Wireless Motion Sensor Alarm

This wireless infrared motion sensor alarm delivers a 125dB siren for home, garage or van security. It operates on AAA batteries or USB rechargeable power for flexible placement. The unit uses PIR detection with intelligent analysis to reduce false alarms. A 328ft remote control provides arming, disarming and emergency SOS functions.

Two Operating Modes

Daytime doorbell mode offers adjustable volume at 80dB, 100dB or 125dB to alert occupants without excessive disturbance. Nighttime alarm mode activates the full siren to deter intruders. The PIR detector covers a 40ft range for broad area monitoring. No wiring is required, freeing installation from mains constraints.

Upgrades Basic Alarms

This system replaces simple entry chimes or unmonitored sensors with remote-controlled arming and a 328ft control range. The jump is worth it when you need adjustable volume modes and a dedicated SOS button for immediate alerts. It is not suited for buyers who require smart-home integration or app-based notifications.
