How to Choose Rear-view Camera and How to Install it ?
Posted On May 30, 2018
A rear-view camera is also called a back-up or reversing camera. This is because it is specifically installed to the rear of the car to help reverse or park or to avoid collision with a person or animal. A display screen is installed in the front, near the dashboard, so that it is easier for the driver to look at. Such a camera sports fish-eye lenses or wide-angled lenses. This helps cover as much ground as possible.
Rear-view cameras are produced in different varieties depending on the type of vehicle. There are cameras which can be installed on the number plate, cameras with a built-in audio invoice to communicate with an outsider to step aside, cameras with built-in servomechanisms so that it is easier for the driver to tilt and move around the camera for a better view, custom cameras like the Hummer H2, etc.
Rear-view cameras are either wired or wireless. The wired camera has to be wired inside the car whereas the wireless camera requires a wireless signal transmitter and receiver. The wired rear-view camera is much preferred.
When choosing a rear-view camera, there are certain aspects that you should keep in mind:
- Camera chips. There are mainly 2 types of chips installed in rear-view cameras, a CCD or CMOS. A CMOS chip is much cheaper and it consumes less power. However, it has a low picture quality and needs extra light sources. A CCD chip is a high-quality chip which is used in cameras used for photography. CCD chip is expensive but performs much better.
- The more the definition, the higher the chance of a good quality image. In rear-view cameras a number of lines is given to give you an idea of the definition for example, 420 lines or 520 lines. The higher the lines, the better.
- Night vision. Such cameras have infra-red lighting installed otherwise it would show nothing but darkness and blurry figures
- Getting a waterproof camera extends its life.
- Shock and dust proof. It is a basic requirement for all rear-view cameras to be shock & dust proof.
Here’s how to install a rear-view camera.
Firstly, remove the cable for the power supply from the battery and put it away from the electrode to prevent it from powering the car.
Secondly, determine the position you want to place your rear-view camera. One example on which position to install your camera is to install it on the license plate light because it is easier. Use the accessories package provided with the camera to do so as it contains all the material to help you install it. The camera’s cable passes through the license plate light holder and connects with the reversing power supply and video cable. It has a hidden appearance.
Thirdly, connect the camera’s wires to the light power cord, connect the camera’s video cable to the video extension and the video extension cable to be connected to the AV port.
Finally, restore the battery power supply and power up your car.
