A system and method for continuous recording of an integrated data stream from audio, video, and sensor devices from a digital video recording system installed within a mass transit vehicle. The digital video recording system contains a covert camera and timers that initialize data recording after the ignition is turned off within a vehicle, when acts of vandalism destroy or obscure the data stream from visibly mounted cameras, or when motion is detected within the vehicle where there should be none. The invention includes timers that may be set for known periods of time, or set to progressively extend recording as needed.
