Rear-View Vehicle Cameras: A Watchful Eye On The Road

Backup cameras, also known as reversing or rear-view cameras, are now standard in new cars. They are designed to aid reversing and reduce the rear blind spot, which has been described as a killing zone due to the number of accidents it contributes to.

Backup cameras are typically mounted on the rear of a vehicle, pointed backward, and connected to the head unit display or rearview mirror. They can be wired or wireless, and some simulate a bird's-eye view of the vehicle and its surroundings.

Aftermarket options are available for older vehicles, and there are also cameras designed specifically for large vehicles such as RVs and trailers.

Backup cameras are now standard in new vehicles

Backup cameras, also known as reversing or rear-view cameras, are now standard in all new vehicles sold in the US and Canada. This is because, in 2018, the US Department of Transportation mandated that every car coming off a production line must feature a backup camera. This was also regulated by law in Canada in the same year.

Backup cameras are video cameras attached to the rear of a vehicle, designed to aid in reversing and reduce the rear blind spot. This blind spot has been described as a "killing zone" due to the number of accidents it has contributed to.

The history of backup cameras

The first backup camera was used in the 1956 Buick Centurion concept car, which was presented in January 1956 at the General Motors Motorama. The vehicle had a rear-mounted television camera that sent images to a TV screen on the dashboard in place of the rear-view mirror.

In 1972, the Volvo Experimental Safety Car (VESC) also had a backup camera, but this feature did not make it into the subsequent Volvo 240 model.

The first production car to incorporate a backup camera was the 1991 Toyota Soarer Limited (UZZ31 and UZZ32), which was only available in Japan. However, this system was discontinued in 1997.

Backup cameras are typically connected to the vehicle's head unit display and are wired to automatically activate when the transmission is set to reverse. They usually have a wide-angle or fish-eye lens, which allows the camera to see an uninterrupted horizontal path from one rear corner to the other. The camera is also typically pointed at a downward angle to view potential obstacles on the ground.

Different types of backup cameras

There are several different types of backup cameras available on the market, including:

• Aftermarket additions: These can be added to vehicles that do not have factory-fitted systems and are available in wired and wireless versions.
• Large vehicle systems: For large vehicles such as motorhomes, camera systems with built-in servomechanisms allow the driver to remotely pan and tilt the camera.
• Wireless backup cameras: These come with a wireless camera and receiver, making them easier and cheaper to install.
• Built-in audio intercoms: Used in addition to the camera system for communicating with a spotter outside the vehicle when backing large trailers or launching boats.
• Night vision cameras: These use a series of infrared lights for backing up in the dark when the vehicle's white reverse lights are insufficient.
• Portable or semi-permanent all-in-one camera systems: Also known as dashboard or dash cameras, these are typically sold for vehicles that don't have displays permanently installed in the dashboard.
• License-plate-frame versions: These permit installation without any permanent vehicle modifications.
• Custom cameras: Brake light cameras combine a camera with brake light functionality. Some backup cameras also use LEDs surrounding the camera lens to illuminate the surroundings while in use.

Aftermarket options are available for older vehicles

Aftermarket backup cameras can be added to vehicles that do not come with factory-fitted systems. They are available in both wired and wireless versions. Wired cameras are hooked to output screens with wires, which means the connection is stronger, but professional installation may be required.

Camera features: night vision, wide-angle lens, etc

When it comes to vehicle cameras, there are a variety of features that can enhance your driving experience and improve safety. Here are some key camera features to consider:

Night Vision

Night vision is an essential feature for driving in low-light conditions or complete darkness. It allows the camera to capture clear footage, helping you navigate and avoid obstacles when backing up at night or in dimly lit areas. This feature is particularly useful for those who frequently drive in areas with limited lighting, such as rural roads or unlit parking lots.

Wide-Angle Lens

A wide-angle lens provides a broader field of view, reducing blind spots and enhancing your peripheral vision. This feature is especially valuable when manoeuvring in tight spaces or reversing, as it allows you to see more of the area surrounding your vehicle. Wide-angle lenses typically offer a viewing angle of around 110 to 180 degrees, giving you a more comprehensive view of your surroundings.

High-Definition Resolution

High-definition (HD) resolution, such as 1080p or higher, ensures that the camera captures clear and detailed footage. This is crucial for identifying potential hazards, reading license plates, and getting a precise view of your surroundings. HD resolution also improves the overall driving experience, providing a sharper and more defined image on your display.

Waterproof Design

A waterproof or water-resistant camera is designed to withstand the elements, protecting it from rain, snow, and other environmental factors. This feature ensures that your camera remains functional and reliable even in harsh weather conditions, providing you with uninterrupted visibility and peace of mind during your drives.

Motion Detection

Motion detection is a valuable feature that automatically detects moving objects within the camera's field of view. This can be particularly useful for security purposes, as it can alert you to potential hazards or unwanted intruders near your vehicle. Additionally, motion detection can be used to optimise recording, triggering the camera to start recording only when motion is detected, conserving storage space and battery life.

Parking Guidelines

Parking guidelines or distance scale lines are superimposed on the camera's display, providing you with a visual reference for distance and manoeuvring. These guidelines assist you in judging distances accurately when reversing or parking, making it easier to avoid collisions with obstacles or other vehicles.

Wireless Connectivity

Wireless connectivity eliminates the need for cumbersome cables and makes installation simpler and more straightforward. Wireless cameras often utilise digital signals to transmit footage to the display, resulting in a stable and interference-free image. This feature enhances convenience and flexibility, allowing for easier installation and a neater overall setup.

By incorporating these features into your vehicle camera, you can enhance your driving experience, improve safety, and gain greater peace of mind while on the road.
