The system has studied in this article adopts the advanced embedded video server or the hard disk video cassette recorder on the hardware and the multi-business database technology on the software , it follows Brower/Server (the browser / the server ) architecture , totally accords with the communication standard of the international digital video. The system is on the basis of public network or the network platforms of enterprises and institutions such as the network of the Department of public safety mentioned in the article. The advantage of resource-sharing is fully played in this system, necessary picture and controls can be transferred in real time according to the needs of different departments and such multiple functions as data gathering, video can be supported well. Meanwhile, the system strengthens the function of safety management too, make sure that users can guarantee the security of the data in using.The system fully satisfy the realistic needs of the detention house of Hunan Province , and it has referential value for the similar projects and items .
