Rear camera installation
15
Rear camera installation
We recommend install the rear camera above the license plate.
1. Fix camera with 3M adhesive
Find a best location tear off the 3M adhesive on the rear camera, fix
the rear camera near by the car license plate lamp. (if you need to
adjust the angle, please attach the rear camera bracket to the rear
camera and tighten it with screws first).
2. Remove the Panel
Remove the inner panel of the trunk to expose the rear wiring
compartment of the car. Open the trunk and look for a sturdy inner
panel covering the other side of the license plate installation area.
Then, insert a decorative removal tool or another thin device behind
the panel and pry it apart.
16
3. Install the cable
Look for lights near the license plate that have gaps to allow wires to
pass through. Run the rear camera cable through the gap into the
trunk of your car.
4. Connect the rear cameras power cable to the extension cable.
After snaking your rear camera's extension cable, connect the power
cable to your rear camera's extension cord.
*If your car has its own reversing assist
system, please ignore the red wire on
the rear camera cable.
17
5. Route your rear camera's power cable to the front of the car.
If you'd like, use a trim removal tool to pop out the headlining panel
directly above your windshield. Then, run your cable through the
exposed chamber.
6. Power on the dash cam with box included car charger, don't
charge it with your own chargers.
NOTE:
We do not recommend to install the rear camera inside the car, it will make the effect of the rear
camera worse. If you need to install the rear camera in the car, please purchase a in-car rear
camera (Asin: B09Q84NBFN), or contact us to get it.
If your car is a RV or a pickup truck, you can install the rear camera forward (the bracket is below),
and turn on the "Upside down of rear image" and turn off the "mirror flip of rear image" to adjust
the image.
18
Glare due to high beams is unavoidable. We have an upgraded WDR rear camera (Asin:
B09KRM9QQ5) that can effectively improve this problem.
About the WDR rear camera: it has the function of automatically adjusting the brightness. So it
will look darker than the front camera when shooting during the day. This is normal and not
caused by a camera defect. Also it automatically brightens at night and can reduce the impact of
rear vehicle lights. As shown below:
Day time (The rear camera is a little darker than the front camera).
Night vision (The rear camera is brighter and clearer than the
front camera).
19
If you need a license plate bracket, we also provide this accessory (Asin: B09J7VXQ2T), you can
search by yourself or CONTACT US.
How to install the mirror dash cam

Hardwire Kit Installation
Dedicated Hardware Kit ASIN: B09X1L1GMX or B0BBLCCQ2B
Muti-size Hardware Kit ASIN: B09X9F8GMT
1. Stop the engine.
2. Open the fuse box.
3. Use a power detector to detect the constant power and ACC power (emergency power). *note:
Use an ACC power supply of 15A to 25A. Use a constant power supply below 30A.
4. Connect the yellow fuse to the constant power source, the red fuse to the ACC power source,
and the ground terminal (black wire) to the metal part of the body.
Installation - Connect the following three cables to the car fuse box. (The position of the fuse box
differs depending on the model).
Step:
25
Yellow cable (BATT/B+)
The yellow cable should be connected to the fuse of the constant power
supply in the car fuse box. If you are looking for a constant power supply
in the fuse box: Use a voltage tester to check the fuse to ensure it still have
electricity even if the car engine is off.
Red cable (ACC)
Connect the red cable supply power only when the car engine starts.
Testing method: The tester bulb will light when the engine is on and won't
light when the engine is off.
Black cable (GND)

have screws or metal parts next to the fuse box. Connect the black cable to
the screw or metal part. (As in the picture below).
26

Q: Why is every video recording so short?
Movie Clip Time: 1minutes/2minutes/3minutes
A: We set the recording interval of each video to 1min/2min/3min. This is for the convenience
of finding the locked video later. The main function of the recorder is to record, especially to
record emergency video. If each video is too long and the G-Sensor triggers emergency
recording when a collision occurs, the video will be locked and cannot be covered by the loop
recording, and customers will be difficult to find the video in the subsequent search. You need
slide the longer progress bar to find this locked video. And the capacity of the Micro SD card is
limited, if the locked video is too long, the normal video capacity that can be stored will
decrease.
(Avaliable after correctly installing the hardwire kit)

There are 12H and 24H parking modes, you can choose according to your needs.
NOTE:
Principle
In the time-lapse recording mode, the car will not trigger the G-Sensor when it is vibrated,
and the emergency recording video will not appear in the locked folder.
When the hardwire kit is correctly connected and the Parking mode lapse Recording mode is
turned on, the acc is out of power when the car is turned off (bat is always charged), and the
dash cam detects that the acc is out of power and will stop normal recording and enter the
"Lapse Recording mode".
Advantage
1. Save electricity, will not drain the car battery.
2. Save the SD card space, which is 1/30 of the normal recording.
33
NOTE:
This function needs to connect the hardwire kit(ASIN: B09X1L1GMX), you can buy it yourself
or CONTACT US.
