Motion sensors form the backbone of any intrusion detection system. Strategically placed throughout your home, they create invisible zones that trigger alarms the moment unauthorized movement is detected — while intelligently ignoring pets, HVAC drafts, and other common false-alarm sources.

Our standard PIR sensors detect changes in infrared energy caused by body heat, making them highly effective at identifying human intruders. For challenging environments like garages, sunrooms, or areas with temperature fluctuations, dual-technology sensors add microwave detection that requires both technologies to trigger before alarming — virtually eliminating false alerts.

Pet-immune models use advanced signal processing to distinguish between animals under 40, 60, or 80 pounds and human intruders. This means your cats and dogs can roam freely while your system stays armed, a feature essential for pet-owning households.

When motion is detected, sensors can do more than sound an alarm. Program them to trigger interior cameras to start recording, turn on lights to simulate occupancy, or send instant push notifications with the zone name so you know exactly where activity occurred.

Our technicians conduct walk tests during installation, mapping coverage areas and adjusting lens masks to exclude high-traffic areas like hallways near air vents. Wireless models communicate with your panel via encrypted signals and report low battery status well before replacement is needed.
