About The Reversing Assist Function:

If the kit you ordered includes a rearview camera and you need to implement the reversing assist function, you need to connect the red signal wire of the rearview camera to the car's reversing light (the light will come on when reversing). If you don't need the reverse assist function, just disconnect the red signal wire and leave it unconnected.

About 24-Hour Parking Monitoring:
If you need the 24 hour parking monitoring function, you can order the corresponding Buck Line accessories to replace the car charger.Through Buck Line, the DVR power can be obtained directly from the car battery or car ACC, so that the DVR can maintain normal recording work even when the car is turned off.(Since different car models have different battery interfaces or ACC interfaces, it is not recommended to install it by yourself. It is recommended to find a professional to install the Buck Line.)
