How to Install a Dual-Camera Dash Cam?
3 Answers
The installation steps for a dual-camera dash cam are as follows: 1. Fix the dual-camera dash cam onto the car's rearview mirror. 2. Insert the car charger cable into the USB port of the dash cam to connect it to the device. (Designs may vary slightly between models; refer to the manual for specific instructions.) 3. Tuck the cable into the gap between the roof lining and the glass, route it along the roof and down the car body to reach the car's cigarette lighter socket. 4. Insert the car charger plug into the cigarette lighter socket. 5. Connect the rear camera plug to the AV-IN port. 6. The wiring process is the same as in the first part. 7. Once reaching the rear of the car, attach the rear camera near the rear license plate.
Installing a front and rear dual-camera dash cam isn't actually difficult, you can do it yourself at home. First, locate the center position above the windshield and stick the front camera there, being careful not to obstruct your view. The rear camera should be fixed on the inside of the rear window, usually using 3M adhesive. The trickiest part is routing the wires—I used a plastic pry tool to tuck them along the headliner gap, hiding the cables behind the door seals, and finally connecting them to the cigarette lighter power source. Remember to secure excess wiring with cable ties to avoid tangling with the foot brake. After installation, power it on to test the angles, ensuring the front camera captures the entire front of the car and the rear camera clearly covers vehicles behind. The key to keeping the interior tidy is patiently threading the wires—don't rush and yank them forcefully.
As a car owner who frequently installs in-car devices myself, I believe safety is the core of installation. Before starting, disconnect the negative terminal of the car battery to avoid short circuits. Do not place the front camera behind the rearview mirror area, as this position may interfere with airbag deployment. When routing wires, avoid placing them over seat belts and secure them along the side of seats using plastic clips. The rear camera installation position should avoid heating wires, otherwise the lens may be damaged during defrosting. For power connection, prioritize tapping power from the fuse box for long-term stability, while the cigarette lighter is only suitable for temporary use. After completion, check that all wiring harnesses are securely fastened to avoid potential safety hazards. Finally, test the nighttime recording performance to ensure both front and rear cameras can capture clear footage.
