Parking monitor provides surveillance on your parked vehicle. When the engine is off,
the hardwire kit is used to provide continuous power and protect your car battery
from being discharged.
To enable the Parking Monitor, you'll need to connect it with the Smart Hardwire
Kit (ASIN B07RN24B7V, sold separately).
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.
Please go to https://www.rexingusa.com/support/videos/ to watch a video tutorial
about the installation.

Note:
If you do not use the parking mode function, please change the Gravity Sensing

Key Sound
Allows you to turn the device's button sound effect on or off.
There are 2 options under parking mode:
We recommend using the Time Lapse option.
• Time Lapse Record:
Record video in one frame per second to conserve memory and reduce the time
it takes to review video.
• 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.
To use this feature, you need to connect it with an Intelligent Hardwire Kit (ASIN
B0973MBCT8, sold separately). Make sure that the Parking Mode is turned off on
your dash cam.
Once the sensor has detected MOTIONS. The intelligent hardwire kit will powerup
the dash cam automatically and start recording until the MOTION is cleared.
Option 2: Motion Detection

The GPS logger is integrated on the power cable, which allows you to view your
speed and location when you playback your recordings using the GPS video player.
After a GPS signal is found, the screen icon will turn from blue to green.
