This particular WiFi alarm-siren is a truly smart device. In addition to its basic capabilities, it has a very important advantage: it can also function as a HUB. You can connect sensors and other alarm devices to it. Thus, you can connect a motion sensor, a door or window sensor, or even a smoke sensor to this alarm-siren, which, when detecting anything suspicious, can automatically activate the siren.

As a SMART alarm-siren, when activated, you will receive a notification on your mobile phone. Additionally, the loud sound of the siren will scare off anyone trying to enter your home. The smart siren also has an interesting feature: it can be used with a smart noise, so that when someone rings the doorbell, you will receive a notification on your phone and the siren will activate a short "dingdong" sound.
