Traffic enforcement system with time tracking and integrated video capture

摘要

A method, system, and apparatus are provided for capturing a video image and speed of a target vehicle. A ranging device detects a distance to a target vehicle. The focal distance or zoom of a video camera is set and adjusted based on the distance. The speed of travel of the vehicle is detected, displayed, and/or stored in association with a video image captured of the vehicle by the video camera. A range of distances within which to capture the video image and speed of the vehicle may be set by detecting distances between a pair of landmarks or using GPS and compass heading data. An inclinometer is provided to aid initiation of a power- conservation mode. A target tracking time may be determined and compared to a minimum tracking time period. A device certification period can be stored and displayed and the device deactivated upon expiration thereof.
