US Patent 7355629 Internally mounted, movable camera for vehicles

A camera assembly for a commercial vehicle with a cargo compartment, which comprises a camera, and a movement apparatus, wherein the movement apparatus displaces the camera, at least partially outward, from the interior of the cargo container, in such a manner, that the camera, by an energized movement apparatus can survey a definite field of view in the rearward area of the commercial vehicle. The movement of the camera may be through an opening in the rear closure of the cargo container. In this way, it becomes possible, even with a downward, closed, rear to observe the area lying behind the commercial vehicle by means of the camera during the backing up of the commercial vehicle.
