Vehicle-mounted video system with distributed processing
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.

10. The video system as set forth in claim 1 , wherein one or both of the first and second video cameras is configured to be placed in a stealth mode, such that all lights and indicators on the respective video camera are turned off.
11. The video system as set forth in claim 1 , wherein the system is configured to be remotely controlled by a remote control device.
12. The video system as set forth in claim 1 , wherein the central control unit is communicatively coupled with at least one of a crash sensor, a radar gun, and a speedometer.
13. A video system for a vehicle, the system comprising:
a first video camera mounted on the vehicle and configured to capture and encode video and to stamp the encoded video with a first unique camera identifier;
a second video camera mounted on the vehicle and configured to capture and encode video and to stamp the encoded video with a second unique camera identifier;
wherein the first video camera and the second video camera are configured to implement a pre-event recording loop;
a central control unit configured to receive and decode the encoded video from the first camera and the second camera,
wherein one or both of the video captured by the first video camera and the video captured by the second video camera is selectively playable on a display of a smartphone carried by a user of the video system, such that the display is configured to display the selected decoded video; and
a microphone configured to capture and encode audio, wherein the central control unit is configured to receive and decode the encoded audio.
14. The video system as set forth in claim 13 , wherein one or both of the first and second video cameras is synchronized with the central control unit so as to provide an accurate time stamp associated with the respective captured video.
15. The video system as set forth in claim 13 , wherein the first and second video cameras and the central control unit are connected by a high speed bus.
16. The video system as set forth in claim 13 , wherein the first and second video cameras are connected to a hub, the hub is connected to the central control unit, and the central control unit is configured to receive the video from each of the first and second video cameras simultaneously.
17. The video system as set forth in claim 13 , further including a location determining device configured to determine a location of the vehicle when the video from the first and second cameras is captured, and wherein the memory of the video system is configured to record at a least a portion of the captured video from the first and second cameras and the location of the vehicle when the video from the first and second cameras was captured.
18. The video system as set forth in claim 17 , wherein one of the first and second video cameras includes an input that when actuated, marks a current location of the respective first or second video camera in the captured video.
