Comfortable: easy to install (wireless), we only need to think about one battery (the receiver is powered by the 230V mains, and the transmitter operates on a included CR2032 battery). Universal: we can mount it on a facade or a gate (IP56 provides protection against dust and water), the transmitter is equipped with a protective roof and a slot for a business card, we can install it far from home (range in open areas up to 200 m), we can choose the perfect sound (with 38 melodies and 4 volume levels), and when we mute it completely, we will still be notified of the ringing thanks to additional light signals. Modular: we can easily register additional transmitters (learning system).
