Comment Installer une Dashcam Moto et Voiture (Guide 2026)

Installing a dashcam is a smart investment in your vehicle's security. In this guide, we'll explain two methods: using a cigarette lighter adapter (CLA) or a direct wiring approach. We'll also address common questions to ensure a smooth installation process.

How to Install a Dash Cam?

Using the cigarette lighter adapter (CLA)

This installation method is simple and convenient, requiring no modifications to the vehicle's electrical system, but it may result in an unstable power supply for the dashcam. The installation steps are as follows:

1. Choose the installation location for the dashcam, generally recommended behind the rearview mirror, in the center of the windshield, for an optimal viewing angle.

2. Clean the installation location on the windshield, attach the mounting bracket and place the dashcam on the bracket.

3. Connect the cables to the dashcam.

4. Guide the power cable by sliding it behind the headliner and rubber seal along the A-pillar, downwards, passing under the dashboard.

5. Plug the power cord into the cigarette lighter socket.

6. Insert the memory card into the dashcam, start the car and the camera will begin recording.

Direct wiring method

This installation method can provide a more stable power supply and does not occupy the cigarette lighter socket, but it requires more installation steps and modifications to the vehicle's electrical system, which may require professional skills or qualified personnel. The steps are as follows:

1. Required Tools

Direct wiring kit
Test screwdriver
Long pliers
Key
Trim removal tool

2. Locate the mounting points

Choose the camera location: usually behind the rearview mirror, in the center of the windshield.

3. Install the dashcam mount

Clean the chosen location, stick the bracket on and install the dashcam on it.

4. Locate the fuse box

Locate the fuse box and ground point, often under the dashboard on the driver's or passenger's side.

5. How to install the dashcam cable

Connect the cables to the dashcam and route the power cable. Run it along the headliner, from the A-pillar rubber strip, to the fuse box, avoiding the airbag wiring.

⭐Note: In the direct wiring kit, the yellow wire is for the battery, which must be connected to a constant fuse location. The red wire is for the ACC, which must be connected to an ACC location, and the black wire is for ground, which must be connected to a ground point.

6. Connect to the ground point

Loosen the ground point screw, connect the black ground wire from the direct wiring kit and tighten the screw.

7. Find a permanent fuse location

Turn off the ignition, use the tester to detect a location that remains live.

8. Install the fuse

Use long pliers to remove the fuse, install it in the yellow battery wire of the direct wiring kit.

9. Insert the yellow battery wire into the original fuse slot.

10. Connect the ACC port

Use the tester to locate a location that is only powered when the ignition is on. Remove the fuse, install it in the red ACC wire of the direct wiring kit, and insert the wire into the original fuse location.

⭐Note: The camera now has a constant power supply and the built-in voltage cutoff function will protect your battery.

11. Use cable ties to secure excess power cable.

12. Test the dashcam

Insert the memory card into the dashcam, turn it on and configure it.
