The system uses U-Spot M2M sensors and a parking app through which users check into the space. An alert is triggered if the user doesn’t check-in or if the time defined is exceeded. When the vehicle leaves or the infraction is dealt with by the guard, the alert is deactivated and saved. Urbiotica says the system is autonomous, reliable and robust. Additionally, it is easy and affordable thanks to the U-Spot M2M sensors, with no need of a Gateway.
