PRESENCE INDICATOR TRUE PRESENCE COM1 UP IP20 BL

True Presence, an absolute presence detection technology based on high-frequency techniques (HF 7.2 GHz), detects micro-movements of breathing in the body and is suitable for monitoring presence and absence indoors. In motion detection, True Presence sensors detect both perpendicular and transverse motion directions with equal effectiveness. The high-frequency signal penetrates light wall materials. True Presence sensors are also suitable as motion detectors for monitoring high-bay warehouses up to a height of 12 meters. Warm air currents caused by heaters in warehouse and data center environments do not cause false triggers for HF detection.
