Keypads in each room that can control anything from speakers in every room, lighting, alarm system, and even air conditioning and electric shades is an excellent addition to any new home. New units available that can do multi-source, multi-room allow the user to change a CD that is playing in the bedroom while listening to the radio in the kitchen. The same keypads can also dim the lights, and change the temperature in the theater, while lowering the shades, and dropping down the projection screen and starting the movie, all with the touch of one button.
