Those choosing an intercom system should seek out models that have high-quality voice communication features, the ability to transfer image, data and video, and a user-friendly interface that simplifies the process for homeowners. Units with music on hold and auto attendant can be useful for homes with outdoor gates.
Homeowners should establish a set budget before shopping for suitable intercom systems. An inspection of basic parts is also recommended to ensure the unit has a master station that controls the system, speakers that connect to the control panel and a power supply for all components of the intercom. Homeowners should check how much range they want their intercom system to have. Some units reach up to 1,000 feet, which is ideal for outdoor intercoms; however, those looking for an intercom system for use within a smaller home may not need as much range.
Those seeking to buy an intercom should also analyze the compatibility of each unit with the home or building. Some intercom systems do not delivery high-quality sound when placed near metal walls or structural obstacles that can interfere with signals. Homeowners also have to determine if they prefer a hard-wired intercom system or a wireless intercom system.
