About Intercom Technology
An intercom (intercommunication system) is a standalone, closed-circuit system for
one-way “simplex” and/or two-way “duplex” communication. The general purpose of a
professional intercom system is to facilitate simple to complex communication setups
for a few to thousands of users who need to be continuously on talk and/or listen
mode. Two-way communication systems can operate in half-duplex or full-duplex. With
half-duplex systems, one party talks while the other party listens. With full-duplex
systems, both parties can talk and listen at the same time as if they are in a natural
conversation in person.
Users, who have different roles in a particular operation, can be in a conference or
partyline together. Or they can be sub-divided into a matrix of independent groups in
any one or many private intercom channels. In addition to establishing communication
points, intercom can also interface with third-party devices such as 2-way radios,
4-wire audios, telephone, TV cameras, AES3 digital audio, relay control (for signal
light activation or door control), etc. Coordinating activities via voice or through
third-party devices such as relay controls require low-latency (delays measured
in milliseconds).
The core technology of an intercom system could be based on one of the following
platforms: 2-wire/analog, 4-wire/digital, wireless, and IP networks. The decision
to deploy one platform over the other will greatly depend on requirements,
environment and budget. These intercom platforms operate independently or
can be integrated to form a larger system in order to address specific unique
communication workflow needs. Moreover, intercom systems can be bridged
together with different communication systems as part of a multi-platform solution.
In certain applications, intercom systems need to be geographically distributed to
support the various communication positions in a given workflow. Therefore, they
can be connected over 2-wire or 4-wire; MADI for close-distance connections such
as floor-to-floor; optical fiber for short to long distances within a building; E1/T1 for
inner-city connections; and IP networks (LAN, WAN, or Internet) for connections
across a wide area, across town, and across the country.
