Installing a dual dash cam sounds harder than it is. The idea of pulling trim apart and threading cables through your car makes it feel like a job for someone more technical. That’s usually why dash cams sit in boxes for weeks after purchase. I finally installed mine after realising something simple: you don’t need skill. When you break the process into calm, logical steps, it becomes very manageable.
This guide walks through how to install a dual dash cam, focusing on clean cable routing, correct camera angles, and memory card setup.
Before You Start: What You Actually Need
You don’t need a toolbox that looks like a mechanic’s drawer. Here’s what helped:
- The dash cam kit (front unit, rear unit, cables)
- MicroSD memory card
- Cleaning cloth or alcohol wipe
- Trim tool or something flat and plastic
Make sure the car is parked somewhere bright and quiet. This isn’t something you want to rush in a dark garage.
Step 1: Choose the Front Camera Position
Start with the front camera. The best spot is usually behind the rear-view mirror, high on the windscreen. This keeps it out of your direct line of sight while still giving a clear view of the road. Before sticking anything down, sit in the driver’s seat to check visibility and make sure it doesn’t block your view.
Clean the glass properly. Dust or residue can cause vibration later, which affects footage quality. Once it’s mounted, don’t worry about perfect angles yet; you’ll fine-tune those later.
Step 2: Mount the Rear Camera Thoughtfully
The rear camera placement matters more than people think. Mount it high on the rear windscreen, centred if possible. Avoid placing it where rear wipers or heavy tinting distort the view. Check that it has a clear view out the back and that defogger lines don’t block the lens too much. Again, clean the glass before mounting for a stable, clean image.
Step 3: Plan Cable Routing Before Hiding Anything
This step saves the most frustration. Before tucking cables away, loosely run them to see where they’ll go. Most people route the front camera cable along the headliner, down the A-pillar, around the door trim, and through the roof lining to the rear. Use a trim tool or your fingers to gently push the cable into gaps. Avoid airbags: cables should never cross airbag deployment areas.
Step 4: Run the Rear Camera Cable Cleanly
Rear camera cables are longer and easier to tangle. Work slowly from front to back. Tuck the cable along existing trim lines so it stays invisible. If your car has rubber door seals, gently pull them back and tuck the cable underneath. They pop back into place easily. This is the difference between a neat install and one that annoys you every time you get in the car.
Step 5: Connect Power Without Clutter
Most dash cams draw power from the cigarette lighter or USB port. Plug the power cable in and route it so it doesn’t dangle or cross pedals. Loose cables near footwells are distracting and unsafe. Once powered, start the car briefly to confirm the camera turns on automatically and both units are detected.
Step 6: Adjust Camera Angles Properly
This step is often rushed, but it shouldn’t be. For the front camera, the horizon should sit near the middle of the frame, and the bonnet edge should barely be visible. For the rear camera, centre the view and ensure approaching traffic is clearly visible. Take a short test drive and review the footage to make any final adjustments.
Step 7: Insert and Format the Memory Card
Insert the microSD card into the dash cam and format it using the camera’s menu. Formatting ensures compatibility and reduces file errors. Use a high-quality memory card and avoid very old cards. Reformat occasionally to keep things running smoothly. Once formatted, the dash cam will record in loops, overwriting old footage automatically.
Step 8: Final Tidy-Up and Checks
Now go back and press all trim pieces firmly into place. Check that no cables are visible, nothing rattles when you drive, and the cameras power on reliably with the car. One more check of the footage quality in both directions will save you future annoyance.
Common Mistakes to Avoid
- Don’t route cables across airbags
- Don’t mount cameras too low on the glass
- Don’t skip cleaning the glass before sticking the mounts
Living with a Dual Dash Cam After Installation
Once installed, you stop thinking about it. The system turns on automatically, records quietly, and manages storage on its own. You only interact with it if something unusual happens. That “set and forget” aspect is what makes a dual dash cam worthwhile.
Final Thoughts
Installing a dual dash cam requires patience, but it doesn't require expertise. If you take your time, the result feels professional. Using a setup like the Kleva Front & Rear Dash Cam makes the process smoother because everything is designed to work together. Once it’s in, it works quietly in the background, ready when you need it and invisible when you don’t.
