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.
