Parking Occupancy Detector monitors outdoor and indoor parking spaces, collects occupancy status for each parking space and provides occupancy information to any parking guidance system which in turn updates the guidance displays.

The parking detector & data aggregator system has been developed specifically for outdoor parking lots. Each detector has ample battery-power built-in for seven or more years of reliable detection and status transmission. Occupancy status updates are sent via built-in radio to a data aggregator- transmitter that is equipped with a GSM modem.
