How to install a 7-inch TFT LCD monitor for a rearview camera

To install a 7-inch TFT LCD monitor for a rearview camera, you will need to follow these steps:

Firstly, decide on the type of rearview camera you want. There are generally three types of backup cameras available on the market: surface-mounted, flush-mounted, and license-mounted. Surface-mounted cameras are installed on any flat surface, usually high up for an improved rear view. Flush-mounted cameras are installed through a hole in the body of the vehicle and are level with the road, providing a clean look. License-mounted cameras are fixed to the license plate, making installation easy, but if your plate is off-center, your view will also be off-center.

Next, consider the field of view of the camera. The bigger the sensor of the camera, the better the picture quality, especially in low-light conditions. You should also look for a camera with a wide field of view; 90 degrees is the minimum you should accept.

Now, onto installing your 7-inch TFT LCD monitor. This type of monitor usually comes with a dashboard or surface mount. You can install the monitor by clipping it onto your existing rearview mirror, or you may need to drill holes and feed wires through, depending on the model. The monitor should come with a power cable that you will need to connect to your vehicle's power source. The blue wire should be connected to your reverse light power so that the monitor turns on automatically when you put the car in reverse. You will also need to connect the monitor to your camera using an RCA cable.

Finally, test that the monitor and camera are working correctly. When you put your car in reverse, the monitor should automatically display the feed from the rearview camera. You may also be able to turn on the monitor manually using a remote control or touch buttons.

Some monitors will also have additional features, such as brightness and contrast controls, and the ability to connect to other devices like DVD players.

Connecting the monitor to a power source

To connect your 7-inch TFT LCD monitor to a power source, you will need to identify the power input cable. This is usually a red wire, which is the standard colour for positive voltage. You will also need to identify the ground wire, which is typically black. These wires will need to be connected to a power source, such as the car's fuse box or cigarette lighter.

If you are connecting the monitor to a car's fuse box, you will need to locate the fuse box and identify a fuse that is connected to the car's electrical system. This is usually a fuse that is labelled as being for the radio, interior lights, or another accessory. Once you have identified the correct fuse, you will need to connect the power input cable from the monitor to that fuse. This can be done by splicing into the fuse with a fuse tap or by connecting directly to the fuse box with a fuse add-a-circuit.

If you are connecting the monitor to a cigarette lighter, you will need to purchase an adapter that plugs into the cigarette lighter and provides a power outlet. These adapters are available at most auto parts stores and online retailers. Once you have the adapter, simply plug it into the cigarette lighter and connect the power input cable from the monitor to the adapter.

It is important to note that connecting the monitor directly to the car's electrical system may drain the battery if the car is not driven regularly. To avoid this, you can connect the monitor to a power source that is only active when the car is on, such as the fuse for the accessory or ignition.

Additionally, some monitors may have a blue wire which is used to trigger the monitor to turn on when the car is in reverse. This wire can be connected to the reverse light circuit to automatically turn the monitor on when the car is in reverse.

When connecting the monitor to a power source, it is important to follow all safety precautions, such as disconnecting the car battery before making any connections and ensuring that all connections are secure and insulated to prevent short circuits.

Setting up the monitor's display

Step 1: Positioning the Monitor

The first step is to decide on the placement of your 7-inch TFT LCD monitor. This can vary depending on your vehicle and personal preference. Some common locations include mounting it on the dashboard, attaching it to the windshield, or integrating it with the rearview mirror. Consider factors such as visibility, safety, and ease of installation when making your decision.

Step 2: Power Connection

Once you've determined the monitor's location, it's time to establish a power source. The monitor typically requires a 12V power supply, which can be obtained from the vehicle's electrical system. Identify a suitable power source, such as the fuse box or a cigarette lighter plug, and connect the monitor's power cable accordingly. Ensure that the power cable is securely attached and routed neatly to avoid any potential hazards.

Step 3: Video Input

The next step is to establish the video connection between the monitor and your chosen video source. This could be a rearview camera, a DVD player, or another device. Use the appropriate video cable, typically an RCA cable, to connect the video output of the source device to the video input on the monitor. Ensure that the connections are secure and colour-coded correctly (yellow for video).

Step 4: Display Settings

After establishing the power and video connections, it's time to adjust the display settings for optimal viewing. This may include adjusting the brightness, contrast, colour, and sharpness to your preference. Refer to the monitor's manual for specific instructions on how to access and adjust these settings. Additionally, if your monitor has multiple video inputs, you may need to select the correct input source to display the desired video feed.

Step 5: Test and Fine-Tune

Finally, it's essential to test the monitor's display to ensure everything is functioning correctly. Turn on the power source and the video source, then observe the monitor's display. Check for clarity, colour accuracy, and responsiveness. Make any necessary adjustments to the display settings or cable connections to fine-tune the viewing experience.

Remember to consult the installation manual or seek guidance from a professional if you encounter any challenges during the installation process.

Mounting the camera

To mount the camera for your 7-inch TFT LCD monitor, you can follow these steps:

Firstly, decide on the location for your camera. A common location is on the license plate, as mentioned in several reviews. This location provides a clear view for the camera and is easily accessible for installation. However, you can also choose to mount the camera above the license plate or on the rear of your vehicle, depending on your preference and vehicle design.

Once you've decided on the location, gather the necessary tools and materials. You will need a drill, screws, and any additional mounting hardware that came with your camera. Some cameras may have adhesive strips, while others may require you to purchase mounting brackets separately.

Before drilling, clean the surface and ensure it is free of dirt and debris. This will ensure a strong and secure bond between the camera and the mounting surface. Carefully drill holes at the marked locations, being mindful of any wires or components behind the surface.

Next, attach the camera to the mounting bracket or adhesive strip, following the instructions provided by the manufacturer. Secure the camera in place by tightening the screws. Ensure that the camera is firmly attached and won't move or vibrate during driving.

Finally, connect the camera to the power source and test it to ensure it is functioning properly. You may need to connect it to the reverse light circuit or another power source, depending on your setup. Adjust the camera angle as needed to ensure it captures the desired field of view.

By following these steps, you can securely mount the camera for your 7-inch TFT LCD monitor, ensuring a clear view and easy installation.
