The Dolphin Motorhome Rear Parking Sensor Audio kit comes with 4 sensor heads to be mounted into the bumper of your pride and joy. It is equipped with extended 6m Parking Sensor Leads and an extended 10m Power Lead. This enables you to route the sensor leads around the width of the bumper and bring the interface box further into the vehicle, should you need to.
The audio buzzer starts to beep at 1.5m and gets progressively faster, the closer you get to the obstacle behind. This becomes a solid, unbroken tone, at 30cm enabling you to get into the tightest of spaces with confidence. The audio buzzer is very loud, so should be fitted away from the driver and passengers.

All of our parking sensors come with a swap socket feature. This enables you to unscrew the sensor head from the sensor lead. So if you ever need to swap the sensor head, due to damage or a fault, this becomes an easy job that takes minutes. No bumper removal and no re-routing of cables required.
How Do Ultrasonic Parking Sensors Work ?
Dolphin Van Parking Sensors work by radiating ultrasonic beams from each sensor head. These beams travel outwards in a 60 degree cone shape (30deg up, 30deg down, 30deg left, 30deg right). When these beams hit an obstacle behind, they are bounced back to the sensor heads and are registered by the interface box. The distance is calculated based on the length of time it took the beam to return to the interface box.
The parking sensors pick up their power from the reverse light, so when you go into reverse the parking sensors come on. They start to sense obstacles from 1.5m and at this point will emit slow frequency beeps. The frequency speeds up the closer you get to the obstacle behind, until you get to 30cm. At this point, the beeps will become a solid unbroken tone indicating you should stop.
