This product can be used for video surveillance or remote monitoring which applies in common or special vehicles such as buses, logistic vehicles, trucks, long-distance coaches, taxis, tankers, cars, school buses, police cars, patrol cars. In front-end it mainly collects video signal by dedicated automotive camera, then transmits to the MDVR host via a special video cable to do the video compression and image processing, which is locally storage in SD card.

It can also be remote monitored or remote video recorded and downloaded by the remote client if with 3G models. It can real-time locate the vehicle position; Figure 1-1 schematic diagram is a common mode of application, each function during actual use will vary with the presence of module.
