The DoorBird D31TDH and D31TDV door intercoms are ideal for apartment buildings and commercial properties with up to 1,000 units. With their integrated RFID and QR code reader, a virtual keypad, Bluetooth and an innovative 4D motion sensor, the models offer maximum flexibility and security.
Another highlight is the Sony Starvis image sensor with Full HD. A company logo for the phone directory, concierge call or individual background: both devices also impress with a 7-inch touch display module that can be reliably operated even when wet and can be easily replaced if necessary – a noticeable relief for installers and owners.
Thanks to the new 4D motion sensor technology and full remote configurability via app and web browser, the D31x series enables user-friendly operation and convenience in everyday life.
