ABSTRACT:
A system and method for viewing and controlling a plurality of digital video recorders (DVRs). The system includes a video matrix switch comprising a plurality of inputs and outputs arranged as a matrix; a plurality of cameras and a plurality of DVRs having ports in communication with the plurality of inputs of the video matrix switch; a plurality of monitors attached to the plurality of outputs of the video matrix switch; a controller that is adapted for communication with at least one port of each of the DVRs, the controller also communicates with the video matrix switch and provides a mapping function between the DVRs and video matrix switch inputs and outputs. The controller may comprise a computer that communicates with the plurality of DVRs via an Ethernet Switch, and the computer communicates the route DVR commands to the appropriate DVR of the plurality of DVRs. By use of a table, the computer can reroute video images to backup DVRs in the event of a failure.
