When mounting the sensor for occupancy detection, it’s important to keep in mind the 45-degree cone coming out of the sensor. The sensor relies on a line of sight within this 45-degree cone. Any permanently fixed objects within this detection cone will block the sensor from detecting motion beyond that object. For instance, if you have the sensor mounted above a hanging projector, it could block any motion from being detected behind the projector. If you have low hanging fixtures that block part of the cone, motion will not be detected on the other side of that fixture from that sensor.
