Where and how is the video door phone installed?

Ideally, the doorbell system is to be placed where the doorbell was before. So at the entrance to the house next to the door at the upper body level. With regard to the type of installation, you can choose between surface mounting and flush mounting.

Depending on the plaster variant, you have to make a deepening in the house wall or simply drill the bracket into it. It also depends on whether you have a BUS or an IP model. For IP models, it is sufficient to connect a LAN cable and connect this cable to a PoE (Power-over-Ethernet) switch. With the 2-wire BUS system, only two wires have to be connected for audio, video, and the power supply.
