Heating and cooling of a mobile video recorder
First Claim
1. A mobile video recording apparatus, comprising:
- (a) input means for inputting a video signal;
(b) compression means for compressing the video signal input by said input means;
(c) recording means for digitally recording the compressed video signal;
(d) chassis means for enclosing said input means, said compression means and said recording means;
(e) mounting means for fixedly attaching said chassis means to a surface of a vehicle;
(f) heating/cooling means for attaching to said chassis means and for heating and cooling an interior of said chassis means, wherein said heating/cooling means comprises a solid state heat pump;
(g) temperature detection means for sensing a temperature inside said chassis means and outputting a temperature signal; and
(h) control means for controlling said heating/cooling means based on the temperature signal.

Abstract
Provided is a mobile event-recording device contained within an airtight chassis with its internal temperature regulated according to pre-programmable operational thresholds via a controller using a temperature sensor and a solid-state heat pump attached to or proximate with the chassis. The mobile event-recording device further includes multiplexors, compressors and a buffer for the temporary storage of video signals during a sliding time window for the recording of compressed digital video and audio onto a hard disk or other high-capacity long-term storage medium. With regard to the buffer, the device responds to receipt of a trigger signal by initiating live recording of the video signal by the video recorder and transferring the temporarily stored video signal to the storage means (or otherwise preserving the temporarily stored video signal for permanent storage).
