Researchers at the Fraunhofer Institute have combined and adapted all the cameras, buzzers, keypads, motion detectors, RFID readers and intercoms into a wireless integrated door station and combined it with the door handle which can integrate existing and planned infrastructure at low cost and high convenience.

The system uses a wireless power supply – for instance via the door opener when the door is closed. The data transmission works in a similar way. Nothing need be replaced except the door handle and the lock casing. Sheathed inside them – protected against violence – are the doorbell, a camera, an intercom, and if required a motion detector or an RFID transponder system for access control.

As a result, authorized persons no longer need a key. The door handle identifies the code of the inexpensive chip with the aid of its transponder antenna.
