You can place the motion detector on a counter top or use the included mounting bracket. The bracket lets you swivel the motion detector for the best coverage.

Note: The motion detector senses mo- tion by detecting temperature chang- es. To help prevent false alarms, do not place the motion detector near a heating or air conditioning vent.

Secure the bracket to the detector’s bottom using the supplied machine screw. Then secure the bracket to the wall. Finally, loosen the screw on the hinge and adjust the detector to be lev- el, then tighten the screw to hold the detector in position.

For the best coverage, place the mo- tion detector at a height of 6 feet, then position the lens so an intruder walks across its path rather than toward it.
