Wireless intercom systems and how they work

An intercom (intercommunication device), talkback or door phone is a stand-alone voice communications system for use within a building or small collection of buildings. It’s a two-way communication electronic device that contains circuitry for the purpose of transmitting and receiving audio and/or video transmissions. Intercom allows a person speaking into a microphone to be heard on a speaker by people in a different room or area.

Intercoms come in a variety of styles. Some are extremely easy to use while others can be very complicated. There are audio intercoms, video intercoms, as well as multi-tenant intercoms.


A wireless intercom system is an electronic piece of equipment that allows people to communicate via radio waves. Wireless intercom systems are manufactured in numerous styles and designs. Some intercom systems are advertised as a wireless system. However, their communication capability is accomplished through AC electrical building wiring.


There are a variety of wired intercom systems that require wiring throughout the walls that extend from one room to another for them to work. However, wireless intercom systems are easy to install because they have no wires that connect the intercom units.

Therefore, a wireless intercom system can be installed and working within minutes of taking the unit out of the box. Some wireless intercom systems consist of one or more channels. When there is more than one channel, conversations can take place by linking several intercoms.

With wireless intercom systems, conversations can also be heard by people within a certain range who have devices such as baby monitors, scanners, cordless phones or similar wireless intercom systems.

Conversations can be heard due to the use of unrestricted public wireless frequencies. However, privacy can be attained for wireless intercom systems when the auditory stream is encrypted.

There are also manufacturers who make wireless intercom systems already equipped with encryption to be used by the sports industry, military, and various corporate customers.

Wireless intercom systems are very convenient and make it very easy to communicate with family members from one room to another while eliminating all the shouting. They generally have a communication range of about 1000 feet. They are an easy and convenient method to communicate with or monitor a loved one in an entirely different room in your home. They are excellent for people who are confined to a bed or wheelchair and need to communicate with the person caring for them.

Wireless intercom systems are also used in offices. In an office setting, you can communicate with a co-worker in a different office without ever having to move from your chair. Wireless intercom systems can be two-way intercom systems or one-way audio intercom monitoring systems and because they are wireless the monitor for wireless intercom systems can be conveniently transferred to any room in the home or office. Wireless intercom systems can be placed on a desk or mounted on a wall. Some wireless systems are made for indoor communication use and some wireless intercom systems are used for extended range outdoor communication.
