Wireless home motion detectors connect to a compatible security hub or control panel over a designated wireless protocol, then send motion, tamper, and battery status alerts to the system. During setup, an installer enrolls the detector, selects settings such as coverage and pet immunity when supported, and positions it to monitor rooms, entryways, or other protected areas.

Passive infrared (PIR) home motion detectors sense changes in infrared energy, such as body heat moving across the detection area, while dual-technology detectors combine PIR with microwave sensing. A dual-technology detector typically signals an alarm only when both sensing methods detect activity, which can help reduce false alerts in demanding indoor environments.

Wall-mounted home motion detectors support wall or corner installation and can offer selectable pet immunity, making them a flexible choice for rooms with defined entry paths. Ceiling-mounted detectors provide discreet, overhead coverage, with some models offering 360-degree detection for broader room coverage or larger open areas.

Home motion detectors may use selectable pet immunity or pet-targeting algorithms to help distinguish people from animals, while dual-technology sensing and digital temperature compensation can help limit alerts caused by environmental changes. For outdoor areas, multi-sensor detection and signal processing can help differentiate people from small animals, swaying trees, rain, sunlight, and changing light levels.
