<P> A red light camera ( short for red light running camera ) is a type of traffic enforcement camera that captures an image of a vehicle which has entered an intersection in spite of the traffic signal indicating red ( during the red phase ) . By automatically photographing vehicles that run red lights , the photo is evidence that assists authorities in their enforcement of traffic laws . Generally the camera is triggered when a vehicle enters the intersection ( passes the stop - bar ) after the traffic signal has turned red . Typically , a law enforcement official will review the photographic evidence and determine whether a violation occurred . A citation is then usually mailed to the owner of the vehicle found to be in violation of the law . These cameras are used worldwide , in countries including : Australia , New Zealand , Canada , the United Kingdom , Singapore and the United States . If a proper identification can not be made , instead of a ticket , some police departments send out a notice of violation to the owner of the vehicle , requesting identifying information so that a ticket may be issued later . </P>
