A motion-based entry alert with genuine expansion room, worth choosing specifically because it detects a body moving through a zone rather than a door swinging open.

Overview
A battery-powered motion sensor paired with a plug-in receiver, meant to sound when someone passes through a doorway rather than when a door itself opens. Aimed at store entries, offices and rooms where you want a heads-up on foot traffic.
Unlike a magnetic contact sensor, this unit watches an area: Amhey specs the detection zone at roughly 16 to 26 feet across a 110 degree spread, with a separate 500 foot wireless range between the sensor and the receiver. That distinction matters for placement, it belongs near a doorway looking into the room rather than stuck to the door edge.
- 16-26 ft motion detection at 110 degrees
- 500 ft wireless range to receiver
- Expandable up to 20 sensors
- LED visual alert plus 110dB audio
Who it's for
Works for a retail owner who wants to know when a customer enters without a strict door-contact setup, or a household watching for an elderly relative getting up or leaving a room. Less suited to someone who wants a simple door-open trigger, since a person can walk past without tripping the zone if it is placed wrong.
Pros and cons
- 110 degree motion detection zone up to 26 feet
- Expandable to 20 sensors and multiple receivers
- LED flash alert alongside the audible tone
- 32 tunes across 5 volume levels including silent mode
- Motion based, not a magnetic door contact
- Placement affects accuracy more than a simple door sensor
- 2x AAA batteries needed per sensor
Performance notes
The included motion sensor covers a 16 to 26 foot range in a 110 degree arc and sends a signal up to 500 feet to the plug-in receiver, which tops out at 110dB with an LED flash for a visual cue alongside the sound. The system is built to expand: Amhey rates it for up to 20 sensors and an unlimited number of receivers on one setup.
