Automatic activation of an in-car video recorder using a vehicle speed sensor signal
First Claim
1. An activation controller for automatically activating an in-car video system that includes a car-mounted camera and video recorder, comprising:
- an input for receiving a vehicle speed sensor signal that is indicative of a speed of a vehicle in which the in-car video system is installed;
a comparator for comparing the speed of the vehicle against an activation threshold;
an alarm generator coupled to the comparator for generating an alarm signal if the speed of the vehicle exceeds the threshold; and
an output for transmitting the alarm signal to a trigger input of the in-car video system so that the video recorder is activated into the record mode of operation upon receiving the alarm signal.

Abstract
An in-car video system and method are provided where a vehicle speed derived from a vehicle speed sensor (“VSS”) signal is compared against a user-settable threshold value. If the vehicle speed exceeds the threshold value, an alarm is generated. The alarm is used by the in-car video system to automatically activate the record function of a video recorder. The alarm may be optionally sent to a remote location, such as a police agency'"'"'s headquarters as an alert that the vehicle speed has exceeded a set threshold and that a possible high speed pursuit has commenced. Vehicle speed information derived from the VSS signal is generated into a form that is continuously displayable on an in-car video monitor or continuously recordable by the video recorder along with the video and audio information captured by the in-car video system camera and microphones.

10. A method of operating an in-car video system including a car-mounted camera and video recorder that is installed and operated in a vehicle, the method comprising the steps of:
-
receiving a vehicle speed sensor signal that is indicative of a speed of the vehicle; and activating the in-car video system into a record mode of operation if the speed of the vehicle exceeds a threshold speed so that a video image captured by the car-mounted camera is recorded by the video recorder. - View Dependent Claims (11, 12, 13, 14, 15)

16. An in-car video system, comprising:
-
a video recorder mountable in a vehicle and arranged to be coupled to a camera mounted in a vehicle so as to receive video captured by the camera; and a controller that is arranged to be coupled to receive a signal from a vehicle speed sensor mounted in the vehicle, the signal being indicative of speed of the vehicle, for triggering the video recorder into record mode when the speed of the vehicle exceeds a threshold speed. - View Dependent Claims (17, 18, 19, 20)
