DVS Digital Video Server, referred to as developed in recent years, is Video surveillance equipment, with the development of network technology and broadband network Video monitoring network popularization of traditional Video monitoring will devour the market share of the equipment. Despite the hard disk video recorder (DVR) also has the function of network monitoring, but the mainstream of network monitoring equipment or video server. Video server price will gradually low, many manufacturers offer video server is down again, the fierce competition in the market demand, but also expands gradually. Although many video network security engineering to the server, but still don't know more monitoring project traders use video server for safety engineering, video monitoring project construction. The main network video server centralized in shenzhen, hangzhou manufacturers such as Beijing and the security industry development is relatively fast video server in shenzhen area, and the manufacturer and the application of this technology is based on the relative to other areas. Leading Video server longer names can also be called network video server, it can make the simulation of the video, audio or voice signal into digital signals transmitted through the IP network video server, and network has alarm, yuntai control many auxiliary function. Network video server mainly based on PC software access by or through specific hardware to visit, use the software to visit the CPU is through PC software decoder and display, and the so-called specific hardware is video codecs, video server (when it finished more reasonable video encoder) should be called the function, is contrary to the IP network transmission of digital signal reductive into analog signals, reduction of analog signals through TV wall, monitor equipment to display. With more ways to access or through computer based subdivision here again, two ways, one is B/S structure, one kind is C/S structure, the former through video server browser visit, the latter by client program to visit, the former focuses on video viewing, simple operation, easy to use, while the latter is focused on equipment management, video and other functions, complex operation for multiple functions, but video server management. Based on the video server monitoring, it is a kind of distributed control concept, therefore it has the number of video interface in 1-4, including four video server or 4 road and video encoder and accounted for greater share.

Digital video monitoring products, network is an inevitable trend, video surveillance industry development has proved this trend, network video server monitoring network digital products, and it is an important products in the process of evolution, it is simulated by the camera and IP network with traditional bridge, it is more than the DVR video compression, concentrate on doing video footage of mainframe part to special treatment, easy to form of distributed system structure, a distributed system has been proved to be more flexible than centralized system, therefore, in a sense, video server can replace the current hard disk video recorder. But compared with the network video camera, network integration camera despite no server so high, but it can simulate the matching of network video camera is unmatched types of network video server, at the same time, the video source is not confined to monitor video camera, so using the network server can be derived from various other applications and services. According to the above analysis, we technology based on color million years in video and network technology on the accumulation of WST3000 series of video server, video surveillance area for users in provides an advanced, economical and practical, stability and flexible solutions.

WST3000 series video server using the embedded processor and digital signal processor (DSP) technology, products, mature, stable. Supporting software powerful, based on B/S structure of IE browser visit way, also have based on C/S structure of the centralized management mode, the B/S structure can choose to directly access equipment built-in web server can also pass on to access web management platform video server platform (don't remember every video server address), C/S architecture of the way we can according to management center of video server front quantity provide different levels of management in the program (flexibility, usability, stability of a balanced), all with video server software is free. In addition, our company provides WST3000 series of video codecs, also can achieve IP network video data to simulate data reduction, reduction of video simulation can be connected to monitor, TV wall, matrix, etc.

WST3000 network video server has launched series obtained usercommunities' consistent affirmative, company's powerful r&d strength can according to user requirements for software and change. At present, the products have been widely used in commercial chain, enterprises and institutions, transportation, water conservancy, electric power, telecom, education, military, public security organs, government agencies, etc.

Video decoder is WST3000 series with video encoder supporting the use of WST3000 series, analog signals (video + audio transmission equipment). Video encoder will simulate audio signals, and the additional signals (control, alarm, etc) coding compressed into digital signals, then send into IP network packets packages to Internet, and video decoder is doing the work, it is completely opposite from the IP network access compression, audio data, after decoding reductive into analog signals, video on the video signal for reduction of the output signal is equivalent to monitor video camera, transparent transmission is in that sense. Using IP networks, encoder and decoder, equivalent to the camera output video signals from thousands of kilometers of close to the monitoring center. For ordinary network monitor may not need video codecs, but for large-scale monitoring system, using video codecs can realize signal and matrix or TV wall of connection.

WST3000 series video codecs, based on the single plate design of industrial structure, the solution of embedded signal compression by a powerful DSP, special operation embedded real-time OS Linux, after strict high low temperature, vibration, high efficiency and stability and performance monitoring service, providing industrial-class.
