ABSTRACT:
A security system for a vehicle which includes an internal compartment which is designed to contain humans. A door is formed within the exterior wall of the vehicle with the door providing access into and out of the internal compartment. A plurality of cameras are mounted within the internal compartment and exteriorly of the vehicle with one camera observing directly the area of the door. The output signals of all cameras are supplied through a multiplexer which causes all the output signals of the cameras to be placed on a single frame of the video camera permitting simultaneous observance of all cameras when the recorded film is observed by a human. When the door is closed, the signals of all cameras are reproduced on the video recorder at a slow playback speed. When the door is open, only the door mounted camera is recorded by the video recorder with sound also being recorded.
