Method and apparatus of controlling a plurality of video surveillance cameras

摘要

An apparatus, a method, and a software product to control a plurality of surveillance video camera/encoder combinations. The method includes receiving a plurality of encoded video streams from a respective surveillance camera/encoder combination, and accepting a measure of the level of activity for each encoded video stream. Each measure is obtained from the output of the camera of the corresponding camera/encoder combination. The method further includes assigning output bit rates for each encoded stream according to the accepted level of activity such that a maximum overall bit rate is not exceeded. One version is for controlling camera/encoder combinations that accept remote bit rate control, and a second is for controlling camera/encoder combinations that send at a pre-set bit rate. One version includes a network connection between the camera/encoder combinations, and the method or apparatus for central control.
