Revolutionary alarm that works anywhere and is set up in under a minute.

Minialarm doesn’t need Wi-Fi nor external power supply. The device works automatically, you don’t even have to think about it.

How it works?

No need for internet or external power supply

The alarm doesn’t stop working when internet connection is lost or a blackout happens. Four AA batteries that last for a year supply Minialarm with power, Bluetooth technology and mobile internet connection (the NB-IoT technology) is responsible for the connection.

Automatic arm and disarm function

The alarm uses the location of your phone to know when you’re at home. It arms automatically when you leave and disarms when you enter the premises.

When the movement or other sensors register movement in the guarded location, Minialarm will notify you instantly in the mobile app. And you can immediately deal with the situation.
