Installation topology.
In practice there are different installation topologies for creating video door entry systems; the type of each system
in fact depends on the structure of the property, the number of outdoor and indoor stations that is desired to be
installed and the functions to be enabled.
The most recurrent diagrams are typically those where there is one or more outdoor calling stations and one
or more indoor answering stations. These outlines then differ according to the functions and services required
(connection of a number of video door entry units in parallel, bell repeaters, actuators for external services, etc.)
for which it is necessary to introduce specific supplementary modules (supplementary power supplies, external
relays, etc.).
