Mobile digital video recording with pre-event recording
First Claim
1. An apparatus for mobile event recording, said apparatus comprising:
- (a) camera means for providing in real time a video signal that corresponds to an observed live-motion scene, wherein said camera means is mounted on a vehicle at a first location and is oriented so as to observe scenes outside of the vehicle;
(b) trigger means for providing a trigger signal to begin recording of the video signal, wherein said trigger means is positioned at a second location on the vehicle;
(c) video recording means for receiving the video signal provided by the camera means and recording the video signal in response to the trigger signal, wherein said video recording means is mounted at a third location on the vehicle; and
(d) buffer means for receiving and storing the video signal so as to preserve the video signal during a sliding time interval, wherein the first location, second location and third location are all different, and wherein in response to provision of the trigger signal at least a portion of the video signal stored in the buffer means is preserved for recording by the video recording means.

Abstract
Provided is a mobile event-recording device that includes distributed elements within, attached to or otherwise mounted to a mobile vehicle, with the principal elements being: a first camera providing a real-time video signal that corresponds to an observed outboard live-motion scene; and a digital video recorder receiving the video signal provided by the camera and recording the video signal in response to a trigger signal (e.g., an activation switch for a light bar or siren, an air bag sensor signal indicating air bag deployment, or depression of an emergency button or a dedicated recording activation switch). The video recorder uses a buffer to receive and store the video signal so as to preserve the video signal during a programmable sliding (or rolling) time interval prior to the triggering event. Thus, in response to provision of the trigger signal, at least a portion of the video signal stored in the buffer is preserved for recording by the video recorder on a hard disk (or other long-term storage medium) and thereafter, the video recorder records directly on the hard disk (or other long-term storage medium).
