Abstract:

In heterogeneous network environments, signaling control protocols used by various subsystems with different technology systems and interfaces are very difficult to be unified for constructing remote distributed integrated video surveillance system, which can bring very big puzzle to networks interconnection. Therefore, a framework based on SIP architecture was proposed. By using the core next generation network control protocol SIP, its extension method based on event notification mechanism, and XML extension to SIP message body, system deployment and expansion flexibility can be improved, video surveillance ubiquitous business integration can be achieved, and various remote communication and control operations of distributed nodes can be unified and simplified.

Key words: ubiquitous network;SIP protocol;video surveillance;event notification
