Do Cats Set Off Motion Detectors?
Animals can activate motions if they are able to get in their direct field of view. This is usually the result of a poor installation. Learn more about pet-immune motion sensors.
Added:

Do Motion Detectors Work Through Windows?
Motion sensors are usually unable to detect motion through glass. The infrared energy needed to activate a motion won't easily pass through glass. Learn more about motion sensors.
Added:

Do Motion Sensors Work in the Dark?
Passive infrared motion sensors work by detecting changes in infrared energy. This allows them to work in the dark, Learn more about motion detection sensors and how they work.
