How to Install a Rear Camera for a Dash Cam?
4 Answers
The installation method for a rear camera of a dash cam: 1. Mount the rear camera above the center of the rear windshield; 2. Route the wiring through the trunk, along the edge of the trunk, and then install it on the license plate light cover, adjusting the angle as needed. Installing the rear camera for a dash cam requires concealing the wiring, which can be quite complex if done by oneself. Poorly routed wires may affect aesthetics, so it is recommended to seek professional installation for peace of mind. A dash cam is a device that records images, sounds, and other relevant information during vehicle operation. After installing a dash cam, it can record the entire driving process in video and audio, providing evidence in the event of a traffic accident.
Installing a rearview dash cam isn't actually that difficult - I managed to do it myself. Start by routing the cable from the roof, using a soft plastic pry tool to tuck the wire into the interior panel gaps, then conceal it along the A-pillar and B-pillar all the way to the trunk. The key is to avoid the airbag locations. Next, remove the trunk trim panel to locate the reverse light wiring for connection. I prefer using a circuit tester to confirm positive/negative poles - connect the red wire to the reverse light's positive pole and ground the black wire. Mount the camera directly above the rear windshield; clean the glass with alcohol before securing with 3M adhesive to ensure strong adhesion. Finally, plug in the power to test the image, adjusting the angle to clearly display license plates and vehicles behind. The entire process took just over an hour - simpler than expected.
The most troublesome part of rear camera installation is routing the wiring. I recommend planning the route carefully before starting. It's best to run the wires along the roof edge and door seal rubber trim for maximum concealment. Remember to avoid the airbag area near the A-pillar, and use cable ties to secure the wiring harness to prevent rattling noises. The wiring connection is most critical: locate the reverse light wiring harness, usually found behind the left trunk interior panel. After connecting the power with wire strippers, wrap the connection tightly with insulating tape to prevent short circuits. For mounting position, choose a spot slightly above center on the rear windshield to avoid wiper obstruction. Finally, during power testing, engage reverse gear to confirm automatic screen switching, and check infrared night vision performance. For DIY installation, just prepare plastic pry tools, insulating tape, and a circuit tester - this saves over 200 yuan compared to shop installation.
Three Key Points for Installing Rear Camera: Wiring, Connection, and Debugging. When wiring, tuck the cable from the recorder host along the roof gap to the trunk, ensuring no pressure on the cable throughout the process. Connection must be done with the power off—strip the reverse light wire and connect (red wire to positive/black wire to ground). Attach the camera to the center of the rear window glass inside using 3M adhesive, and remember to remove the lens protective film. Finally, power on for testing to ensure a clear rear view when reversing. Focus on checking night imaging and adjust the angle slightly if necessary.
