Every car and truck design includes some blind spots. With most vehicle designs, it’s easy to miss low-lying hazards when backing up. That’s why a rear camera is ranked among the top tech devices for cars.

The camera itself is installed at the rear of the vehicle. The placement depends on the design. There are license plate cameras, tailgate cameras and bumper cameras. Then, the live video feed, which turns on when you are in reverse, can be connecting to a screen in your dashboard with camera connectivity, like an in-dash GPS or stereo receiver, or to your rearview mirror.

In addition to giving you a better view of what is directly behind your car, many back-up camera systems also offer trajectory lines showing roughly where your car will travel if you continue in the direction you are going. In other words, when compared with the basic rearview mirror, a rear camera is big upgrade for your spatial awareness.

Back-up camera installation involves securing the camera itself as well as connecting it with power and a screen for you to see. Unless you are particularly experienced with cars and electronics, it is best to choose professional back-up camera installation to ensure everything works properly. For your convenience, Best Buy’s car electronics installation team can help you get your new back-up camera set up and running in your car, truck or SUV.

If you are investing in safe driving technology more broadly, you might also want to consider devices like hands-free communication devices that keep your attention on the road when you’re behind the wheel.

Additionally, you may appreciate a dash camera, which records what is happening on the road around you. One of the benefits of having a dash cam is having protection against fraudulent claims thanks to evidence of road incidents and accidents.
