No, FenSens is by far the easiest backup parking sensor technology on the market and it doesn't require any wiring at all. Simply replace your old license plate frame with the customizable FenSens smart license plate frame, install the free mobile application, and pair the device. It will work seamlessly every time you want to backup thereafter.

The FenSens can detect objects about 10 feet away and guide you safely to less than 1 foot away from them. When an object is detected, the response is very quick, but please pay attention to any feedback warnings and always back up carefully. While FenSens helps assist in safe parking, please pause for one second, look behind to see if your path is clear, then move.

FenSens is perfect for all consumer and commercial fleet vehicles not exceeding 30 feet in length. If your car has a recessed license plate frame above the bumper, you might need the FenSens Truck version, which has the sensors positioned at the top of the FenSens device. We advise the owner of any vehicle with a license plate frame higher than 4 feet off the ground to test the vertical range of the sensor before using, as it may have trouble seeing objects below 2 feet.

Multiple users can be connected to one FenSens device. The original account holder can go to "Manage Devices" from in their settings menu, click on the device, and copy the share code to send to friends and family. While signing up the friends or family input that code during "LOGIN". 

When using the device the TAP QuickLaunch button will work for the registered user that connects to it first. For Android, whoever is in range first will be prompted and capable of launching the app on their phone when the TAP button is launched. For iOS both users will receive a push notification when in range of the device, whoever hits the notification to connect first will auto-launch the app on their phone.
