The so-called on-vehicle DVR adopts the standard structure of 1U, which is installed at the location of the radio or CD player of the bus, and accesses 1-4 channels of images to monitor and record the situation in the vehicle. The compression algorithm currently used in on-vehicle DVRs Mainly MPEG4 and H.264.

Manufacturers have a nice name for this embedded DVR used in the car, MDR or MVR (MobiLEDigitalrecorder or Mobilevideorecorder). Therefore, "Mobile (mobile)" has become the biggest difference between car DVR and ordinary DVR. It is precisely because the vehicle-mounted DVR has such mobility that it provides good conditions for the safety monitoring of the vehicle during the movement.

Can ordinary surveillance DVRs be used in vehicles? The answer is no. Although the embedded system is used like the ordinary DVR, the vehicle-mounted DVR technology is more complicated than the ordinary DVR, and the key to solving the needs is also different. Because the vehicle is in the process of moving, it will inevitably be subject to vibration, dust, large power supply, etc., all of which are destined for the application environment of the vehicle-mounted DVR to be worse than the ordinary DVR.
