The Siedle App 2.0 for the Smart Gateway can be accessed over the mobile phone and it comes with the new, innovative user interface design. The Siedle app turns the mobile devices into a mobile extension to your door communication. Its functions correspond to those of a Siedle indoor station. It receives the door call, provides a live video image, establishes a speech connection and opens the door.

As soon as an internet connection is established and the app is active, the door call can be received, the video image displayed and a speech connection established - anywhere the world over, wherever an adequate mobile phone network connection exists.
