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.

    My 70mai Dash Cam Pro Plus+ (A500S) does not have time-lapse video recording, even when connected with the hardwire kit. Why does it not have the time-lapse function? Will you update it to include time-lapse recording with the next firmware update?

    Please note that your FAQ's are incorrect - there is no Time-lapse directory in the Album.
