Wireless PIR Motion Sensor Alarm System (4 pcs)

Protect your property with the Wireless PIR Motion Sensor Alarm System — a versatile 4-piece kit designed for fast, wire-free setup and reliable deterrence. Each unit combines a built-in infrared motion sensor with a loud 105 dB siren, so intruders are alerted and you’re notified the moment movement is detected.

Key Features

• 4 alarm units + 8 remote controls for flexible placement and convenient arming/disarming from multiple entrances
• Wireless operation with battery power — each unit runs on 4 AA batteries (batteries not included), no outlets or wiring required
• Detection range from 300 cm to 500 cm with a broad 110-degree field of view to cover walkways, driveways, and entry points
• Compact, durable design in ABS plastic, with an adjustable wall-mount bracket for precise placement
• Portable security ideal for driveways, garages, sheds, caravans, and seasonal properties

Why this kit stands out

Unlike wired systems, this 4-piece Wireless PIR Alarm Kit travels with you. Move it between properties or experiments with placement to tailor coverage without calling an electrician. The combination of a high-visibility 105 dB siren and a wide motion-detection range delivers rapid alerts, so you can respond quickly or deter would-be intruders before they approach. With eight remotes, family members and trusted neighbors can arm or disarm from different entry points, making coordinated protection effortless.

Ideal use scenarios

• Vehicle access areas like driveways and garages where a loud deterrent helps prevent tampering after hours
• Storage spaces such as sheds or workshops that don’t have nearby power outlets
• Temporary security for caravans, RVs, or seasonal homes that require quick setup and easy relocation
• Rental properties or campsites where simple, non-permanent protection adds peace of mind

Setup and daily use

Ready out of the box, the system requires only batteries and a quick mounting step. Install 4 AA batteries per unit, position the units at optimal angles to maximize the 110° field of view, and use the adjustable wall brackets to align them precisely. With 8 remotes, you can arm or disarm from multiple points around your property, making security access as simple as a click.

If you’re looking for a flexible, wire-free security solution for multiple spaces—especially where wiring isn’t feasible—this 4-piece Wireless PIR Motion Sensor Alarm System is a practical, scalable choice.
