Design And Implementation Of Network Video Surveillance Image Access Software System

This project mainly studies about the development and application of image access systems in video surveillance system. This thesis reviews the present situation and prospect of video surveillance system。First, it introduces the development, characteristic and application of network video surveillance system. Second,it elaborates the relevant technology to the design of video surveillance system technology,describes a variety of digital video transmission protocol, and introduces three kinds of standard of Numeral video information code and compression:JPEG,H.264,MPEG. And then mainly introduces the design process of image access software and the overall structure and function of the system in the network video surveillance process and.With the popularity of broadband network, the network video surveillance gradually developed from a local monitoring to remote monitoring, and appeared remote network video surveillance system which on behalf of a network video server.Network Video Server solves the video stream transmission problems on the network, begins processing and transmission of digital from image acquisition, this allows more diversity in the choice of transmission line. As long as there is a network of local, the image transmission would be possible; the whole system would tend to be intelligent. Many Internet companies have started to step in the development of such video surveillance systems.The video surveillance network will later have a better extension. For example, the analog video surveillance program needs to increase the DVR or matrix in the extended time. But the network video monitoring solutions can be easily extended with the increase of the appropriate cable IP,and a corresponding increase in the management of the server settings only. Another advantage is that storage. It needs to create great storage platform if the Analog video surveillance system is put in a monitoring center, but the network video monitoring system can complete the information stored video recording by the distributed storage.Combining with the collection of data and the understanding of related technologies, through the development and research in image of Integrated Access System, to discover, analyze and solve problems, continuously experiment, improve, try, eventually developed a Web-based all-digital information transmission and management systems, and used in video surveillance systems.
