1. A method of automatically activating an in-car video surveillance system in response to a collision, said method comprising the steps of:
- (a) providing a law enforcement vehicle with an accelerometer having an axis of operation oriented to cause the accelerometer to be responsive to an impact, (b) producing an output signal when said accelerometer senses a predetermined G force indicative of said impact, (c) providing an in-car video surveillance system having a video recorder and a record mode initiated in response to a record command, and (d) delivering said record command to said video recorder in response to said output signal, whereby the video surveillance system records the incident responsible for the impact.

Abstract
An in-car video surveillance system for a law enforcement vehicle is automatically activated in response to a collision. The system is provided with an accelerometer having an axis of operation oriented to cause the accelerometer to be responsive to an impact, and an output signal is produced when the accelerometer senses a predetermined G force. A record command initiates operation of the video recorder of the system in response to the output signal to thereby record the incident responsible for the impact.

3. A method of automatically activating an in-car video surveillance system in response to a collision, said method comprising the steps of:
-
(a) providing a law enforcement vehicle with a first accelerometer having an axis of operation extending generally in the front to rear direction of movement of the vehicle, (b) providing the vehicle with a second accelerometer having an axis of operation extending transversely of said direction of movement, (c) producing a first output signal when said first accelerometer senses a predetermined G force indicative of an impact, (d) producing a second output signal when said second accelerometer senses a predetermined G force indicative of an impact, (e) providing an in-car video surveillance system having a video recorder and a record mode initiated in response to a record command, and (f) delivering said record command to said video recorder in response to at least one of said output signals, whereby the video surveillance system records the incident responsible for the impact. - View Dependent Claims (4)

5. In an in-car video surveillance system:
-
an accelerometer having an axis of operation and adapted to be mounted in a vehicle with said axis oriented to cause the accelerometer to be responsive to an impact, circuitry responsive to said accelerometer for producing an output signal when said accelerometer senses a predetermined G force indicative of said impact, a video recorder having a record mode initiated in response to a record command, and a controller for delivering said record command to said video recorder in response to said output signal, whereby the video surveillance system records the incident responsible for the impact. - View Dependent Claims (6, 7, 8)

9. An in-car video surveillance system for a law enforcement vehicle, automatically activated in response to a collision, said system comprising:
-
an accelerometer having an axis of operation oriented to cause the accelerometer to be responsive to an impact, circuitry responsive to said accelerometer for producing an output signal when said accelerometer senses a predetermined G force indicative of said impact, a video camera for viewing a selected scene, a controller for producing a record command in response to said output signal, and a video recorder having a record mode initiated in response to said record command, whereby the video surveillance system records the incident responsible for the impact. - View Dependent Claims (10, 11, 12)
