DUAL TECHNOLOGY PRESENCE 360
UT-964i integrates passive infrared (PIR) sensor and ultrasonic sensor (US) technologies. It takes advantage of the best features of both sensors. PIR sensor is immune to noise signal and airflow; Ultrasonic sensor is immune to high sensitivity (able to detect small movement) and it doesn’t require an unobstructed line-of-sight view between sensor and occupant.
The dual technology detector can provide reliable performance to minimise the risk of false triggering.
