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.
