Back over accidents are responsible for more than 200 deaths and 12,000 injuries each year. The US Congress passed a law in 2008 that would enact measures to use technology to prevent accidents like these. After years of delays, the US Department of Transportation finally announced that new cars must come with a backup camera.

But what if you own or have recently purchased an older vehicle? Can you add a backup camera to an older car, truck or SUV? You most certainly can! In this article, we’ll explain how several different accident prevention and safety systems can make parking and maneuvering your vehicle safer.

What is a Backup Camera System?

In the simplest of terms, a backup camera system includes a video screen within view of the driver that displays an image of the area behind the vehicle when the transmission is in reverse. The camera on the back of the vehicle will be mounted in a location that lets the driver detect objects or people that are normally blocked by the trunk or hatch. In essence, a backup camera system is like having a spotter behind your vehicle telling you if there is anything in your way.

All backup camera systems that have been integrated into the vehicle properly function without any input from the driver. The wiring in the car provides a signal to the camera system as soon as the transmission selector is put into reverse. There are no switches or buttons to press.

The image displayed on the screen mimics that of your rear-view mirror regarding left-right orientation. When looking at the screen, objects on the right of the screen are the right side of the vehicle and vice versa. As we are used to this perspective, it makes using a rear vision camera system much safer.

Rear Vision Camera System Integration

Most factory-installed cameras are mounted above the license plate on a car or in the handle or tailgate emblem of a truck. Aftermarket camera solutions are available to mimic these installation locations. Many vehicles like the Mercedes Sprinter, Ford F-150 and GMC Silverado and Chevy Sierra have aftermarket solutions that look identical to factory offerings. The cameras are water resistant and carry an IP66 (or higher) dust and water intrusion rating. This IP rating means that the cameras can withstand going through the car wash or exposure to the everyday challenges Mother Nature throws their way. Universal cameras are available in surface and flush mount applications. Your mobile enhancement retailer can help you choose the right style for your application.

Camera Quality

Just as when you go shopping for a video or still camera, lens and image sensor quality play a significant role in determining the quality of the image you will see. Inexpensive cameras from the local auto parts or big box store may not respond quickly to changes in image brightness and often can’t handle high-contrast situations. Higher quality cameras offer more resolution to help you see small or narrow objects behind your vehicle.

Video Image Display Options

There are four popular options available to display the camera image inside your vehicle. As we mentioned, all of these displays operate automatically without the need for any input from the driver.

1. Factory Color Display

If your car or truck came with a color display for the factory radio or infotainment system, there are many companies that offer premium integration modules that allow the image from the backup camera to be displayed on this screen. Using a factory screen is the most integrated of solutions and truly mimics a factory-installed system.

Many interfaces have additional camera inputs for forward-facing and blind spot monitoring camera options. Talk to your retailer to find out what is available for your application.

2. Replacement Rearview Mirror with Integrated Display

If your vehicle doesn’t have a color screen, another popular option to display a camera image is a replacement rearview mirror that features an integrated color display. When the camera is not in use, the mirror looks normal and will show you what is happening behind your vehicle. When you put the transmission in reverse, a compact LCD screen shines through the mirrored surface to display the camera image. While typically small in size (around 4 inches diagonally), they work very well and are quite popular.

3. Aftermarket Multimedia Radio

A popular upgrade for older vehicles is to replace the radio with an aftermarket unit that includes a color display. You can choose from simple AM/FM multimedia receivers costing only a few hundred dollars up to state-of-the-art systems with integrated navigation, Apple CarPlay and Android Auto smartphone integration and even vehicle integration and control options. These systems typically include at least one camera input to show what is behind your vehicle. Some will overlay information from factory-installed parking sensor systems for increased safety.

4. Stand-Alone Monitor

If none of the above options suit your application or you require a larger screen, then consider having a stand-alone monitor installed in your vehicle. Commercial applications such as tow trucks, snow plows, garbage trucks, recycling trucks and delivery vehicles often choose a stand-alone monitor. The image is large, and the unit can be placed in a convenient location.

Additional Safety System Options

As we mentioned, the addition of a forward-facing camera is another popular option for large vehicles like 1-ton trucks where it is difficult to see curbs or even other vehicles over the large hood. In most applications, a button or switch would activate this forward-facing camera for parking purposes. These cameras are also great for making sure these large vehicles are parked as close as possible to the wall in a parking garage to reduce how far they stick out into traffic.

Many luxury vehicles combine a parking sensor system with a backup camera. The advantage of adding parking sensors is that they are an active safety device. You don’t need to remember to pay attention to them – they alert you to the presence of an object. Parking sensor systems can be installed in most cars, trucks and SUVs. Many solutions include options for forward-facing sensors.

Did you ever wish you had eyes in the back of your head? When you are backing into a parking spot, being able to know where the car behind you is would save a lot of time and nervousness. If your car doesn’t have a backup camera or parking sensors, then it’s time to visit your local mobile electronics specialists. They can add these parking safety systems to almost any vehicle on the road.

Backup Camera Options

The classic backup camera system consists of a compact camera, typically about a 1-inch cube. The image produced by a backup camera covers a wide field of vision in both the horizontal and vertical planes. The image is reversed from that of a normal camera. When the camera is installed pointing rearward, this reversed image shows objects on the right side of the vehicle on the right side of the display screen. This orientation mimics what you would see in a rear view mirror.

Most cameras are water-resistant so rain, snow, mud and dust don’t affect their performance. The wiring for these cameras is also water-resistant, usually up to the first connection unless specified otherwise. That connection should be inside the vehicle.

Most good-quality cameras use wide-aperture shutters that allow the camera to capture a lot of light, even when it’s dark out. The reverse lights of your vehicle are often more than adequate to light up everything behind you. Most of these cameras are rated down to 0.5 or 1 Lux of light sensitivity. If you need to see in the dark, then there are cameras with built-in IR light transmitters. These can be used inside closed areas, like an engine compartment of a boat or the container of a delivery van.

Cameras can be installed at the top of or above your license plate. Some custom camera solutions are built into replacement tailgate, hatch handles and third brake light assemblies for many trucks and SUVs.

Several companies manufacture wireless camera systems. If you have a vehicle that is difficult to run wires in, then a wireless camera system may be a viable option. Just be aware that the quality of wireless cameras systems varies a great deal. The last thing you want is for an image to be full of noise, or not present at all due to interference. Wireless systems also have a small amount of delay inherent to their design. This delay can be as little as 100 mSec for some WiF-based camera systems up to almost 300 mSec for others that use more conventional AM and FM transmission techniques. You will need to work with your retailer to choose the right camera system for your vehicle.

Monitor and Display Options

There are many options for where the camera image can be displayed. Almost all aftermarket multimedia source units have dedicated rear view camera inputs and triggers. If your vehicle has a color display from the factory, several companies manufacture interfaces that allow an aftermarket camera image to be displayed on that screen. The third option is a dedicated display screen. This display can be a stand-alone monitor that is installed on the dash or in the center console, or is built into a new rearview mirror. Rearview mirror displays are a nice, clean option because nothing stands out as having been added to the interior.

Some camera systems designed for larger vehicles offer side and front camera locations as well. The monitors included with these systems can typically show all four cameras at once in a variety of on-screen configurations. The most elaborate of these systems will stitch the images from the four cameras together to provide a bird’s-eye view of what is around the vehicle. These 360-degree systems require careful calibration to work properly. Most of these multi-camera systems include reverse and turn signal triggers to automatically change which camera is being displayed.

How a Camera System Works

When you put your transmission in reverse, a wire connected to your reverse lights or a reverse gear signal from your transmission triggers the camera system to turn on. You don’t need to press any buttons or flick any switches – it happens instantly and automatically. The camera should be installed and aligned so you can see the ground as close to the rear of your vehicle as possible.

Parking Sensor Systems

An alternative to a camera system is a parking sensor system. Instead of a camera, these systems use several ultrasonic sensors to detect the presence of objects. These sensors emit a very high-frequency signal, then measure how long it takes for that signal to bounce off an object and return to a receiving sensor built into the same small unit. These sensors are typically installed on the rear bumper of your vehicle. When installed properly, they do a great job of detecting even small objects like the post of a sign. This method of object detection is the same as what bats use for navigation.

How a parking sensor system works varies by brand. Some systems have a small display that shows you which sensor has detected an object and how far you are from that object. Most systems use a small beeper or buzzer to alert you to the presence of an object. The system will emit a beeping sound when it detects an object. The speed of the beeps increases as you get closer to the object. The warning beeps usually switch to a solid tone once you are within 12 inches of an object.

More-elaborate parking systems also include front-mounted sensors to help when driving forward into parking spot or garage.

Passive versus Active Warning Systems

Ultimately, cameras and parking sensor systems do the same job: They let you know when you are getting close to something.

One significant benefit of a parking sensor system over a camera system is that it is completely active. You don’t have to make a conscious decision to look at a screen or display to be warned of an imminent collision – the system beeps and tells you.

This isn’t to say that one system is better than the other – they simply differ in how they work. If you were trying to back a pickup truck up to a trailer, a backup camera system would be a huge benefit, while the parking sensor system just tells you there is something behind you.

The Importance of Parking Safety Systems

Here’s a chilling fact: More than 50 children are hit each week in the U.S. by a vehicle that is backing up. Sadly, roughly two of these children succumb to their injuries each week. We aren’t trying to scare you or make you paranoid – but accidents happen all the time while backing up.

If your vehicle didn’t come with a parking safety system, then drop by your local mobile electronics specialist retailer. They would be happy to inspect your vehicle and design a parking solution that meets your needs.
