Intercoms can have a variety of functions in home or business settings. There are wired and wireless video intercoms as well as intercoms which solely transmit audio and ones which transmit video as well as audio. You can also choose a system which is expandable meaning you would be able to add more indidivual intercom units to the overall system.

People can use their intercoms in a variety of ways, whether it is as a baby monitor, a doorbell or just a convenient way of communicating through the home or office without having to yell. Intercoms are becoming easier to install and operate every day with most intercoms purchased now being wireless and capable of being setup and installed in minutes.

Your typical wireless intercom system should work using digitally secured radio links to stop any eaves dropping. There should also be outdoor units available for the system which are weatherproof and wireless ranges of up to 1000 feet are not uncommon.

A video door intercom like the Optex IVision is a great way to manage and protect the front entrance to your home. Using these video door phones you can quickly see who is at the door before you even decide whether or not to communicate with them let them know you are home.
