8. FAQ
Q1 Camera turns on/off automatically?
To ensure that the output current can reach 5V/1.5A, use our car charger. And ensure that the In- car camera and rear camera are connected correctly.To improve stability, the dash cam may automatically restart once after detecting that a different camera is connected. In addition: the dash cam will automatically start recording when it detects that the power is connected, and it will automatically shut down when it detects that the power is disconnected.

Q 2 Video image blurry?
Remove the protective lens cap and clean the lens, making sure the windshield is clean and free of grease, dirt and debris.
Q 3 Camera getting hot?
It’s normal for your camera to run a little warm. Since video is being recorded at high speed, the dash cam may become very hot during use (not to exceed 158° F/70 °C).
Q 4 My dash cam has no power but will it work on my computer?
Cigarette lighter power cord not working. Check the fuse in the car’ s power cord plug. If you fi nd a blown fuse, check the power cord for damage that might cause the fuse to blow.

Q5 The sound is out of sync with the video during playback? The codec on your PC may not be compatible or may not be the latest standard.
Q6 My computer can ‘t play video files?

Q7 Video has no sound? Make sure the ” Record Audio” setting is turned on in the settings menu.
Q 8 Photos blurry?
