Learn More About The Origins Of Intercom Systems

By Pierre Rossouw


Party Line Intercom SystemsThe 1960’s saw the introduction of party-line intercom systems, which were also known as two-wire intercoms. This mode of communication was hugely popular from the late 1970’s up to the mid 1990’s due to the ability of this technology to offer superior functionality at a relatively less cost. During the initial period when the party-line intercom came into existence, television production crews for synchronization of their day-to-day work activities mostly used it. From there on, it reached out to other entertainment sectors that very much needed swift communication between the crew members.

When the first intercom systems became popular, they were strung together by using parts from the old telephone systems. Until the 1970’s, these intercom systems were hard to manage. This began to change as companies began to produce more robust and reliable systems. These new systems could be easily installed, and ultimately led to their newfound popularity.

Matrix Intercom SystemsIt is said that the matrix intercom systems or in some cases known as four-wire intercoms first appeared in 1892 with the birth of the automated central office telephone switching system. A Canadian company introduced the first commercial matrix intercom used in the broadcast industry in the 1950’s, which allowed six users to communicate at any given time. Twenty years later CBC developed a new system that gave 60 users in CBC Winnipeg the ability to communicate.

In the late 1970's when the microprocessor was introduced, matrix intercom systems were made more compact and simultaneously, more productive.

Modern Intercom SystemsAs both, the two-wire and four-wire intercom systems became more advanced other intercom systems started to appear. One of these modern intercom systems is the telephone intercom system, which can send a specific signal to either your home-phone or a cell-phone. The idea behind this system is that if someone wants to enter a restricted area such as your home or office then when he or she buzzes the intercom at the locked door you can receive the signal from anywhere.

The introduction of wireless intercom systems enables the users to have communication without considering the distance as long as a compatible wireless infrastructure is present and in place. This system works hand-in-hand with the signal-sending capability of a mobile phone.

Loudspeaker intercom systems have been in existence for many years. To sailors, these systems were known as 1 Main Circuit, or 1MC for short, but store clerks commonly knew them as a general announcement system. Modern loudspeaker systems have progressed to a point where they can be custom tailored to meet the needs of a particular business or client. For instance, they can be programmed to broadcast your favorite music throughout your home.
