Abstract:
A video surveillance system includes a plurality of video sources, at least one processing server in communication with the video sources, and at least one monitoring station viewing video from the video sources. The video sources are distributed over a target area to be monitored by the surveillance system and are attached to a video network. The processing server allocates bandwidth to the video sources with an accuracy function which provides event/object detection accuracy as a function of image/video quality transferred over the network. The image accuracy is the accuracy with which the processing server identifies features in a video image. Bandwidth is allocated by optimizing the overall event/object detection accuracy by adjusting image/video quality for each video source optionally subject to the dynamic network conditions experienced by each video source.
