No, not the kind that LOUDLY goes BEEP BEEP BEEP, incessantly.
This one senses objects behind you, when you are in reverse and has a dash-mounted small screen. Screen needs constant 12v. Sensor is wired to back up light.
It shows the distance from the object to your rear bumper (where the two sensors are mounted), from 6 feet going back to 0 feet, in feet and inches.
The screen also has an audible sound inside the coach that goes faster, the closer you get to the object.
Have just installed this on our RV and it works great.
