The DC-1 is a car black box video recorder. It records video and audio on a constant loop and stores it on a standard SD memory card. This camera is fitted with a 3D sensor which measures G-force and will detect an impact. In the event of a collision,  harsh braking or acceleration the DC-1 will save a 20 second clip (10 seconds before and 10 seconds after the incident) as an “event”. The supplied 4gb card can hold over 200 “events”
