Convenient Size
After carefully researching customer feedback, we have upgraded the design of the receiver station, giving it a smaller size of just 2.8 (L) x 3.1 in (W), so that it won't block off any neighboring power sockets.
Long Operating Distance
With a reliable wireless range of 1,000 feet and strong signal , the doorbell will never fail to alert you when someone shows up at the door. Enjoy a reliable and hassle-free doorbell system at home, in factories, offices, classrooms, apartment blocks, villas, and other large areas.
IP55 Waterproof
IP55 waterproof and functional between -4 °F to 140 °F, the doorbell can operate in even the harshest weather conditions.
Music to Your Ears
The doorbell boasts an ample selection of 52 melodies from traditional doorbell chimes to jingles, certainly offering a chime that suits your taste.
Memory Function
Thanks to its smart memory function, it remembers your previous set melody and volume level - even after a power outage.
Mute Mode
The silent volume level doesn’t disturb a sleeping baby and the maximum level of 115 dB is hearable by the hearing-impaired or even during a party.
