Wireless PIR Motion Sensor Alarm – Outdoor Perimeter Security

Wireless PIR Motion Sensor Alarm – Portable Perimeter Security for Home, Camping & Outdoors

Stay secure wherever you are with this compact, easy-to-use Wireless Infrared Motion Sensor Alarm. Powered by PIR (pyroelectric infrared) technology, it instantly detects movement within a wide 120° sensing angle and up to 5 metres away — then blasts a 125-decibel siren to deter intruders and scare off wildlife. No wiring, no complex setup: simply place it, switch it on, and enjoy peace of mind at your campsite, home, garden, shop, or fishing spot.

Made in Mainland China.

Key Features

• Powerful 125 dB Siren: A loud, attention-grabbing alarm that effectively deters unwanted visitors — human or animal — the moment motion is detected.

• Continuous Alarm Duration: Sounds for up to 8–10 hours when triggered, ensuring sustained deterrence.
• No Installation Required: Compact ABS body (7.7 × 5 × 2.4 cm) can be placed on a surface or suspended from a hook — takes seconds to deploy.
