This wireless doorbell uses a receiver that plugs into power and a magnetic door sensor that alerts when the two parts separate. That makes it practical for front doors, side doors, windows, and other entry points you want to monitor more closely.

The 433 MHz signal and 150 meter open-area range give you reliable coverage in everyday spaces. It is a simple way to add awareness without running wires or changing the room.

With support for multiple receivers and sensors, you can shape the system around your space instead of working around it. That makes it a better fit for homes, apartments, offices, shops, and warehouses where one alert point is not enough.

Keep every important entry on your radar with a door chime that is simple to place and easy to hear.
