Option 1: Vibration Detection
To enable the Parking Monitor, you’ll need to connect it with a Rexing Type-C Smart Hardwire Kit (Included).
This feature will allow the dash cam to switch to parking mode automatically if the vehicle’s engine turns off and switch back to the normal recording after the vehicle’s engine turns on.
Gravity Sensing Record:
The Gravity Sensing detects significant or sudden movement (such as an impact or collision), it will trigger an event recording. We suggest setting the “Gravity Sensing” to High sensitivity for Parking Mode Recording.
Note:
If you do not use the parking mode function, please change the Gravity Sensing sensitivity to low. Otherwise, the video will easily be locked and the video cannot be deleted by the loop recording function. This will cause the memory card to be full of locked videos and cause the recorder to fail to work normally.
