Abstract: A system including a surveillance system that receives compressed video from a plurality of network video cameras and a traffic control subsystem of the surveillance system further including a first processor of the subsystem that monitors for and detects the number of I-frames per time period received from each of the plurality of video cameras, a second processor of the subsystem that compares the number of received I-frames with a threshold value and detects that one of the plurality of network cameras has exceeded the threshold value and a third processor that sends a control message to the one of the plurality of network cameras adjusting a time interval of I-frames from the one camera based upon the comparison.
