Overview
A wireless magnetic contact sensor and plug-in receiver pair, built to sound an alert whenever the monitored door or window opens. Suits home entryways, small shop doors and back rooms where staff need a heads-up when someone walks in.
The sensor half runs on a single AAA battery and is designed for low power draw, so Metak rates it for roughly one to two years before a swap. The receiver plugs into any outlet and offers 58 selectable chimes across five volume steps, including a mute setting for spaces that do not want a sound.
- 500 ft rated wireless range
- 58 chimes, 5 volume levels plus mute
- Runs on one AAA battery
- Plug-in receiver, no wiring
Who it's for
Fits a homeowner who wants a simple door-open alert for a child's room, basement or side entrance, and a shop owner who wants to know when a customer steps in. Not built for multi-door commercial coverage beyond what one transmitter and receiver provide out of the box.
Pros and cons
- Pre-paired transmitter and receiver, no syncing step
- 500 foot rated range between sensor and receiver
- 58 chime choices with 5 volume levels plus mute
- Single AAA battery rated for 1-2 years
- No app or smart home connection
- Contact sensor only, does not detect motion in a room
Performance notes
The transmitter and receiver ship pre-paired, so setup is attaching the sensor to the door frame and plugging in the receiver, then picking a chime and volume. Metak lists a 500 foot working range between the two units and a maximum output of 120dB, loud enough to carry through a house or small storefront, with a mute option for quieter settings.
