ABSTRACT:
A system which retrofits to an existing surveillance system and cooperates with sensors, video cameras and video monitors of the existing surveillance system. The system comprises a plurality of processing boards having a substantially similar architecture. Several frame grabber/frame storage processing boards are provided, each of which digitize the analog video signals from the video cameras and stores the digital data in a solid state buffer memory. Several display boards are provided to display the digitized video data on display monitors. A controller board controls the exchange of video data and command or control messages over a video link and between processing boards, respectively. Additional expansion boards may be added to support additional buffering and system options. Each processing board is built around a parallel processing computer chip.
