Motion Detectors
When placing motion detectors, anticipate traffic patterns:
§ The lanes of traffic most used by people in your home are also those most likely to be used
by intruders
§ Foyers, stairways, hallways, and entrance-ways are excellent locations for a motion detector.
§ Do not place motion detectors at the end of hallways where an intruder will be walking
directly toward or away from the detector. For best coverage, mount the motion so that the
likely direction of intruder motion is across the motion detector’s pattern.
A motion detector facing the following can cause false-alarms or failures in detection:
§ Direct sunlight
§ Cold drafts
§ Windows
§ Uninsulated walls
§ Heat sources such as fireplaces and heating vents
§ Moving objects such as fans
§ Air conditioning vents
§ Glass furniture
§ Obstructions such as curtains, plants, large furniture, doors
Note: Free roaming pets pose special problems for motion detectors. Your installer has been trained
to help you configure your installation to address your specific pet needs.
