Q8: Why parking surveillance function doesn’t work?

The working principle of parking surveillance: it is the same as recording video in emergency situations. It uses a gravity sensor (G-sensor) to sense, wake up the driving recorder and record video.

Under normal circumstances, it is difficult for a person to push the door forcibly to simulate a large impact or acceleration similar to an accident. Therefore, it is normal that it doesn’t record an emergency video when shaking the door forcibly.
