The wireless parking sensor works great. I put it on the front of my truck and it is very accurate. I love it.


Fine for front tag


If it covers the name of the state, you can probably bet to get a ticket, Check with local police or tag agency.


Helps when it works


It is good when parallel parking, or when backing out of a tight shopping center space where the aisles are narrow. However, I find it un-pairs-pairs frequently, and when it is needed, that is NOT the time to go through the re-paring process.More > < Less


Expensive and a lot of wasted time in trying to get it to work


The instructions were not clear and they varied in what they sent me for instructions compared to the manufacturers web site. The software was not working properly and the "tap button" did not work at all to bring up the app on my phone. I tried replacing the batteries that came with the unit with new Duracell alkaline batteries, and they definitely were installed correctly. Too many glitches and inability to get help. I didn't want to spend days on getting it going as it was an expensive device and there are other less expensive options. I returned it for a full refund.More > < Less

About FenSens

Smarter, Safer Ride

You don’t need a super-smart car to drive intelligently. This license plate backup sensor uses ultrasonic detection to tell you when you’re close to something.

It goes right over your license plate and pushes visual, audio, and vibration cues to your phone, alerting you when an object is close to the bumper.

Installing it is super straightforward because there’s no wiring. The included security screws are unique to FenSens, so only FenSens owners have the screwdriver to take the license plate off.

Once your frame is installed, there’s a button you can put on your steering wheel to instantly launch the FenSens app on your phone with one click. If it’s a car that different people drive, you can program it so multiple users can be connected to a single FenSens.

Your car doesn’t need to have a backup camera to know what’s behind it. This simple hack makes your car a whole lot smarter.
