Basic facts about wireless intercom systems

  • Some intercom systems are portable and contain a battery. These systems can be worn by individuals and brought around the property.
  • The costs associated with installing a wireless system into a building are much lower than the costs of integrating a wired system due to the fact that integrating a wired system requires retrofitting the wiring in an existing building.
  • One potential drawback to wireless systems is that they use airwaves to deliver messages, and therefore there is a minimal chance that their messages can be intercepted. To combat this issue, however, many wireless intercom systems are encrypted.
  • In order to function at the best of its ability, a wireless intercom system is hooked up to a wireless frequency that is not already in use in the building or series of buildings that the system will be operating in. This decreases the chance that messages will interfere with one another.
