Video Surveillance System security has become all walks of life an important part of the system, it is a comprehensive prevention system capability. With the computer, networking and image processing, the rapid development of transmission technology, video surveillance technology has come a long way development. video storage, image acquisition, compression codec of video surveillance systems are key.

WEB-based Network Video Monitoring System

At present, network-based Digital Video Surveillance System Video Surveillance System is the mainstream of development, and as microprocessor technology, computer network technology, WEB-based network video surveillance system has been gradually people's extensive attention, the main The principle is: the use of embedded video server embedded real-time operating system, built-embedded WEB server, from the camera to send video signals compressed by the high efficiency compression chip through an internal bus to the built-in WEB server. Users can monitor the client directly through the WEB server browser watch video images on the camera, authorized users can control the PTZ camera lens action. Monitoring system described in this paper, the schematic diagram shown below.

Commonly used in embedded video server is the network of video servers, such as WST3004 4 video encoder and TIANDY TC-NS621 single D1 network video server, real-time operating system, embedded Web services to support IE browsing, configuration, upgrade.

HMIBuilder support IE browser

The IE browser HMIBuilder elements embedded in the View page views for HTML support. For some video equipment to support the monitoring from a remote to navigate the screen, use the graphic element can be integrated directly into screen HMIBuildr system.

Network video server, for example HMIBuilder test

HMIBuilder control of the IE through the test series TIANDY T network monitoring products, the realization of the configuration of the video surveillance software.
Test steps:

1. Physical connection
2. Video equipment to the network access to your network or crossover cable to connect directly to PC.
3. 75Ω coaxial cable with standard network video server and BNC video input port
4. Cameras connected to video output.
5. Cameras connected to video servers and network power supply (DC 12V).
6. Network under normal circumstances in orange network within five seconds and flashing lantern light, physical connection to complete.
7. IE settings

If this is the first time the use of T Series network video products, you need to download ActiveX controls, download the pre-IE browsers need to set up appropriate controls to ensure that the download was successful. Note: Use the Windows operating system built-in IE browser, to ensure that the version 6.0.
Open the IE browser, then click on "Tools" - "Internet Options" - "security" - "Internet" - "Custom Level" (Figure 3.1).

Will be "safe" - "Local Intranet" - "Custom Level", the ActiveX controls and plug-ins of the project all set to Enable.

If you are using the operating system to Windows XP, you need to in the "trusted sites" will be the network video equipment added to the IP address (Figure 3.3): "security" - "site" - enter the IP address, server authentication cancellation -- "Add" - to determine.

1. HMIBuilder control of the IE settings and configuration monitoring the effect of

Control by double-clicking the right mouse button menu or select the graphic element attributes, open the IE browser control's properties. Network in the URL field enter the IP address of video equipment.

Note: in the registry before the need to ensure that the PC and network IP address of video equipment in the same network segment: If the PC-http://10.10.30.234, network video equipment for http://10.10.30.233.
When running after HMIBuilder, such as whether you are prompted to download the control, click "Yes", wait a moment you can successfully download the control, there's Web video equipment monitoring screen. Landing window on the right to enter a user name and password: Admin / Admin (case sensitive), click connect, wait a successful connection to the screen.
