Automatic activation of an in-car video recorder using a vehicle speed sensor signal |
摘要 |
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.
