Backup sensors are popular standard features in new cars, but that doesn’t mean you need to buy a new car to enjoy the benefits and safety of having one. Backup sensors use high frequency sound, well above the threshold of human hearing, to detect obstacles the same way bats use echolocation. Most of these sensors are installed into holes drilled into the bumper of your car, but some are able to be mounted on a license plate frame.
Generally, they are powered off of your reverse lights. Some systems combine the ultrasonic sensors with a backup camera to give you even greater coverage. Features to look for are units that give a visual readout as well as an audible warning, displays that combine intuitive color coded lights with precise numerical information, and number of sensors. The more sensors your system has, the more accurate it will be and the more information it can give you about your surroundings. This is a look at ten of the most popular backup sensors available on Amazon.com.

This system is easier to install than some due to the signal being transmitted wirelessly from the sensors to the indicator on the dashboard, which is powered off of the cigarette lighter. The rear sensors are tied in to the reverse lights on your car and mount on your license plate frame, eliminating the need to make holes in your bumper. Unlike more invasive systems, however, the Peak PK0RE only uses two sensors. The dash unit gives a visual indication of distance to obstacles with color coded lights.
This two sensor system mounts behind your rear license plate and receives power from your reverse lights. It can be installed by yourself and gives three levels of audible warnings as you approach obstacles. The product replaces your rear license plate frame for a smooth, discreet look and doesn’t require you to drill into your bumper.
The LESHP Parking Sensor uses eight ultrasonic sensors to accurately gauge both distance to obstacles and their location relative to your vehicle. The unit, powered by 2 high sensitivity CPUs will alarm when danger is detected. The closer the obstacle or object, the louder and faster the alarm will sound. The LESHP Parking Sensor has remarkable 5 out of 5 stars rating on Amazon reviews at the time of writing, with most reviewers commenting on the value for money, ease of fitting the unit and the effectiveness of the sensors.
The Auto Safety Reverse Backup Radar System features four backup sensors which come with everything you need to install the unit. You can expand the system with a further four sensors on the front to provide complete collision cover. The alert sound is a loud, clear human voice rather than a tone warning and the LED digital dash display provides clear distance information as you reverse.
This hardwired system provides a rear view camera with feed to a 4.3″ display monitor for the driver to carefully maneuver in reverse. The display unit is in color and you have the option to view guidelines for safe movement on the screen, or to hide the guidelines. Like most others of its type, the Esky rear view system ships with the required equipment you need for installation.
This is a high quality four sensor wireless backup system. The four sensors and wireless transmitter are powered off of your reverse light, and the dash unit gives both an audio and visual warning as you approach obstacles. This system is 100% weatherproof and the sensors are paintable to match the color of your bumper.
This is a wired, four sensor system featuring a double CPU and advanced chipset to enhance both coverage and detection. The bright display shows both numerical and color coded proximity data, as well as an audible warning. The dash unit attaches via included double sided tape. The system is powered off of your reverse taillight and requires drilling with the hole saw that ships with the kit.
This feature packed sensor package combines four ultrasonic sensors with full color, high resolution night vision camera. The camera mounts easily to the back of your car and the sensors are mounted in the bumper via drilled holes. The package comes with a high quality rear view mirror that contains the video display. The mirror is thin and designed to clip on to your existing rear view mirror for ease of installation and a clean, clutter free look. The Car Rover system is water proof, shock proof, and is resistant to electronic jamming, so you know it will always work. The camera and sensor combination makes parking and obstacle avoidance easy and intuitive.
What sets this system apart from the other wired systems is its larger, more informative display. Instead of simple, color coded lights, the four bumper mounted sensors each get their own region on the lLED dash unit, making obstacle avoidance easy. In addition to the large, premium LED display, the ePath gives a three-zone audible warning.
Most sensors only come on when you reverse. This Napoer system includes eight ultrasonic sensors that remain active while you drive, providing you with information all around your vehicle and alerting you to vehicles in your blind spots. Though installation is more advanced than other models, that minor inconvenience is more than made up for by the enhanced functionality. The color display is large and legible, and the system gives you the option of two actual human voices that give you alerts and guidance. This system packs serious functionality into a low price.
For ease of installation, the Peak PK0RE and the Hopkins nVision are clear winners. Niether require you to drill into your bumper to install the sensors. The wireless PK0RE has an even further advantage by being wireless between the sensors and the dash unit, which eliminates clutter and makes installation easier. For absolute functionality and safety, the eight sensor Napoer system is the clear choice at a bargain price. If you are ever worried about missing something in your blind spots when you change lanes, this system has you covered. If that’s too much for you and all you need is a full featured and accurate backup assist system, the Car Rover system, though a bit pricey, combines the advantages of ultrasonic sensors and a rearview camera into one convenient package.
