Crestron CEN-ODT-C-POE Dual-Technology Occupancy Sensor, PoE

A single-technology occupancy sensor either misses a person sitting still or trips on an air handler. The CEN-ODT-C-POE uses both: passive infrared for the clear heat-and-motion events, and 40 kHz ultrasonic for the small movements PIR loses, such as a hand at a keyboard behind a partition. The two together are what makes a 2,000 sq ft, 360 degree coverage pattern usable in an auditorium, a warehouse or a lobby without either false triggers or lights dropping on occupied space.

Installation is one Cat cable. It is an IEEE 802.3af powered device drawing 4 W maximum over a 10/100 Ethernet port, and it can report directly to Crestron XiO Cloud where there is no control system on site, which covers configuration, occupancy status and online/offline reporting. Front LEDs separate PIR detection (red) from ultrasonic (green) so a commissioning walk-test shows which technology is responding, with a network LED and a setup button behind the cover. The white plastic housing is low profile and fits a 4 in. octagon box or a 3-1/2 in. hole cut with the supplied template, needing 2-1/8 in. of depth behind it.
