Reliable wireless PIR motion sensor designed for security monitoring and automated alerts. Operates on 319 MHz frequency with passive infrared detection and a 35foot detection range. Compact and lightweight for flexible placement, and supplied with all mounting hardware plus a detailed installation manual for straightforward setup. Key benefits Accurate motion detection: Precise passive infrared sensing detects heat signatures and movement to reduce false alarms and focus on activity. Wide coverage: Up to 35 feet detection range covers doorways, corridors, and common entry points without the need for wired connections. Wireless compatibility: Uses 319 MHz frequency, suitable for integration with security systems and receivers that operate on the same frequency. Easy installation: Includes comprehensive mounting hardware and a clear installation manual to speed setup and correct positioning. Flexible placement: Compact footprint and lightweight construction allow placement on walls, ceilings, or other mounting surfaces where space is limited. Product features and specifications Detection technology: Passive infrared (PIR) for immediate transmission of motion events Frequency: 319 MHz wireless operation Detection range: Up to 35 feet Size: 8.0 x 4.0 x 6.0 inches Weight: 12 ounces Package contents: Motion sensor, complete mounting hardware, installation manual How this product solves common problems Eliminates wiring constraints by using a wireless signal on 319 MHz, simplifying installation in retrofit and remote locations. Reduces time spent tuning and repositioning with precise PIR sensing and clear installation guidance included in the manual. Offers flexible deployment where space is limited thanks to its small size and low weight. Typical use scenarios Residential entry monitoring: Install near front and back doors or in hallways to detect unauthorized entry and send alerts to a compatible receiver. Garage or outbuilding protection: Provide motion monitoring in detached structures without running cables, using the wireless 319 MHz link. Commercial interior monitoring: Place in retail stockrooms, office corridors, or storage areas to extend coverage of an existing wireless security setup. What to check before Confirm that your security system or receiver supports 319 MHz wireless devices for compatibility. Verify mounting surface and placement to ensure the sensor can achieve the required line of sight for PIR performance. This sensor provides a compact, wireless solution for motion detection where precise PIR sensing, a 35foot range, and simple installation are needed.
