1. A video system for a law enforcement vehicle, the system comprising:
- a video camera mounted on the vehicle and operable to capture and encode video for law enforcement applications and to stamp the encoded video with an unalterable unique camera identifier,wherein the video captured and encoded by the video camera is stamped with the camera identifier to verify and secure an identity of the camera on the video;
a central control unit mounted on the vehicle and operable to receive and decode the encoded video;
a rear view mirror housing;
a mirror mounted in the rear view mirror housing;
a display monitor operable to display the decoded video, the display monitor being mounted in the rear view mirror housing substantially behind the mirror, and the mirror and the display monitor being configured so that the displayed video is viewable through the mirror;
a memory for receiving and storing the captured and decoded video from the central control unit;
a microphone operable to capture and encode audio, wherein the central control unit is operable to receive and decode the encoded audio;
a vehicle interface box mounted on the vehicle and operable to interface an external device to the central control unit, wherein the external device is a radar gun;
a co-processing module mounted on the vehicle and operable to provide processing for an additional feature of the system, wherein the additional feature is selected from the group consisting of a face recognition feature and a license plate recognition feature; and
a recorder operable to make a copy of the captured and decoded video stored in the memory.

Abstract
A vehicle-mounted system (1010) for recording video and audio. The system (1010) uses distributed processing, including encoding the video and audio at their source(s), and a high-speed, e.g., Ethernet, bus (1148) connecting the various system components and external devices. The system (1010) may include a display monitor (1040) which is integrated into the same housing (1020) as a rear view mirror (170) of the vehicle, with the display monitor (1040) being located behind the mirror (170) and video displayed on the monitor being visible through the mirror (170).

17. A video system for a law enforcement vehicle, the system comprising:
-
a rear view mirror housing; a mirror mounted in the rear view mirror housing; a video camera mounted on the vehicle and operable to both capture and encode video for law enforcement applications and to timestamp and store the encoded video; a central control unit mounted on the vehicle and operable to receive, decode, and timestamp the encoded video; a memory for receiving and storing the captured, decoded, and timestamped video from the central control unit, wherein timestamps from the video camera and the central control unit are synchronized, such that a video frame lost during transmission from the video camera to the central control unit can be retransmitted and integrated with the decoded video received and stored by the central control unit; a recorder operable to make a copy of the captured, decoded, and timestamped video stored in the memory, wherein the recorder is selected from the group consisting of a CD burner and a DVD burner; and a display monitor operable to display the decoded video, the display monitor being mounted in the rear view mirror housing substantially behind the mirror, and the mirror and the display monitor being configured so that the displayed video is viewable through the mirror; a microphone operable to capture and encode audio, wherein the central control unit is operable to receive and decode the encoded audio; a vehicle interface box mounted on the vehicle and operable to interface an external device to the central control unit, wherein the external device is a radar gun; and a co-processing module mounted on the vehicle and operable to provide processing for an additional feature of the system, wherein the additional feature is selected from the group consisting of a face recognition feature and a license plate recognition feature. - View Dependent Claims (18, 19, 20)
