It is required to install a VDS guard unit in an installation with street panels. The installation, if it is video, must be developed with coaxial cable. This module must not be used without this type of cable.

This module allows you to select the active devices and establish communication between them:

Housing terminal concierge.

Plate Concierge.

Housing terminal plates.

In installations without street panels, the guard unit installation does not require the connection module.
