Mobile digital video monitoring with pre-event recording
First Claim
1. An apparatus for monitoring events on a public transportation vehicle, 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 in a vehicle at a first location and is oriented so as to detect scenes within 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 in 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 in the vehicle;
(d) buffer means for receiving and storing the video signal so as to preserve the video signal during a sliding time interval, wherein the second location is different than the first location and is different than the third location, 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 are systems and techniques for monitoring events on a transportation vehicle, in which camera means provides in real time a video signal that corresponds to an observed live-motion scene, is mounted in a vehicle at a first location and is oriented so as to detect scenes within the vehicle. Trigger means, positioned at a second location in the vehicle, provides a trigger signal to begin recording of the video signal. Video recording means mounted at a third location on the vehicle receives the video signal and records the video signal in response to the trigger signal. Buffer means receives and stores the video signal so as to preserve the video signal during a sliding time interval. The first location, second location and third location are all different, and 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.

15. An apparatus for monitoring events on a public transportation vehicle, 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 in a vehicle and is oriented so as to detect scenes within the vehicle;
(b) trigger means for providing a trigger signal to begin recording of the video signal;
(c) video recording means for receiving the video signal provided by the camera means and recording the video signal, wherein said video recording means is mounted in the vehicle;
(d) buffer means for receiving and storing the video signal so as to preserve the video signal during a sliding time interval, wherein the video recording means records the video signal at a low frame rate for permanent storage and at a high frame rate into said buffer means, 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 and the video recording means begins recording the video signal at the high frame rate for permanent storage. - View Dependent Claims (16, 17, 18)
