What You Get The Dolphin 24 volt display kit is a 4 recess mounting sensor high quality system that will cover the widest of large commercial style vehicles including trucks and lorries giving a professional finish. Included with the 4 recess sensors is a combined digital display and buzzer which gives audible bleeps with increasing frequency as you get closer to an obstacle and a digital countdown in cm (there is an on/off switch for the buzzer) (there is an on/off switch for the buzzer).
How it works The system works by radiating ultrasonic beams covering the area behind the vehicle. The beams are reflected by obstructions behind the vehicle, and re-enter the sensors. The reflected beam information is processed to calculate the distance of the obstruction.
As with the other systems the Dolphin unit is activated when reverse gear is engaged. As the vehicle is reversed. When the vehicle is less than 1.5 metres from the obstruction the audible alert will emit intermittent bleeps. As the vehicle gets closer to the obstruction the frequency of the bleeps increases. At 30 centimetres from the obstruction the bleeps become a continuous solid tone.
