Abstract
A digital video surveillance system for a law enforcement vehicle comprises a video camera mounted on the law enforcement vehicle and positioned to view an incident. A memory buffer records video signals from the video camera. A controller generates record and playback signals to record and to display the video signals. A digital video recorder is responsive to the record signal to record the video signals from the memory buffer on an optical medium and to the playback signal to reproduce video signals recorded on the optical medium. A vault encloses the digital video recorder. A battery provides backup power to the digital video surveillance system. The optical medium may be a DVD disk. A watermark may be included with the digital recording.

12. A digital video incident capture system for a law enforcement vehicle comprising:
-
a video camera for generating video signals of an incident, said video camera mounted on said law enforcement vehicle and positioned to view said incident;
a wireless microphone adapted to be worn by an operator of said law enforcement vehicle, said wireless microphone generating a radio signal modulated by received audio communications;
a receiver responsive to said radio signal for generating electrical signals corresponding to said audio communications received from said wireless microphone;
a controller for selectively generating record and playback signals to record and playback said video signals and said electrical signals corresponding to said audio communications;
logic circuitry for combining said video signals and said electrical signals into a composite signal;
a memory buffer for continuously storing said composite signal;
a digital video recorder having a DVD drive and responsive to said record signal from said controller to record said composite signal from said memory buffer on a DVD disk, said recorder responsive to said playback signal to reproduce said composite signal recorded on said DVD disk;
a display selectively responsive to said video signals generated by said video camera and said video signals of said composite signal reproduced by said digital video recorder to display a video image; and
a speaker mounted in said law enforcement vehicle responsive to said electrical signals generated by said receiver and said electrical signals of said composite signal reproduced by said digital video recorder. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A digital video surveillance system for a law enforcement vehicle comprising:
-
a video camera for generating video signals, said video camera being mounted on said law enforcement vehicle and positioned to view an incident;
a history buffer for continuously recording said video signals from said video camera to provide a video history of predetermined duration;
a controller for selectively generating a record signal and a playback signal;
a digital video recorder having a disk drive and responsive to said record signal for receiving and recording said video history on an optical medium and for receiving and recording ensuing video signals from said history buffer, and responsive to said playback signal for reproducing video signals recorded on said medium; and
