Abstract
A method and apparatus for monitoring the operation of a motor vehicle for the purposes of determining causation and fault in the event of an accident, and to enhance physical security of the vehicle utilizes electronic digital cameras strategically placed to obtain sequential images of the area immediately adjacent the exterior, and optionally the interior, of the vehicle and to record those images in an electronic memory. A command module controls operation of the cameras and changes the camera mode of operation in the event of an impact or rapid inertial change that signals a collision or other traumatic event.
