What do you need to install a working system?

Theoretically, a compact door station as well as a monitor are sufficient and have all the elementary features that are needed for the door station to work. However, the customization options are very extensive if you configure a doorbell system yourself.

However, devices for connectivity such as a 2-wire BUS module for the 7-inch monitor or a PoE (Power-over-Ethernet) switch for the IP connection of 10-inch monitors are also of elementary importance.
