2 1. Introduction The introduction of firmware 1.52 for the HeiTel devices CamDisc svr 4s and 10s, CamServer 2, CamMobile 4 and 10, CamDisc svr 4 and 10 and CamTel svr 4 and 10 means that the models listed provide a functionality called HTconnect for a leased line between the transmitter and the receiver software. For this, the TCP/IP leased line is always initiated by the transmitter. The correspondinglyconfigured HeiTel devices establish a resting permanent connection to the receiver for this. For this leased line via TCP/IP, each transmitter which is connected with a receiver generates a data volume of around 6 bytes per minute for the resting connection. The use of the TCP/IP leased line is suitable for transmitters with DSL/UMTS connections with dynamic IP addresses, thereby eliminating the need for DynDNS entry (dynamic Domain Name System entry) with the corresponding providers, and for devices within company/provider networks where the firewall restrictively prevents incoming calls. In the following example, the use of the TCP/IP leased line is illustrated using a restrictive firewall. The method of function can also be transferred to DSL and mobile phone connections with dynamic IP addresses. This behaviour is demonstrated, for example, by the fact that alarms or routine calls from the transmitter reach the receiver software at the external control station, but manual calls initiated from the control station for maintenance purposes do not get through.

3 With the TCP/IP leased line, the receiver software uses the standing connection established by the transmitter through the firewall to initiate its own connections to the transmitter in turn. The existing connections on the receiver PC to the various transmitters are indicated via the blue-red flashing surround on the symbol for the HTconnect Server in the taskbar.

4 2. Requirements 2.1. One of the above-mentioned devices with Firmware 1.52 or newer CamControl LITE Software 3.72 or newer; CamControl PRO Software 3.73 or newer Static IP address for addressing the control centre (CamControl software with HTconnect Server) via the Internet 2.4. The possibility for a direct connection to the receiver PC via TCP/IP using a fixed IP address or a symbolic name where dynamic IP addresses are assigned. The relevant information can be obtained from your internet provider or from the responsible system administrator. 3. Setting up the TCP/IP leased line The set-up for the TCP/IP leased line is carried out in three stages: Step 1: Activating the function of the receiver software via an entry in the corresponding configuration file CAMTEL.INI or CAMCTRL.INI (see Step 1) Preparing the transmitter prior to installation in the building (see Step 2) Installing the transmitter in the list of transmitters in the receiver software (see Step 3) Close down the receiver software Open the configuration file for the receiver software: o CAMTEL.INI for CamControl LITE or CAMCTRL.INI for CamControl PRO Locate the section [EXTRA] in the configuration file Add the following entries in the section [EXTRA] or make the corresponding changes: HTCONNECTSVR=1 ; 1 = ON, 0 = OFF (Default) HTCONNECTSVRPORT=3333 ; Default = 3333 Save the changed configuration file Start up your receiver software and check whether the HTconnect Server program is displayed in the taskbar: Open the HTconnect Server status window by double-clicking on the program symbol: o The top part displays program messages. o The bottom part gives details in the status section about: active connections, the total number of connections, and the connection port. Where applicable, it is followed by a list of the transmitters connected, showing the serial number and IP address along with the date and time that the connection was established.

5 Step 2: The following steps are to be carried out prior to installation in the building: Start your receiver software and establish a connection to the corresponding transmitter using the CamControl software via null modem or network. Make sure that the transmitter has suitable firmware 1.52 (or newer). After successfully establishing the connection to the device, open the device settings (Recorder settings/device) by clicking on the Setup button. The status of the firmware (for example V 01.52) is displayed to the right of the term Version. Make a note of the serial number of your transmitter, as this is needed for Step 3. Switch to the settings for the leased line (Recorder settings/connections/htconnect). Check whether the Port number for the leased line corresponds with the settings specified in Step 1. The standard setting is Port: Using the On option, activate the receivers to which a leased line is to be established by the transmitter. The address entries for IP address 1 to IP address 4 cannot be changed in this configuration menu, since these addresses are transferred from the menu Recorder settings/connections/phone & IP numbers. The only freely-selectable address is IP address 5. Technical Product Information HeiTel Digital Video GmbH /7

6 Step 3: Modify an existing transmitter entry or create an entry for the corresponding transmitter. The dialogue box Transmitter index is accessed via Dial/Transmitter index and then either via the Modify button for existing entries or via Add for new entries: Complete the entries and activate the HTconnect option in the Serial number section. The serial number can now be edited. o If you are changing an existing transmitter entry, check whether the serial number noted down previously in Step 2 matches the existing entry. o For a new entry, enter the serial number previously noted down in Step 2 in the corresponding field. Complete entry by clicking OK. 4. General information about the TCP/IP leased line Please take note of the following information regarding the TCP/IP leased line: All connections to transmitters which have been configured in the manner described above have been initiated by the respective transmitter as a standing connection. However, for the user these alarm connections present themselves as receiver calls. Under some circumstances, the details may deviate from a regular receiver call. During this quasi receiver dialling, in exceptional instances, a regular alarm imminent at the same moment can be activated instead of the desired transmitter. The theoretical limit for TCP/IP leased lines is specified by the receiver software, which is limited to 2000 transmitter entries. Please note that the use of large numbers of TCP/IP leased lines can result in performance drops when operating the receiver software. For each connected transmitter, a data volume of approx. 6 bytes/min. is generated. Call Accept must not be switched off in the receiver software settings. The HTconnect Server is managed as an independent program by the receiver software and should remain minimised in the taskbar. A flashing symbol indicates that one or more connections are established to correspondingly-configured transmitters. Technical Product Information HeiTel Digital Video GmbH /7

7 Since correspondingly-configured transmitters always establish a connection to the receiver software from their end, the availability of one or more transmitters for receiver calls can be restricted in particular, immediately after start-up of the receiver software or in the event of changes to the transmitter settings. If necessary, you are informed of this via this information window when dialling the transmitter manually: This window is also displayed if the leased line to the receiver has been deactivated on the corresponding transmitter and the HTconnect option on the receiver software at the receiver for this transmitter is still activated in Transmitter index. 5. Notes regarding use of third-party services We wish to draw your attention to the fact that when using the TCP/IP leased line, a correspondingly-configured transmitter permanently attempts to establish a connection to the receiver. As soon as the connection is established, then per transmitter and per receiver a data volume of 6 bytes per minute respectively is generated. If this is calculated up for a calendar month of 31 days, the "resting" connection in itself generates a data volume of around 270 kilobytes per transmitter for each receiver. If a transmitter establishes TCP/IP leased lines to the maximum possible number of receivers (five), then the data volume is estimated to be around 1.35 megabytes per month. For that reason, you are advised to select a suitable tariff on pay-to-use connections such as DSL or UMTS. Since the connection between the transmitter and the receiver software is permanently established, as it were, whilst the data volume (as described above) is relatively modest on a "resting" connection, a volume tariff should generally be a more cost-favourable option than a time-based tariff for this application. You are advised always to make checks at regular intervals on the data volumes used for the correspondingly-configured connection and on the costs incurred under the chosen tariff! With leased lines via DSL or UMTS (3G), you are making use of third-party provider services as a user.
