Wireless Rear View Camera: Wireless Rear View Camera System Installation Guide

When it comes to installing a DIY backup camera, the easiest system to install is a wireless backup camera that uses the existing rear license plate mounting holes. It’s much easier than installing a wired backup camera as there is no need to run several feet of video cable from the rear of your car, through the cabin and up to the dashboard. Aside from that, every rear camera installation is basically the same.

Reversing cameras have become an increasingly popular safety feature, coming standard on many new cars. In just a few years, rear view cameras will be mandatory for all new cars.


The tools you need are simple:

  • Either a blade or Phillips screwdriver to remove the license plate and license plate light and mount the camera
  • Double sided tape instead of screws to fix the transmitter or power supply in the back of your vehicle
  • You can use a drill driver to mount the wireless transmitter in the back of your vehicle
  • If you cannot use the license plate light to route wires, you may need to use a drill to drill a small hole to route the wires
  • If you need to drill a hole, make sure you use the rubber grommet that came with the kit to protect the wires from the rough edges of the hole
  • Wire connections for splicing the power wires into the reverse light wiring
  • Make sure you have an available 12V power connection to connect the video display monitor, or have a plan to hardwire the video display to your existing under-dash wiring

Wireless backup camera system installation steps

Every wireless backup camera system comes with three main components; a camera, a transmitter and a video display/receiver.

Mount the camera

  1. Mount the reversing camera to the rear license plate by removing the license plate mounting screws and use them to mount the camera.
  2. Every vehicle requires an illuminated rear license plate and this is usually done with two lights on either side and above the plate. Remove the light closest to the camera mount cable source and thread the wires through the hole with the other light cables. Replace license plate light.
  3. Route the wires in the back of your car or trunk to the nearest rear taillight housing. You need to identify the reverse light wire and connect the appropriate camera power wire to this wire. This ensures that the camera system only works when your vehicle is reversing. This is for security.
  4. The wireless transmitter must also be mounted in the trunk or rear of the car and connected to the camera’s corresponding cable. Once this is complete you are done at the rear of the car.

Mount the video display

  1. The video display is easy to install but can be difficult to achieve a finished look. Most devices simply plug into a 12V outlet (like a cigarette lighter) for power and may even have a built-in receiver.
  2. The video display can often be mounted on the dashboard or windshield using the bracket provided.
  3. Some video displays take the form of a replacement rear view mirror. These are usually mounted over the existing transom with built in adjustable clamps. A rear view camera replacing the existing mirror is more difficult to install and those steps are not covered here.
  4. If you decide to hide the wiring, you can route the power cord into the headliner, down the A-pillar, under the dash and either to the nearest 12V power plug, or wire it directly to the vehicle’s wiring.

Test the system

  1. Turn on the car and put it in reverse. The video display should turn on automatically when the rear camera video is displayed.
  2. If you move the car’s gearbox to a different position, the video display should be blank.

With your new aftermarket backup camera system installed, you can reverse and park safer than before. It’s easy to see why a wireless backup camera is such a popular safety device in vehicles.
