  • Patent number: 9591230
    Abstract: Systems and methods for reducing or substantially eliminating image flicker are provided. The method includes capturing a frame from a video data stream from a monitored region at a frame capture rate wherein the monitored region is illuminated by a lighting system with a predetermined cycle variation, determining a minimum common multiple of the frame capture rate and the cycle variation, determining a number of frames captured within the determined minimum common multiple of the frame capture rate and the cycle variation, and measuring accumulation at a multiple of the determined number of frames. Measuring the accumulation at a multiple of the determined number of frames substantially eliminates image flicker in the video data stream.

  • Publication number: 20150312651
    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.
