Home automation is no longer a futuristic concept, but has now become expected in the homes of today. It is now a standard part of home design that greatly increases the value and efficiency of your home. The technology that has evolved from home automation is called systems integration. Briefly, it means that the HVAC, lighting, surveillance, home theater, even the video and audio systems continue to be self-contained systems, but are enhanced with simple to use control. They are still capable of being operated independently, as in the pre-systems integration days.
