Abstract
A plurality of video cameras each send a video signal and an audio signal to a video controller. Each of the video cameras receive a vertical drive signal and a horizontal drive signal from the video controller. A sensor interface sends sensor signals to the video controller. The video controller sends camera status signals to camera status indicators which indicate which of the video cameras are active. The video controller determines which of the video cameras are active, selects the video signals from one of the plurality of cameras, inserts a camera number code into the selected video signals which corresponds to the selected video camera, inserts indicator symbology into the selected video signals which represent the information from the status interface, and sends the selected video having the camera number code and the indicator symbology to a video recorder.
