Types of Vehicle Backup Cameras

There are 3 types of backup cameras:

License Mounted Cameras

The camera is fixed in the open license plate hole, thereby making installation easier since there is no modification or drilling new holes. The camera can be positioned close to the road or off-center depending on where your plate is.

Flush Mounted Cameras

The camera is fixed through a hole in the vehicle’s body. You will only be able to see the bezel and the lens which give a good clean look. The camera is at the same level as the road thereby not providing great depth.

Surface Mounted Cameras

The camera can be fixed on any flat surface and is mostly fixed high up. It provides a great view and wonderful depth perception from this position. This is an ideal choice for larger vehicles.

Did You Know How Vehicle Backup Cameras Work?

The moment you set your car to reverse, the camera fixed at the rear of your vehicle powers on and sends an image to the monitor to show you what is at the back of your car. It seems quite simple; however, there are some complications.

Even the most basic camera systems are quite sophisticated and the technology used is always changing. Complications begin with the image which is captured by the camera.

Instead of broadcasting the picture which a normal camera may see, backup cameras are designed to broadcast a mirror image to the screen so that the orientation is right when you see it.

If you look at the direct broadcast of what the camera sees, the image you see would be reversed and you might steer left instead of right. The camera system has a reverse function to correct this so that the view on the monitor makes sense.

ZEROXCLUB Digital Wireless Backup Camera display
Backup display

 Backup cameras are mostly installed in the trim pieces of the vehicle’s rear. They are quite inconspicuous which means you may not see them easily; however, you may find them hidden near the license plate, in the trunk lid or in the bumper.

The backup camera normally aims towards a lower angle in order to give you the best view of what lies behind your car. In addition, it has wide-angle lenses so that it provides you with the same image you would get from a rearview mirror.

The monitor can be fixed anywhere along the field of vision of the driver, however, it is mostly located in the central area of the cockpit. Because many new cars have a monitor for navigation, climate control, and the entertainment system, the same monitor is usually used for the backup camera.

Other camera systems use a part of the rearview mirror as the screen which favors drivers who like looking when reversing. It is important to note that this monitor is very small and gives you a less detailed image compared to the one on a large screen.

While some older experimental camera systems and quite a few aftermarket models use monochrome monitors and cameras, almost all of them have color displays.

Some latest models have high-resolution cameras to provide high definition display which might not be as great as a new flat-screen TV. Currently, vehicles like the Mercedes-Benz S-Class, the Cadillac CT6 and the BMW 7 Series have backup cameras with night vision capability.

Considerations To Look At Before Buying Vehicle Backup Cameras

If you are looking to buy a new backup camera, you should avoid some pitfalls that will lead to serious regret. Therefore, it is important for you to make an informed buying decision. Some cameras also use a digital wireless signal that prevents interference and have reasonable price.

If you are looking to save some money, you should go for the because it also performs great. The most important thing that you need to consider before buying a vehicle backup camera is image quality. Here are the biggest factors you should consider:

If you are looking to save some money, you should go for the because it also performs great. The most important thing that you need to consider before buying a vehicle backup camera is image quality. Here are the biggest factors you should consider:

Field of View

The focal length of the lens, image type, and sensor size determine the field of view of the backup camera. Just like the normal camera, a bigger sensor provides better image quality, performs great in low light and achieves a wider field of view. For example, a 1/3” sensor delivers about a 120deg field of view while a 1/4” sensor delivers about a 90deg field of view.

The least field of view you should accept is 90-deg, however, I recommend you buy anything not less than 120-deg. There are some units on the market with very wide-angles of 180 and 210 which may sound great but provide a fish-eye lens effect that makes it difficult for you to use when reversing. It is like looking through a peephole which is strenuous and can cause an accident.

Types of Monitors

Most modern monitors are liquid crystal display (LCD); however, you may still be able to see a couple of cathode-ray tube (CRT) monitors. CRT is old-fashioned technology which provides poor video quality. Apart from LCD monitors, there are TFT-LCD screens which are considered the best in terms of quality video.

The most popular sizes are 5”, 7” and 10” units and there are also smaller sizes available. Most modern cars have supplementary input and a built-in SatNav unit. If your car has a SatNav unit, you do not need to worry about a monitor since you can fix your camera right into the SatNav unit as long as it is compatible with it.

Image Sensors for rear-view camera

Sensors for rearview cameras are either CMOS or CCD. Greater video quality comes from CCD than CMOS sensors. CCD sensors operate in environments with lower-light environments and are more costly than CMOS sensors. Do not let the money factor stop you from getting the CCD sensors because a CCD camera unit is the one you need to purchase.

Infrared Night Vision for backup camera.

A lot of backup cameras are fitted with infrared night vision. The rearview camera has LED infrared lights that will show you pictures even when it is totally dark. However, you should not expect to see images a long way into the distance.

The normal distance for infrared is 20 to 30 feet and the color will be monochromatic. Do not purchase a camera model without infrared because so many models have it.

Wired vs. Wireless Backup Cameras

Wireless backup cameras face interference problems and as a result, they are unable to provide the same video quality. The interference appears as stripes on your screen which can be irritating.

The wireless unit is based on the premise of reducing wiring between the screen and the camera; however, you still wire a power source to both wireless and wired units.

With this in mind, you will lean more towards the wired unit. If you are in favor of a wireless unit, you should try to reduce the distance between the camera and the monitor.

Mirror Image Capability

The system has to be able to ‘flip’ the image for you to see the image you would have expected to see in your rearview mirror. This enables you to reverse easily because, in your mind, you expect to see it that way.

There are units that allow for reversed or normal image and almost every unit has the reverse image function. Therefore, you should not buy a backup camera that does not have the reverse image function.

Automatic Power-On

The automatic power-on function is on most high-end systems. Connected to the reverse lights of the car, the unit automatically powers on when the car shifts into reverse. It is completely tiring for you to have to switch the unit on whenever you want to use it. Ensure that your unit has this function.

Audio Monitoring

Some backup cameras include a microphone which comes in handy especially when you are reversing a long trailer. If you require a microphone, there are so many options you can choose from.

Power Supply to the back up camera.

Some cars work on a 24V system but most work on a 12V system. Ensure that you find out the type of power the camera system needs. You must have a filter or voltage regulator to ensure longevity. Cheap camera units do not have filters.

Weather Resistant for back up camera.

The lifespan of your camera and connectors will be very short if they are not rated for outdoor conditions like grime, snow, rain, and sun because the wiring and camera will be exposed to these different weather conditions. Normal household RCA connectors will not do the trick so you should not buy a camera unit that has them.

Benefits of Vehicle Backup Cameras

At this point, you probably have a pretty good idea about what the benefits of vehicle backup cameras are. A backup camera is ideal for those who tow a trailer because it provides them with a close-up view of the trailer as it lines up with the vehicle’s hitch. In addition, voice sensors and line colors update you on the distance. Here are the benefits you can look forward to once you buy your backup camera:

Back up camera help Protects People

The most important benefit of a backup camera is that it provides injury based or fatal reverse accidents by increasing your field of vision below the rear trunk or window level. They also enable you to see beyond the width of a mirror’s image by removing blind spots.

A kid playing behind a parked vehicle at a parking lot.

You also get warnings in terms of modern color displays that change from green to yellow when you approach any obstruction. This color warning together with a voice warning from rearview sensors are very significant in preventing reversing accidents.

Back up camera help You Park More Safely and Quickly

Backup cameras provide you with a much more accurate and clear view of any obstacles that are behind your car. In addition, most rearview camera systems have a warning tone that alerts you when you are headed too close to an object.

Almost every backup camera has guidelines on the screen which have two parallel lines that guide you on how to get into and out of parking areas easily.


It is very important for you to buy the right backup camera so that you can experience the best quality available on the aftermarket. Follow the above guidelines to identify the appropriate best wireless backup camera system to install in your vehicle. By doing that, I trust that you will have an easy time reversing your car and you will protect lives in the process. Wish you the best!
