DoorBird D31 Door Intercom System

The D31TDH and D31TDV 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 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.

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.
