How to Install a Dual-Camera Dash Cam?
3 Answers
Installation method for a dual-camera dash cam: 1. First, determine the appropriate installation position for the dash cam; 2. Tuck the power cable of the dash cam into the gap of the car's ceiling; 3. Pull down the door frame seal, then use both hands to pry open the A-pillar trim; 4. Insert the cable into the door frame seal and align the A-pillar clips; 5. Pass the power cable behind the glove box; 6. Tuck the cable into the gap and tighten the screws. The working principle of the dash cam is to digitally record and cyclically update the road conditions in front of the car, inside the car, and around the car. The recorded data includes in-car audio, the car's acceleration, steering, braking, etc., which can be used for investigating traffic accident liability.
I just installed a front and rear dual dash cam. The job isn't hard but requires patience. First, find the right spot: the front camera should be mounted near the rearview mirror, ensuring the view isn't obstructed. Use the included 3M adhesive to secure it—don't cut corners, press it firmly. Next is routing the cables. It's best to use a pry tool to tuck them along the A-pillar and headliner gaps to avoid a messy look. The rear camera needs to be stuck on the rear window, close to the license plate position, to ensure clear footage. Run the connecting cable from the trunk to the front, hiding the wiring along the way to prevent tripping hazards. Finally, connect the power—most use the cigarette lighter plug for quick setup, but if your car has an OBD port, it'll look cleaner. My first attempt was a mess; the cables were too loose and wobbled while driving, so I had to redo it. After installation, test it to confirm both front and rear recordings save properly. It adds a lot to driving safety—just remember to regularly check and clean the lenses. The key takeaway from the whole process is carefully arranging the cables to maintain the car's interior aesthetics.
Installing a front and rear dual-camera dash cam yourself is quite enjoyable, with simple tools like a screwdriver and interior trim pry bar being sufficient. I chose the position for the front camera behind the rearview mirror and secured it firmly with strong double-sided tape. Routing the wires is a technical task: tuck the cables into the gaps along the A-pillar and hide them under the weatherstrip to keep things tidy. The rear camera is fixed next to the license plate light, ensuring the angle covers the view of vehicles behind. The connecting wire runs from the tailgate into the cabin—don’t forget to secure it with cable ties to prevent pulling. For power, I connected it to the cigarette lighter for quick and easy setup, though experts might try direct wiring to the fuse box (voltage testing is required). A successful test run with clear recordings means you’re good to go, and seeing both front and rear road conditions brings peace of mind. Practice makes perfect with such installations—don’t fear mistakes, just adjust promptly. During the process, I also found that choosing a dash cam with a high-definition lens makes the footage steadier, enhancing the reliability of your driving records.
