A Scalable intelligent service model for video surveillance system based on RTCP

As an extensible signaling protocol, RTCP protocol can be applied in developing video surveillance system. Traditionally, for RTP-based centralized video surveillance system, surveillance scale is limited by both the capability of surveillance server and the availability of bandwidth. This paper focuses on how to keep surveillance capability when the number of video surveillance system increases. Based on the study of the RTCP Protocol, we analyze the drawback of the existing video surveillance system model, and propose the scalable service model for video surveillance system. By this model, the extra service requests can be transferred and served in the cooperated video servers. The paper presents the video surveillance control policy of the model in detail. We developed a prototype of video surveillance system based on above model. Experimental result show the service model works well.
