Abstract

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

Claims

1. A video system for a vehicle, the system comprising:

a video camera mounted on the vehicle and operable to capture and encode 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;

a memory port adapted to receive a removable memory module, wherein the removable memory module is operable to receive and store the captured and decoded video from the central control unit;

a central control unit housing, wherein a key is required to remove any removable memory modules housed therein;

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; and

a microphone operable to capture and encode audio, wherein the central control unit is operable to receive and decode the encoded audio.

2. The video system as set forth in claim 1, wherein the video system is operable to implement a pre-event recording loop.

3. The video system as set forth in claim 1, wherein the video camera and the central control unit are connected by a high speed bus.

4. The video system as set forth in claim 1, wherein the central control unit housing is vented.

5. The video system as set forth in claim 1, wherein the rear view mirror housing is vented.

6. The video system as set forth in claim 1, wherein there are two or more video cameras connected to a hub, the hub is connected to the central control unit, and the central control unit is operable to receive the encoded video from each of the two or more video cameras simultaneously.

7. The video system as set forth in claim 1, further including a location determining device operable to determine a location of the vehicle when the video is captured, and wherein the memory of the video system is operable to record at a least a portion of the captured video and the location of the vehicle when the video was captured.

8. The video system as set forth in claim 1, having at least one software component for implementing the functionality of the system, wherein said at least one software component of said system is upgradable while said system is located in the field as during normal use of the system.

9. The video system as set forth in claim 8, wherein an upgrade of said at least one software component is performed by use of an external device adapted to interface via a wired connection with said video system.

10. The video system as set forth in claim 8, wherein an upgrade of said at least one software component is performed by use of an external device in wireless communication with said video system.

11. The video system as set forth in claim 1, the video system being adapted to communicate wirelessly with an external computing device, wherein the external computing device is selected from the group consisting of a PDA, a smartphone, and a laptop.

12. The video system as set forth in claim 1, wherein at least one of said video camera, central control unit, or display monitor comprises a backup power source for operating said video camera, central control unit, or display monitor in the event a primary power source is lost.

13. The video system as set forth in claim 12, wherein the backup power source is a battery.

14. A video system for a vehicle, the system comprising:

a video camera mounted on the vehicle and operable to capture and encode video and to stamp the encoded video with a unique camera identifier;

a central control unit mounted on the vehicle and operable to receive and decode the encoded video;

a memory port adapted to receive a removable memory module, wherein the removable memory module is operable to receive and store the captured and decoded video from the central control unit;

a central control unit housing, wherein a key is required to remove any removable memory modules housed therein;

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; and

a microphone operable to capture and encode audio, wherein the central control unit is operable to receive and decode the encoded audio.

15. The video system as set forth in claim 14, wherein the video camera is synchronized with the central control unit so as to provide an accurate time stamp associated with the video.

16. The video system as set forth in claim 14, wherein the video system is operable to implement a pre-event recording loop.

17. The video system as set forth in claim 14, wherein the video camera and the central control unit are connected by a high speed bus.

18. The video system as set forth in claim 14, wherein the central control unit housing is vented.

19. The video system as set forth in claim 14, wherein there are two or more video cameras connected to a hub, the hub is connected to the central control unit, and the central control unit is operable to receive the video from each of the two or more video cameras simultaneously.

20. The video system as set forth in claim 14, further including a location determining device operable to determine a location of the vehicle when the video is captured, wherein the memory of the video system is operable to record at a least a portion of the captured video and the location of the vehicle when the video was captured.

21. The video system as set forth in claim 14, having at least one software component for implementing the functionality of the system, wherein said at least one software component of said system is upgradable while said system is located in the field as during normal use of the system.
