Wired Dual-Tech PIR Microwave Motion Sensor | Pet Immune
Wired Dual-Tech PIR & Microwave Motion Detector — Wall-Mounted Home Security Sensor
Upgrade your home security with this intelligent wired dual-technology motion detector that combines passive infrared (PIR) sensing with K-band microwave detection. By requiring both technologies to trigger simultaneously, this sensor dramatically reduces false alarms caused by temperature changes, air currents, or outdoor interference — giving you reliable, confident protection around the clock.
Designed for easy wall-mounted installation, this detector is ideal for indoor security systems in homes, offices, and small businesses. Its built-in pet immunity feature (up to 10 kg / ~22 lbs) means your cat or small dog won't set off your alarm — only genuine intruders will.
Key Features
- Dual-Technology Detection: PIR infrared sensor combined with K-band (10.125 GHz) microwave detection for highly accurate motion verification
- Excellent False-Alarm Suppression: Both sensors must agree before triggering an alarm, minimizing nuisance alerts from environmental changes
- Pet Immunity: Ignores animals weighing under 10 kg (~22 lbs), keeping your alarm system calm while your pets roam freely
- Temperature Compensation: Built-in circuitry maintains consistent performance in both hot and cold environments (-15°C to 55°C)
- Microwave Anti-Interference: K-band microwave technology actively suppresses interference, enhancing detector sensitivity
- Durable ABS Housing: Impact-resistant casing built to withstand everyday handling and installation
- Wide Detection Zone: Covers up to 7.6 m × 7.6 m (25 ft × 25 ft) — ideal for living rooms, hallways, and entryways
- Anti-Tamper Switch: Built-in tamper switch alerts the system if the unit is removed or opened
- Quick Installation: Simple wired connection with straightforward mounting hardware included

Frequently Asked Questions
Q: What makes a dual-tech PIR and microwave motion detector better than a standard PIR sensor?
A: A standard PIR sensor triggers on any infrared heat movement, which can lead to false alarms from sunlight shifts, HVAC drafts, or outdoor animals. A dual-technology (PIR + microwave) detector requires both the infrared and microwave channels to detect movement simultaneously before triggering the alarm. This cross-verification dramatically reduces nuisance trips while maintaining excellent detection accuracy for genuine intruders.
Q: Will this motion sensor trigger if my cat or small dog walks through the detection zone?
A: This detector features built-in pet immunity for animals weighing under 10 kg (approximately 22 lbs). Pets below this weight threshold should not trigger the alarm under normal installation conditions. For best results, mount the sensor at the recommended height and angle per the included user manual.
Q: Can this wired motion detector work with my existing alarm system?
A: Yes — this is a wired sensor that connects via standard N.C. (normally closed) relay contacts, making it compatible with most conventional and hybrid wired security control panels. The working voltage range of 7.5V–16V DC also covers the majority of common alarm system power outputs. Always verify your control panel's input specifications before installation.
Q: Is this motion detector suitable for outdoor use?
A: This detector is designed for indoor use only. Its operating temperature range (-15°C to 55°C) and humidity tolerance (up to 95% RH) make it adaptable to varying indoor climates, but it is not weatherproofed for direct outdoor exposure. For outdoor perimeter protection, a dedicated outdoor-rated sensor is recommended.
