How to choose a wireless doorphone for a private house

In the first variant, all connections between the main unit and the subscriber part are made by wiring. In the second case, judging from the name, the connection between the constituent parts is formed by radio waves. Most often these are high-frequency electromagnetic oscillations above 2000 MHz. The advantages of radio communication are obvious. This is, first of all, quick commissioning and the lack of extra wiring and the associated costs of work. But there are disadvantages. This is limited in range: from 100 m to 2 km, depending on the model, as well as the possibility of interference in adverse weather conditions.
