In this guide, we will show you some useful tips on how to install a wireless backup camera on your car. Before following any of those steps, however, you need to consult the manual‘s guide of the device that you buy. Also remember to turn off the car, disconnect the batteries to make sure that you will not drill in any wires.

In general, the best backup camera is often located on the outside of the car. It is held in a fixed place by the screws on the top of the license plate. You will need to make a small hole in the trunk, behind the license by using a drill. After that, run the video cable from the backup camera to the car’s transmitter, which is often located in the trunk.

To provide the transmitter with energy, you will need to make use of the reverse light power cable of your car by stripping and attaching it to the transmitter’s power cable by using an electrician’s tape. By doing this, the camera and monitor would power on whenever you reverse your car.

This process of installing often takes about one hour. However, it’s worth bearing in your mind that a few backup cameras need even less amount of time. If you are not sure of the safety during installation, remember to consult with an experienced mechanic.

Field of view – bigger means better

When you are reversing your car, it is always better to have the biggest field of view, which would vary in their horizontal angle from 90 to 180 degrees.

In general, it is often recommended to choose a backup camera with 100 degrees or more in its field of view. This is to ensure that you are getting a full coverage of the back bumper. If you are driving a SUV or large truck, you might even need more coverage.

Night vision – a must-have feature

Many people do much of their driving when the roads are dark outside. Therefore, the best backup camera needs to have infrared LED that would illuminate behind the vehicle so that you could see a monochromatic image on the screen. These days, most of camera models available in the market are designed with night visibility feature, even a couple of the more affordable devices around 70 USD.

Wireless signal quality and strength

Interference could be a problem for several models of wireless backup camera. These devices often broadcast on the frequency of 2.4 GHz, which is often used by a wide range of common electronics, including Wi-Fi network and Bluetooth devices. When the interference happens in the signal, it would result in the degradation of the picture quality, even to the degree where it could not be usable at times.

A couple of the best backup cameras are made with the digital signal, which is specific to the receiver as well as the transmitter to avoid interference. This makes sure that you would get the best possible quality of the picture. However, it is rather expensive. The most reasonable device with the digital signal is up to about 120 USD.

In addition, another effective way that some camera manufacturers apply to deal with interference problems is the brute strength. Generally speaking, a strong analog signal would resist to interference better than a weak one. So, if you choose an analog device, remember to look for a larger wireless range than needed. Bear in your mind that the more powerful the signal, the less possible interference would happen.
