Popular Home Intercom Systems
Appearance was another factor in keeping home intercom systems from becoming commonplace. Home intercom systems with a radio and voice function many times were rather large and the décor of the day was a wood grain face plate. How many people wanted a twelve by nine (12”x9”) box on their wall? Each station was usually brown or almond so if your home was mostly white or neutral they would really stand out. Wires over time would become corroded or the insulation would dry rot and short out and it was very difficult to repair them.
Since wireless technology has come way down in price makers of home intercom systems have been integrating wireless capabilities since the late 1990s. Even the master station can be wireless. Most home intercom systems have a one thousand (1000) foot radius from the master unit and you can purchase a mobile station if you want to go outside in addition to the standard wireless wall stations and speakers. If you are going wireless you will need a power source and most systems take standard alkaline AA batteries. Some manufacturers use CR123 and other photo style batteries. Keep this in mind when purchasing a new system as the need to change batteries can create a significant cost if not using AA batteries.
You can purchase simple wall mount wireless home intercom systems from a variety of stores online for as little as one hundred dollars. I found several systems with a master station and two remote stations for under two hundred dollars ($179.99).
