Wireless intercoms

 

— this category includes all models in which the connection between the intercom and the calling panel is carried out via a radio channel. The main advantage of radio intercoms can be called ease of connection, because. during installation, you do not need to deal with an abundance of wires. In addition, such a device is easy to make portable. In terms of functionality, models of this type can correspond to both audio and video intercoms (see the relevant paragraphs), and the second option is much more common.
