Design and realization of digital video surveillance system for power substation

With the booming development of power substation automation,especially of unattended power substation,digital video surveillance systems are applied widely. But most of them are lack of serious consideration for power system features. A new design of digital video surveillance system is presented for power industry. Its basic structure and functional features are described. It adopts key techniques,such as hardware compression,IP multicast,hierarchical service,hybrid programming and so on. It has simple structure,flexible configuration and enhanced functions,which improves the system availability and creates excellent conditions for data sharing and information integration.
