Specifications - STI Rex Plus II User Manual

CAUTION
Rex Plus II is designed to detect moving objects though a wall or door and designed to be placed in an area
®
hidden from an intruder or guest. The unit may have reduced sensitivity at the back of the unit. If sensing
movement from behind, try to change the position of Rex Plus
The sensitivity control can also be reduced to minimum to detect in the desired direction while reducing
the undesired detections. Moving objects, in addition to people, can also be detected, including vehicles,
animals, trees and shrubs blowing in strong winds and dwelling movements during strong storms.
