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.
