Most parking guidance systems still split detection and display into two devices. The ultrasonic sensor is fitted above the bay; the space indicator light is fitted in front of it. It works, but every bay then carries twice the hardware, twice the conduit and twice the cable, and every extra metre of containment is extra time for the installer on site.

One device instead of two

Mount the detector and the light in a single housing above the bay and the count drops from two units to one. A separate indicator light, a KBG conduit run, a single-way fitting and a network cable are no longer needed, so the cost of each parking space falls with the hardware it no longer carries.

Detection that holds when cars are parked badly

Geometry does the work here. In an integrated ultrasonic parking space detector, the centre transmitting transducer and the receiving transducer sit at a fixed, optimal angle to the horizontal plane. Reflections from the windshields of badly parked cars, the usual cause of unstable readings in conventional detectors, no longer trigger false results, and detection stays stable at a success rate of up to 100%.

For a specifier, the arithmetic is simple: fewer devices per bay, fewer cables to pull, fewer parts to service after handover.
