Active Infrared technology (IRA)

This technology uses the infrared invisible light which is emitted continuously. It can operate in various ways: photocells, distance measurement with background suppression, triangulation and analysis of the background ... In this case; the sensor lights up one or several areas and analyzes the energy in return. A significant difference compared to the original picture triggers the detection.This technology ensures the detection of the presence for the protection of persons or vehicles close to the door. It comes as w stand-alone sensors or as combined sensors.
