dialog may be locked by external devices/applications (e.g. by Dallmeier recording systems). In the Encoder settings dialog, the encoding of the video data is configured. Furthermore, the hybrid video output (video over IP and the simultaneous analog video output) can be configured. The generated video images can be recorded in Motion recording mode (image comparison) by Dallmeier recorders of the DMS and VNB series (as of version 7.1.1). Encoder 1 is used for this purpose and has to be set to H.264 encoding. Encoder 2 and 3 are, then, automatically disabled. In addition to recording, a second stream from Encoder 1 can be used for live display if Encoder 1 is set to a bit rate not higher than 6 Mbps. 5.5.1 Encoder 1 Open the Encoder settings dialog via Video > Encoder settings.... The Encoder 1 tab is displayed: Fig. 5-9 Note the following explanations. Select the encoding standard (H.264 or MJPEG) from the Encoder mode drop-down list. Select the frame rate from the Frames/Second drop-down list. The (optional) Casino license allows you to capture images with 50/60 fps at 720p. Further information on activating optional licenses can be found in the section Licenses on page 93. Note that Encoder 2 and 3 are not available if Encoder 1 is set to 50/60 fps. The recording with 50/60 fps is supported by the following Dallmeier recording systems: DIS-2/M NSU 59
Select the Resolution (width height in pixels). In order to achieve an ideal image quality when recording the analog video signal, the resolutions SXGA or 4CIF are recommended at Encoder 1. The resolution 720p at Encoder 1 is not recommended when recording the analog video signal. Select the Bitrate. Select the Bitrate mode. Select the GOP-size (only with H.264). Use the Hybrid Cam check box to define the maximum available frame rates at Encoder 1 and the analog video output. Use the Scale Analog Output check box to define the output of the analog video signal. Confirm with OK. 5.5.1.1 Frames/Second The frame rate (value in fps) defines the number of consecutive frames generated per second. The higher the frame rate, the smoother the video playback. However, higher frame rate also requires higher bandwidth (transmission capacity) and more hard disk storage space for the recording of video material. 25 (PAL countries) or 30 fps (NTSC countries) meet the requirements for real-time applications. The optional Casino license allows you to capture images with 50/60 fps at 720p. Further information on activating optional licenses can be found in the section Licenses on page 93. Note that Encoder 2 and 3 are not available if Encoder 1 is set to 50/60 fps. The recording with 50/60 fps is supported by the following Dallmeier recording systems: DIS-2/M NSU 5.5.1.2 Bitrate The bit rate refers to the number of bits per second used to encode the video. The more bits are used to represent the video data per second, the higher the quality is. However, higher bit rate also requires higher bandwidth (transmission capacity) and more hard disk storage space for the recording of video material. Low bit rate = High image compression = Small data volume = Poor image quality = Low bandwidth and small hard disk storage space required High bit rate = Low image compression = Large data volume = High image quality = High bandwidth and large hard disk storage space required Usually, most requirements in surveillance applications are met with a bit rate between 4 and 6 Mbps. 60
5.5.1.3 Bitrate Mode This setting allows you to configure a constant bit rate (CBR) or a variable bit rate (VBR) for video encoding. A variable bit rate dynamically correlates with the changes in the image. In scenes with many changes in the image, the bit rate is temporarily increased. The admissible deviations from the defined bit rate are indicated in percentages. The higher the percentage value, the higher the maximum admissible peak bit rate and the longer the regulation time to return to the nominal bit rate. Example: In case of a defined (nominal) bit rate of 4 Mbps and a bit rate mode of variable 100 %, the peak bit rate may temporarily increase to up to 8 Mbps. Variable bit rates allow for a higher image quality and a better utilization of available hard disk storage space and transmission capacity. In contrast, a constant bit rate allows for a more accurate calculation of the storage space required. 5.5.1.4 GOP-Size The H.264 encoding (compression) is carried out by dividing the video stream into so-called GOPs (Group Of Pictures) of a defined length ( GOP-size ). A GOP sequence always starts with an Intra-Frame (I-Frame), which contains all image data and serves as a reference for the subsequent images within a GOP. The I-Frame is compressed with a low compression rate, similar to the JPEG compression method. Depending on the defined GOP-size, an I-Frame is followed by one or more Predicted Frames (P-Frames), which only contain the motion predictions and difference information of the preceding images (I-Frame or P-Frames) also called Long-term prediction. The compression rate of P-Frames is much higher than that of I-Frames since changes in relation to reference images only need to be coded as motion vectors. Thus, the required bit rate decreases so that, with a given total encoding bit rate, more bits are available for the I-Frame. Consequently, the quality (e.g. the detail resolution) of the I-Frame can be increased by the use of a larger GOP-size. However, if there are scenes with many motion changes, a high number of P-Frames can have a negative effect on the image quality, because the motion predictions become increasingly inaccurate. Additionally, a larger GOP-size always leads to an increase in delays regarding processing or accessing a stream. A GOP sequence ends before the next I-Frame. Later on, the individual GOP sequences are used to generate the visible single frames (reconstruct the original compressed image data) at the decoder. The GOP-size 1 (I-Frames only) indicates a low compression level and should only be used with specific applications, because the bandwidth requirements increase significantly. In general, a GOP-size between 6 to 15 provides a good image quality with a sufficiently high compression level. Note that reverse playback at high GOP-sizes can lead to frame drops with some decoders. 61
5.5.1.5 Hybrid Cam In addition to video over IP, the hybrid camera allows for a simultaneous analog video output via the built-in BNC connector (CVBS). The Hybrid Cam function defines the maximum available frame rates at Encoder 1 (video over IP) and the analog video output: Hybrid Cam > On [ Hybrid Cam check box selected] Resolution Encoder 1 Frame Rate Encoder 1 Frame Rate Analog Output (4CIF) SXGA max. 12.5/15 fps max. 25/30 fps 720p max. 25/30 fps max. 25/30 fps 720p max. 50/60 fps 6) no analog video output supported 4CIF max. 25/30 fps max. 25/30 fps Hybrid Cam > Off [ Hybrid Cam check box not selected] Resolution Encoder 1 Frame Rate Encoder 1 Frame Rate Analog Output (4CIF) SXGA max. 25/30 fps max. 12.5/15 fps 720p max. 25/30 fps max. 25/30 fps 720p max. 50/60 fps 6) no analog video output supported 4CIF max. 25/30 fps max. 25/30 fps 6) Optional Casino license required 62
5.5.1.6 Scale Analog Output This function defines the output of the analog video signal (4CIF PAL/NTSC, aspect ratio 4:3). In order to achieve an ideal image quality when recording the analog video signal, the resolutions SXGA or 4CIF are recommended at Encoder 1. The resolution 720p at Encoder 1 is not recommended when recording the analog video signal. Scale Analog Output > On [ Scale Analog Output check box selected] If resolution at Encoder 1 = SXGA : Image is scaled to display the entire scene. Image is not cropped. If resolution at Encoder 1 = 720p (aspect ratio 16:9): Aspect ratio is converted to 4:3 format by letterboxing (visible black bars at the top and bottom of the screen). Image is scaled to display the entire scene. Image is not cropped. If resolution at Encoder 1 = 4CIF/4SIF: Image is not scaled or cropped. Scale Analog Output > Off [ Scale Analog Output check box not selected] If resolution at Encoder 1 = 720p, SXGA : Image is cropped. Only partial section of center sensor area is output. Smaller image detail causes reduction of angle of view. Smaller image detail leads to the impression of an increased focal length and an enlarged sectional view (subject appears closer and larger). If resolution at Encoder 1 = 4CIF/4SIF: Image is not scaled or cropped. 63

Chapter 7: Interfaces 7.1 Data Display The Data display function allows you to embed external transaction data or other monitoring information into the video stream. External data can be transmitted directly to the camera by cash registers, automated teller machines (ATMs), access control systems, casino systems (e.g. slot machines) or other monitoring applications using the DaVid Protocol. Depending on the client application or device, the embedded data is then displayed directly in the video image (video text overlay) or in the info area of the corresponding camera split (e.g. during video analysis with SMAVIA Viewing Client). Before embedding external data into the video stream, the received data can be filtered. In addition, you can specify the position and dimension of the video text overlay. NOTICE Video text overlay failure due to incompatible hardware Note that the video text overlay is only displayed in conjunction with the following Dallmeier devices: DIS-2/M DecoderPro HD DIS-2/M Multi-D HD WSD-2 HD In conjunction with the above-mentioned devices, the embedded data is displayed directly in the live video on a connected (via BNC or HDMI interface) monitor as video text overlay. However, a recording of the embedded data must always be configured separately. For this purpose, activate the SW contact or Field contact option in the recording settings (event recording) of the corresponding track. Detailed information on recording embedded data can be found, for example, in the product documentation of the following Dallmeier recording systems: DIS-2/M Multi-D HD DIS-2/M NSU WSD-2 HD 82
7.1.1 Filter Before embedding external data into the video stream, the received data can be filtered. The filtering (selection) affects only to received data, i.e. data that was actually sent from external devices to the camera. Open the Data display - Filter dialog via Interfaces > Data display > Filter.... Fig. 7-1 By default, no external data is embedded into the video stream. To embed received data into the video stream, proceed as follows: First, select (check) the Display active check box. Activate the relevant data by selecting (checking) the appropriate check box. Select the Duration for later data display. Confirm with OK. The received data is embedded into the current image (frame) that is captured exactly at the moment when the external data is received and stays embedded (is displayed) for the selected Duration (frames). 83
7.1.2 Position To prevent covering any important image details, the video text overlay can be positioned in the video image. Open the Data display - Position dialog via Interfaces > Data display > Position.... Fig. 7-2 The right-hand side of the dialog (blue rectangle with Dallmeier logo) represents an exemplary screen for displaying live videos with full PAL or NTSC resolution. Note that the aspect ratio and resolution of the actual screen depend on the used client. The specified coordinates and dimensions for the video text overlay are automatically converted (rescaled) for the screen resolution of the used client (e.g. to Full HD) and matched to its aspect ratio (e.g. to 16:9). The white lines illustrate the stylized graphical user interface (GUI) of a typical application for displaying live videos. The white rectangle with the yellow corner (in the bottom right) shows the display area (video text overlay) for the embedded data. On the left-hand side of the dialog the coordinates ( Horizontal and Vertical ) and the dimensions ( Width and Height ) of the video text overlay is displayed (all values in pixels). The coordinates refer to the top left corner of the video text overlay. 84
The video text overlay can be positioned by drag & drop. Fig. 7-3 The video text overlay can be resized by dragging its yellow corner (in the bottom right). Fig. 7-4 An exact positioning and resizing of the video text overlay is possible by using the corresponding input fields. Adjust all relevant settings. Check the output on the live monitor. Confirm with OK. 85
Chapter 8: Digital Image Shift Since at the resolution of 1280 720 pixels (720p) only a specific area of the sensor is used for image capturing, the Digital Image Shift function allows for a subsequent digital fine alignment of the displayed image section over the network. By using the Digital Image Shift function, the used sensor area can be digitally shifted (vertical alignment by 120 pixels up or down) and, thus, the final section of the scene that is to be monitored can be fine-tuned. That function is particularly useful for adjusting the displayed image section (at 720p) if it does not exactly meet your requirements once the camera has been installed. In the configuration menu, click the Digital Image Shift... menu item. Fig. 8-1 In the example shown above (Fig. 8-1), the displayed image section does not exactly meet the requirements after camera installation. The garage (on the left side of the illustrated image) is only half captured by the image sensor. However, using the arrow buttons, the image section can easily be shifted over the network afterwards. 86
Left-click on an arrow button to shift the image section accordingly. Adjust the Steps slider to a higher level in order to shift the image section faster when clicking an arrow button. In the example shown below (Fig. 8-2), the image section has already been shifted. Now, the garage (on the left side of the illustrated image) is completely captured by the image sensor. Fig. 8-2 To apply the new image section, click Save. To restore the previously saved image section, click Restore. To restore the factory default image section, click Default. The Time-out function allows you to activate the automatic time-based recovery of the last saved image section. 87
Chapter 9: Lens Control (Remote Back Focus Control) This chapter applies to the following Dallmeier HD cameras that are equipped with a CS lens mount and the Remote Back Focus Control function: Box Cameras DF4620HD-DN Dome Cameras DDF4620HDV-DN Besides the manual setting on the lens, the focusing can also be done conveniently over the network. The focusing is carried out by shifting the image plane / sensor unit in the z-direction (+/ ). NOTICE Incompatible system requirements and/or incompatible software versions Note that for displaying the live video, the Microsoft Internet Explorer is required and the latest Dallmeier Live Video ActiveX must be installed on the client PC. In the configuration menu, click the Lens control... menu item. 88
The Lens Control dialog is displayed: A B Fig. 9-1 C D A Live video (image is illustrative only) B UDP or TCP connection (see section Connection Method on page 12) C Manual focusing from far (+) to near ( ), each in steps of 1, 5 or 10; automatic resetting of sensor unit to home position ( Home button) D Scale live video for a better determination of focus and image sharpness (if magnification >1, left-click in the live video, hold the mouse button down and drag the mouse to move the image section) Note the following notes and recommendations. Adjust the relevant settings. Reduce the encoding bit rate to minimize long delays (response times) during focus control with low-bandwidth connections (see section Encoder Settings on page 59). Deactivate the DirectX option in the User interface dialog if the live video turns black (or rather is not displayed) at 8 magnification (see section User Interface on page 15). 89
Chapter 10: Lens Control (Motor-Driven P-Iris Lens) This chapter applies to the following Dallmeier HD cameras that are equipped with a motordriven P-Iris varifocal lens: Dome Cameras DDF4320HD-DN DDF4520HDV-DN The zoom (focal length) and focus adjustments can only be carried out in the Lens Control dialog over the network. NOTICE Damage to the lens unit The motor-driven P-Iris varifocal lens is equipped with high-precision stepper motors. Therefore, do not try to manually adjust the focal length (zoom) and focus on the lens. Incompatible system requirements and/or incompatible software versions Note that for displaying the live video, the Microsoft Internet Explorer is required and the latest Dallmeier Live Video ActiveX must be installed on the client PC. For best focusing results, P-Iris automatically selects the widest aperture and, with it, the smallest depth of field. Hence, it is later able to achieve perfect image sharpness regardless of the prevailing lighting conditions. After 20 25 seconds without user action the diaphragm opening (aperture) of the P-Iris lens is automatically set to its previous f-stop position. In the configuration menu, click the Lens control... menu item. 90

The list of IP addresses is displayed in the Event log dialog. Open the Event log dialog via Service > Event log.... Fig. 11-4 93
11.5 Configuration File The configuration of the device can be exported to a file and, thus, be saved. Besides a configuration recovery of the device that is currently connected, the saved configuration can also be transferred to multiple devices simultaneously. 11.5.1 Download NOTICE Serious network conflicts due to incorrect configurations settings If you want to transfer the configuration file to multiple devices, you must not export the Network settings. Open the Configuration file management dialog via Service > Configuration file > Download.... Fig. 11-5 Select all relevant settings that you want to export to the configuration file by checking the related check boxes. Confirm with OK. Follow the instructions of the download dialog and save the configuration file to a data storage device. The file name of the configuration file contains the IP address of the associated device. 94
11.5.2 Upload The saved configuration file can be transferred to an individual device. This allows for the recovery of the configuration of the device that is currently connected. In addition, the configuration file can also be transferred to multiple devices simultaneously. This is a very effective method to identically configure multiple devices in terms of certain configuration groups. 11.5.2.1 Configuration Recovery To recover the configuration of an individual device, the connection to the device must be established first (see section Connection on page 11). Open the Configuration file management dialog via Service > Configuration file > Upload.... Fig. 11-6 Click Browse.... Select the relevant configuration file from your data storage device. Confirm with OK. The saved configuration settings are then transferred to the device. At the end of the transfer a list of the transferred (or skipped) configuration settings will be displayed. 95
11.5.2.2 Configuration Transfer to Multiple Devices As a precondition for the transfer of the configuration file to multiple devices, all relevant devices must be located in the same LAN (with suitable cabling and a separate IP address for each device). In addition, the login data must be identical for all devices (same user name and password). Before the configuration file can be transferred, it must be saved as described above. However, the configuration of the network settings must not be included in the configuration file. If these settings were included, the same IP address would be transferred to all devices. Since, however, each IP address in a LAN must be unique, this would cause massive problems in the network. NOTICE Serious network conflicts due to incorrect configurations settings Ensure that the network settings are not transferred to multiple devices. Clear (uncheck) the Network settings check box before exporting the configuration file. To be able to transfer the configuration file to multiple devices, the connection to one of the devices must be established first (see section Connection on page 11). Open the Configuration file management dialog via Service > Configuration file > Upload.... Fig. 11-7 Click Browse.... Select the relevant configuration file from your data storage device. Select (check) the Broadcast check box. Enter the First IP address and the Last IP address of the relevant device group. Enter the Username for accessing the devices. Enter the Password for accessing the devices. Confirm with OK. The saved configuration settings are then transferred to all devices in the specified IP address range. At the end of the transfer a list of the transferred (or skipped) configuration settings will be displayed. 96
11.6 Info General information on the device is displayed in the Info dialog. In the configuration menu, click the Info... menu item. The Info tab is displayed. Fig. 11-8 Among other things, the following information is displayed: Device type Software version Encoder version ONVIF version Version number of the Linux Kernel Serial number of the device Uptime (elapsed time since last system boot) Information on the current network connections is displayed in the Network connections tab. 97
Chapter 12: Image Transmission The camera can be configured to stream generated video data into the network in either unicast or multicast mode without a request from a client (see section Video Server on page 33). Furthermore, client devices or applications can send a request to the camera using various transport and data protocols to initiate a transmission of the generated video data. In addition to video over IP, the hybrid camera also allows for a simultaneous analog video output via the built-in BNC connector (CVBS). 12.1 Web Browser 12.1.1 Live Video (ActiveX) The live video can be displayed in the Microsoft Internet Explorer. Data Transfer and Control over TCP Transport protocol TCP Transmission protocol DaVid Protocol Control protocol DaVid Protocol Port (for DaVid Protocol) 30000 Data Transfer over UDP Control over DaVid Protocol/TCP Transport protocol TCP/UDP Transmission protocol RTP/UDP Control protocol DaVid Protocol/TCP Port (for RTP) 18000 20000 (dynamic port detection) Port (for DaVid Protocol) 30000 Note that the latest version of the Dallmeier Live Video ActiveX must be installed on the client PC. the WebConfig live video access right/permission for the user group anonymous must be activated if you want to grant not registered users access to the live video (see section Rights on page 26). Use the following URL request to display the live video in the Microsoft Internet Explorer. http://ip address of the device Example: http://192.168.2.28 98
If the live video is requested from multiple users (client PCs) using the Microsoft Internet Explorer, the network utilization and, thus, the required bandwidth increases proportionally. The maximum supported number of client PCs is also dependent on the encoder settings of Encoder 1 (see section Encoder Settings on page 59). 12.1.2 Single Image (JPEG) Current video data can be requested as a single image (JPEG) by any web browser. Transport protocol TCP Transmission protocol HTTP Port 80 Note that the requested encoder must be configured for MJPEG encoding. the requested encoder must be activated. the JPEG live access right/permission must be activated (see section Rights on page 26). Use the following URL requests for the various encoders: Encoder 1 Encoder 2 http://ip address of the device/live/image0.jpg http://ip address of the device/live/image1.jpg The displayed single image (JPEG) can be refreshed at any time (e.g. by using the F5 key on your keyboard). The query expression (URL request) can also be integrated into an HTML (JavaScript) page that refreshes the image automatically. 99
12.2 RTSP Application The live video can be requested by RTSP clients (e.g. players) and the transmission of the streaming content can be controlled (start and stop) using RTSP. For more information, refer to the section RTSP on page 39. Transport protocol Transmission protocol Control protocol Port TCP/UDP RTP RTSP 554 (default setting) RTSP and RTP over HTTP Tunneling Transmission protocol HTTP Port 80 Note that the requested encoder must be activated. the RTSP server in the camera must be activated (see section RTSP on page 39). the RTSP live access right/permission must be activated (see section Rights on page 26). Use the following URL requests for the various encoders: Encoder 1 Encoder 2 Encoder 3 rtsp://ip address of the device/encoder1 rtsp://ip address of the device/encoder2 rtsp://ip address of the device/encoder3 Encoder 1, 2 and 3 can be requested by three applications simultaneously. This allows you to realize a Tri-Streaming functionality (three streams with different quality). If multiple applications are requesting the data of one encoder, the network load and, thus, the required bandwidth increases proportionally. In this case, a multicast configuration should be preferred since this only requires bandwidth for one stream. 100
12.3 Analog Video Output In addition to video over IP, the hybrid camera allows for a simultaneous analog video output via the built-in BNC connector (CVBS). The maximum available frame rate at the analog video output depends on the settings of the Hybrid Cam function (see section Hybrid Cam on page 62). The output of the analog video signal depends on the settings of the Scale Analog Output function (see section Scale Analog Output on page 63). In order to achieve an ideal image quality when recording the analog video signal, the following resolutions at Encoder 1 are recommended (see section Encoder Settings on page 59): SXGA 4CIF The resolution 720p for Encoder 1 is not recommended when recording the analog video signal. Deinterlacing The HD camera generates progressive image signals (Progressive Scan). Therefore, deactivate the Deinterlacing filter for the respective HD camera in the recording settings of your Dallmeier recording system. Fig. 12-1: Recording settings on Dallmeier recorder: Deinterlace filter deactivated Flickering Effects (Aliasing) Due to the high resolution of the HD camera, flickering effects (aliasing) on sharp edges and fine textures may appear when displaying the analog live video on older CRT (cathode ray tube) monitors that are equipped with interlaced technology. This effect is minimized for the recording and playback on a Dallmeier system. 101
