Intelligent IP camera system design considerations

IP surveillance is a digitized and networked version of closed-circuit television (CCTV). In an IP surveillance system, an IP camera records video footage and the resulting content is distributed over an IP (Internet protocol) network.?
Since LS Vision paid a visit to Bangladesh the early of November, and knew intelligent analysis gained a big market, we attached great importance and energy on it. IP surveillance networks are becoming more and more "intelligent," and more of the intelligence is moving beyond the central control and monitor center to the camera nodes with every product generation. This intelligence offers advantages over the centralized approach by enabling the distributed camera nodes to detect situations, zoom, pan, and scale the surveillance image based on rules set up for each node. This on-camera information can then be shared with the central monitor and with other nodes.
Various video analysis algorithms, such as object detection and tracking, intrusion detection, and audio analysis algorithms such as specific sound detection and location, are beginning to take hold across the full range of video surveillance technologies. This distribution of intelligence directly impacts the performance levels of the local camera's processors, which must have excellent support for media processing, including audio/video compression and specialized analytics algorithms for event detection, tracking, etc.
