Precision motion sensors use passive infrared (PIR) detection to analyze changes in heat and movement, while refined optics, pet immunity, temperature compensation, and motion-recognition algorithms help distinguish people from animals or other disturbances. Dual-technology sensors require both PIR and microwave detection to identify motion, while advanced signal processing and quad-element sensing can help filter environmental activity, such as swaying vegetation, changing light, or outdoor conditions.

For indoor applications, choose wall-mounted or ceiling-mounted passive infrared sensors, including options with pet immunity, temperature compensation, 360-degree coverage, or dual-technology detection for challenging spaces. Outdoor and perimeter applications are well suited to weather-resistant PIR sensors and IP-connected quad-element detectors with adjustable beam ranges, programmable outputs, and integration with cameras or lighting.

Precision motion sensors may be mounted on walls, in corners, on ceilings, or outdoors for perimeter monitoring, depending on the sensor design and application. Review the detection angle, coverage area, beam range, mounting height, and potential obstructions, and use adjustable settings or masking where available to help limit unwanted activity from pets, trees, sunlight, or neighboring zones.

Precision motion sensors may connect to wired alarm panels, request-to-exit circuits, or access control systems through sensor outputs, while wireless models communicate with compatible security panels using encrypted or two-way wireless technology. IP-based sensors can use Power over Ethernet (PoE) and network connections to integrate with video management systems, cameras, lighting, and other connected devices.
