4 Live View page Introduction If your browser is Microsoft Internet Explorer, you need to install the ActiveX control on your computer. This document contains information about how to use ActiveX control to integrate the camera live view window into web application. User can embed a camera live view window into web application, or create a customized live view web page. ActiveX Control Technology ActiveX controls small program building blocks can serve to create distributed applications that work over the Internet through Microsoft Internet Explorer web browser. Examples include customized applications for gathering data, viewing certain kinds of files, and displaying animation. ACTi camera also included ActiveX control nveplmedia.cab into firmware, when user connect to camera s web page, the Internet Explorer will allow embedding the ActiveX control, then user can view the video streaming in camera s web page. If you want to embed our ActiveX control into your specially designed webpage, the ActiveX control nvunifiedcontrol.ocx can work with all ACTi cameras whatever the camera firmware is earlier or not. Here is latest ACTi camera s ActiveX control. ACTi Camera ActiveX control Digital signature Internet Explorer ACM TCM KCM D/E/B/I File Name: nvunifiedcontrol.ocx Version: Date: 11/7/2012 Valid from 9/4/2012 to 9/24/ bit version Internet Explorer's default security settings require that any software available for download must have a digital signature before download can occur, the file types which will need digital signature, such as.exe,.cab,.dll,.ocx,.msi,.xpi. How to install ActiveX control to your system Generally ActiveX control will be pushed to user system automatically. However, there may be some cases when the user may not be able to download and install the ActiveX control from the web application. In such case user will need to install the ActiveX control manually. You can find one attachment in this KB named as ActiveX control Installation Pack.zip, after unzipping the file, execute Register OCX.bat, it will install the necessary ActiveX control into 4

This setting is useful to limit the access time for each connection, you can set this value as 0 if you wish to provide a permanent connection. var nlivingtime = 0; Line121: Modify the URL which locates the ActiveX control component. You may choose to host this file on your website, or let your user download from ACTi server. If you wish to host ActiveX control yourself, just replace the bold text with your URL. If you do not wish to host it yourself, you can leave the settings unchanged to let your users download from ACTi server. Please do not modify other settings in this tag. <OBJECT id="nv1" codebase=" AP&Manual/Live%20Demo/nvUnifiedControl.ocx" height="480" width="720" data= "data:application/x-oleobject;base64,p2/zpua6i0wvxkqcvl4l+bahaabhjaaazhgaaa==" classid="clsid:f8e691a0-c92e-4e42-9cda-62fc07a9483b" VIEWASTEXT> 6

11 How to show live view on other browsers Due to other browsers do not support ActiveX, such as Firefox, Google Chrome,etc. You can input the URL command to show camera s video. Please refer to another article: How to Watch Live Video Using iphone and ipad If the camera supports RTSP, you can plug-in media application to show live video, the camera will send the image with dynamic UDP port, please make sure there is no firewall between camera and live view site, here is an example which we use Quicktime application. There is a sample code attached to this article, named as LiveDemoSample_plugin_quicktime.html. This sample is a useful example to set up a live demo page for guest viewers. We will highlight the necessary modification which can help you to get successful preview with this sample. Line 2: Modify the display of the web page title bar <TITLE>ACTi - Live Demo</TITLE> Line9 : Modify the camera IP address and RTSP port <param value="rtsp:// :7070" name="qtsrc"/> Line18: Modify the camera IP address and RTSP port qtsrc="rtsp:// :7070" Snapshot for Live Demo sample: 11

12 FAQ Q1: I have bandwidth limitation, if the live view is slow, how should I do? You can use snapshot and upload the camera s snapshot to FTP server, then your web page can get file from FTP server directly by the time. ACTi camera supports Event Handler function, it can upload snapshot file to FTP server directly. Or you can select the camera which supports dual stream or multiple streams, then user can use different resolution and frame rate, so the recording will keep on good quality,and the live view can use lower quality to save the bandwidth. Q2: What should I think about when embedding the live view in my website? You may concern some factors 1. Bandwidth limitation on your server site and remote user site. 2. Offer remote user control function on the camera, such as PTZ and record functions 3. Display live view on different browsers, such as IE, Firefox, Safari, Google Chrome. 4. Remote User will use various devices, such as PDA, iphone. Q3: Why I cannot see the image? Please check if there is any firewall to block the video. ACTi cameras send image via two TCP ports, user can configure them from camera s web configurator. If you want to use RTSP protocol, we provide two ways to send video image. One is RTP over UDP, camera will use dynamic UDP port to send image. Second is RTP over TCP (the player site need to have RTSP and RTP over HTTP Tunneling ), camera will use HTTP port to send image. Camera Streaming Type Camera will use the ports TCP TCP Control and Streaming ports (default is 6001 for control and 6002 for stream) RTP over UDP RTSP port and Dynamic UDP port (player site may use RTSP protocol) RTP over UDP HTTP port (player site need to have RTSP and RTP over HTTP Tunneling ) 12
