Abstract

A compact speed measurement system for field or onsite use in measuring speeds of vehicles and capturing images of select vehicles. The system includes a laser speed detector for determining a speed of a vehicle in a specific target area. When a speed is determined, the detector generates a speed signal. The system includes a camera generally aligned with the speed detector operable to capture and store digital still images of vehicles in memory. The camera is programmed to respond to an image capture signal to generate and transmit a digital image file including a still image of the vehicle targeted by the detector. A portable field processor is communicatively linked to the speed detector and the camera to first receive the speed signal, to process the speed signal and to transmit an image capture signal to the camera, and to receive the digital image file from the camera.
