Backup camera buying guide

With a backup camera system in your car, you'll gain a well-lit, wide-angle view of what’s behind you – a view that a rear-view mirror just can't deliver. Whether you're safety-conscious, want to keep an eye on something you're towing, or just have a bad habit of crunching bumpers, installing a rear-view video system in your car, truck, or RV is a no-brainer. The big question becomes: what's the best system for you?

We'll discuss the process in three steps:

1. Assess your dash for viewing backup camera video
2. Choose the best backup camera for you
3. Installing your backup camera

Step 1: Assess your dash — how will you view your backup camera?

A backup camera won't do you much good without a screen to plug it into, and what you'll need in a rear-view system will depend on what's already in your dash. If you have an aftermarket touchscreen receiver with a rear-view video input, you're in great shape to shop for rear-view cameras. If not, you'll need to figure out which of the following three categories you fall into.

1) Happy with your factory touchscreen receiver? Find a vehicle-specific solution.

Toyota! Jeep! Dodge! Volkswagen, and more! Enter your vehicle information and explore these vehicle-specific backup cameras with harnesses that match select factory-installed entertainment systems. These backup cameras are often specifically designed to blend in with the exterior of your vehicle.

2) In the market for a new touchscreen receiver? Add a backup cam.

There's no better time to install a rear-view camera than when you're already installing a new stereo in your dash. We carry a wide variety of DVD and GPS receivers that are equipped with touchscreen monitors and rear-view video inputs. When you shift your vehicle into reverse, you'll see a helpful view on your new stereo's display.

Some cameras offer multiple angles when paired with compatible receivers.

3) No room in your dash for a touchscreen? You still have options.

If your dash doesn't accommodate a radio with a video screen or if you don't like the idea of altering your factory dash, you still have options:

Step 2: Choose the best backup camera for you

You can count on backup cameras to be tiny and weatherproof across the board, but there are some variables to consider:

Image sensor

Most backup cameras use either CCD or CMOS sensors. The sensors convert light to signal in two different ways: CCD is essentially analog, and CMOS is digital. Generally speaking, a CMOS sensor draws less power and is more sensitive to image noise than a CCD sensor, but a CCD sensor is slightly better adapted to handle fluctuating lighting scenarios than a CMOS sensor. Depending on the types of environments where you typically drive, the difference may be incidental. In the good ol' tradition of iPhone® vs. Android™, the argument as to which sensor is "better" is ever-evolving and has devotees on either side. In most cases, it won't likely be a deciding factor in which camera you choose.

Parking lines

Many backup cameras provide onscreen guidelines to help you when backing out of precarious positions or when squeezing into a tight spot. They help you gauge distance from objects in your path. If you want the flexibility of opting in or out of parking lines, look for "selectable parking lines" as a feature. Some give you the opportunity to remove them during installation, so that you can use the selectable parking lines feature built into certain touchscreen receivers. If you like the idea of parking lines that bend as you turn your steering wheel, predicting your trajectory in reverse, look for "active parking lines" as a feature. 

Mirror image

This is just what it sounds like. The view in your monitor is reversed to mimic that of a rear-view mirror. With some cameras, this is a selectable feature, which is handy if you plan to use the camera as a front-view camera.

Viewing angle

Generally, backup cameras provide a healthy horizontal viewing angle, with some as expansive as 190-degrees. Naturally, the wider you go, the more you'll see behind you at a glance.

Low light

On some cameras, you may see a minimum Lux rating. This tells you the least amount of light required for an acceptable picture. For your reference, a night with a full moon is rated at around 0.1 Lux while a sunny day rates at around 10,000 Lux. Many cameras enhance their low light capability with an additional LED or infrared light that powers on when your vehicle is in reverse.

Mounting

This is the defining feature for most rear-view cameras. It can be done is several ways, so take at look at the rear of your vehicle before you select a camera. Here are the mounting styles to consider:

Step 3: Installation – adding the backup camera to your vehicle

DIYers should anticipate a 3-part installation:

1. Installing the camera in the rear of the car and wiring it for power.
2. Running a video connection from the camera to your dash, unless it's a wireless system.
3. Connecting that video cable to the input on the rear of a compatible monitor (which will also require installation) or your stereo (which involves removing the stereo from your dash and then reinstalling it).

A wireless backup camera system will cut down on your installation time, but you'll still have to wire the camera and monitor for power. In many cases, tapping into the feed to your tail lights will suffice for the camera, but some may require a direct connection to your car's fuse panel.

Life in reverse

Like an air bag to a seat belt, a rear-view camera system isn't a replacement for your vehicle's mirrors, it's a complement — a powerful tool for driving safely and parallel parking like a pro. And even if you consider yourself a pro, everybody has their bad days, and a rear-view system cuts down on the risk of a fender-bender (or worse).
