There are what seems to be an endless array of systems to choose from. The purchaser is faced with decisions of whether to purchase wired or wireless; 2-wire, 4-wire, or Cat-5; video or voice only; full-featured or basic features only. You can even purchase systems that transmit and receive over your house or business power lines.

Which system is right for you depends on a number of factors that we will help guide you through.

When shopping for an intercom system you'll see both the terms door phone and intercom used. What’s the difference between a door phone and an intercom? These terms are often used interchangeably, even in the same product description. For this guide, the term intercom will be used for systems inside a building that enable you to call from room to room.

A door phone is a system that enables you to receive “calls” from your front door or some other door on the outside of your building. When someone arrives at an outside door, they press a button that alerts one or multiple inside stations and then the people inside the building can talk to them by pressing a button on an inside station. Intercom systems may also have an outside intercom, or what we call a door phone.

A video door phone enables you to actually see who is at the outside station as well. Video adds another layer of security to your door phone.

Another type of intercom is the baby monitor. These are one-way intercoms. You can listen to the baby but you can’t talk back (except for our WireFree unit). These units are almost always wireless. You can even get video baby monitors that see in the dark.
