Hard Disk Mobile DVR (Automotive) is a cost-effective, multi-functional device designed for 
video surveillance and remote monitoring of your mobile assets. 
It uses a high-speed processor, an embedded Linux platform, and the most advanced technology 
in the IT field, such as H.234 Video Compression/Decompression,3G/4G network transmission 
technology and GPS positioning technologies. MDVR can realize four/eight channel video recording. 
Each channel support CIF, HD1 and D1 image solution. Drivers’ driving information, GPS data 
and alarm data are recorded in Hard Disk which is used as the storage medium. The MDVR may 
look simple in its exterior design, provides powerful auto black box features, installation flexibility 
and high reliability.

The MDVR Application Connection Diagram: 
This product can be used for video surveillance and remote monitoring, suitable for general or special vehicles such as buses, logistics vehicles, trucks, coaches, taxis, tanker, cars, school buses, police, patrol cars. In front of it is mainly collected by special car camera video signal is then passed through a special video cable to the MDVR hosts do video compression and image processing, which is stored locally on the SD card. It can also be remote monitoring or remote video recording and download the remote client, if the 3G/4G mode. It can locate the position of the vehicle in real time. Figure 1-1 is a schematic diagram of the next ordinary mode applications, the actual process of using each function will vary with the presence of the module.
