The integrated module with a special sensor technology detects gestures, such as waving and approaching of the hand, at a distance of 10 centimeters and triggers a bell signal at an IP chime or indoor station. The hand gesture can also trigger a preconfigured relay which then opens the door automatically. Other actions can also be performed, for example, sending a push notification to the homeowner's smartphone or an HTTP(S) call to a building automation system, or initiating a SIP call.
The modern IP technology also enables communication with visitors via mobile devices. Homeowners can see live video of the entrance area, talk to their guests and open the door from their smartphones and tablets via the DoorBird app. With the DoorBird D2101WV, the contactless access solution has thus become a reality. The smart door intercom will go into series production in fall of 2020 and can be pre-ordered now.
