Rear Camera Installation: A Step-By-Step Guide For Your Car

Adding a rear-view camera to your vehicle can be a great way to increase safety and prevent collisions when reversing. Also known as a backup camera, this device lets you see what's behind your car without having to turn your head. While some newer car models have these cameras as standard, they can also be installed in older vehicles. In this article, we'll guide you through the process of fitting a rear-view camera in your car, covering everything from purchasing the right equipment to the final installation and testing.

Choosing the right camera for your car

Next, you should consider whether you want a wired or wireless setup. Wireless systems are generally easier to install, but they may still require wiring the camera to the reversing light. Wired setups provide a more reliable image without the risk of interference from other wireless devices.

Another important factor is the mounting point of the camera. Cameras are typically mounted on the license plate or in the rear trim pieces, such as the bumper, trunk lid, or tailgate. Some cameras also offer universal mounts, allowing you to place them anywhere you prefer.

When choosing a backup camera, it's essential to consider the image quality, field of view, and additional features. Look for cameras with wide-angle lenses that provide a comprehensive view behind your car, eliminating blind spots. Some cameras offer on-screen guidelines and warning tones to help with parking and manoeuvring. You may also want to consider cameras with night-vision capability or high-resolution sensors for clearer footage.

Finally, think about the ease of installation. Some cameras can be mounted simply by clipping them onto the license plate, while others may require drilling holes and more complex wiring. If you're not comfortable with the installation process, you can always seek the help of a professional or refer to installation manuals and videos provided by the manufacturer.

Removing the rear license plate

Firstly, examine the bolts holding the license plate to determine which tools you will need to remove them. You may need a wrench or a flathead or Phillips-head screwdriver.

If your license plate is held in place by screws, you can use a screwdriver to turn them counterclockwise and remove them. Place the screws in a safe place while you remove the old license plate.

If your license plate is held in place by bolts, you will need a wrench to loosen them by turning them counterclockwise. You may need an adjustable crescent wrench or a small wrench, depending on the size of the bolts. If the bolts are rusted, you may need to use penetrating oil, white vinegar, or an impact wrench to loosen them.

Once you have removed all the screws or bolts, carefully pull the license plate off and set it aside.

Drilling a hole for the camera cable

Drilling a hole for the rear-view camera cable is a crucial step in ensuring a clean installation. Here's a detailed guide on how to approach this task:

Identify the Cable Route:

Before drilling, determine the path of the camera cable. This typically involves locating the rear wiring chamber or hose by removing the trunk's interior panel or trim. Identify an unobstructed path for the cable to reach the license plate mounting area.

Choose the Right Drill Bit:

Select a high-speed twist drill bit that matches the diameter of the camera cable. For most installations, a drill bit with a diameter between 1/8 inch and 1/4 inch (0.32 cm to 0.64 cm) should be suitable. Ensure the drill bit is appropriate for drilling through the car's metal sheet or body panel.

Drill the Hole:

With the drill bit selected, carefully drill a hole in the license plate mounting area. Ensure the hole is positioned directly behind where the camera's power and video cable will be located. Make sure there are no obstructions, and the hole is large enough for the cable to fit snugly.

Use a Rubber Grommet:

To protect the cable and ensure a watertight seal, use a rubber grommet. Slip the rubber grommet onto the camera cable near the non-splitting end. Choose a grommet that fits just inside the drilled hole. This will keep the cable in place and prevent leaks.

Run the Camera Cable:

Pull the camera cable through the drilled hole into the trunk of the car. Ensure the cable is tight, and the rubber grommet is securely lodged in the hole. This will help to maintain a neat and tidy installation.

Seal and Secure the Hole:

After running the cable, you may want to consider sealing the drilled hole to prevent water ingress and corrosion. Automotive wiring grommets can be used, and it's recommended to spray the area with rust-preventative paint to inhibit rust formation.

By carefully following these steps, you can ensure that the hole drilled for the rear-view camera cable is precise, secure, and protected from the elements. This will contribute to a professional-looking installation and help maintain the integrity of your vehicle.

Connecting the camera to the power source

Connecting the rear camera to a power source is a crucial step in ensuring its proper functioning. Here is a detailed guide on how to connect your rear camera to a power source:

Identify the Power Source:

Firstly, you need to identify a suitable power source for your rear camera. The tail lights or reverse lights of your car are a convenient option as they are already located at the rear and receive an electrical signal when the vehicle is put in reverse. This signal is essential to turn on the rear camera when reversing the car.

Understand the Camera's Electrical Needs:

Before establishing the connection, it is important to understand the electrical requirements of your specific rear camera. Some cameras have a composite video connection, requiring a separate input wire for the video signal. Others may have a multi-pin cable that combines both video and power into a single cord. Ensure you are aware of your camera's specifications to facilitate a smooth installation process.

Establish the Connection:

Now, you can proceed to connect the rear camera to the chosen power source. This typically involves running the camera's power cord into the vehicle by either drilling a hole or utilising an existing opening, such as a cable grommet. Ensure that you make your connections watertight to prevent any corrosion issues in the future.

If you are connecting to the reverse lights, you will need to strip and separate these wires. Use a screwdriver or a similar tool to expose the individual wire strands. Then, fuse the camera wires with the reverse light wires by twisting them together. Ensure that you match the positive and negative wires correctly. Wrap the connected wires with electrical tape for insulation and protection.

Test the Connection:

Before finalising the installation, it is crucial to test the power connection. Check if the camera turns on and functions as intended. Ensure that the camera's signal reaches the monitor or screen without any interference. This step helps to avoid having to redo the installation in case of any issues.

Additional Tips:

• Always refer to your camera manufacturer's instructions before establishing any electrical connections.
• Consider making the power connections inside the cabin to protect them from external elements such as rain, snow, and ice.
• If you are uncomfortable with splicing wires or altering your vehicle's electrical system, consult a professional for installation.
• Ensure a clean and well-lit workspace, and gather all the necessary tools and parts before beginning the installation process.

By following these steps and staying mindful of safety precautions, you can successfully connect your rear camera to a power source, ensuring its proper functionality and longevity.
