Four ultrasonic sensors mount on the rear bumper, and they are activated when a driver puts their vehicle into reverse. A drill bit for the size of the sensor is included. The beeper sounds when the sensors detect an object. The sound frequency changes base on the detect distance changing. It is very easy to install. No need to layout the wire from the control center (in the trunk) to the front cab.
