Design And Realization Of Network Video Surveillance Based On Embedded System

Combined with network technique, embedded system technology which is developing rapidly brings many applications, including network video surveillance based on embedded system. The key to implement video surveillance system based on network is a kind of embedded equipment. It can collect video data and transfer the data through network. In this paper, CBTVIEW, be named of this system, will be developed to make this function come true.Combining embedded development technology with Internet technology, this paperhas realized remote image surveillance and control system based on embedded Linux. The web server program runs under the embedded Linux system platform which adopts ARM-kernel S3C2410 as its CPU and acts as Server role in the whole system. It runs by means of backstage and waits for Clients'request by browser tools.Firstly, this paper briefly introduces the system's realization scheme, then presents characteristic of the embedded system development. Secondly, discusses how to build the evironment of the embedded system development and USB digital camera driver realization under Embedded Linux. Then explains especially how to use Video4Linux API functions to realize video gathering, elaborates the concrete realization course and way of network communication. Lastly, focuses the building of Embedded Web Server and realizes the network surveillance based on B/S mode. Moreover also integrates in the system to control the pan\tilt, expandes the monitor area.Finally, in the lab circumstance, eperiment result shows that the system realizes the fuction of remote surveillance in LAN and reaches the predetermined target.
