Abstract

The present invention relates to systems and methods for combining video data to optimize video performance for use with distributed multiple video monitoring systems. One embodiment of the present invention relates to a computer controlled surveillance system including distributed multiple real-time video display. The system includes a local data transmission system, a global data transmission system, a plurality of video capture devices, a control module, and a client module. The control module includes a combination module configured to generate a combined video data signal including a data combination of the plurality of video devices. The combined video data signal includes independently identifiable simultaneous representations of each of the video data signals packaged so as to posses a transmission bandwidth equal to approximately that of one of the video data signals. The client module is configured to display the combined video data signal.
