This is a perfect example of how a 15,000sqf home should be controlled. ONE screen does it all!! Who needs a tv in the Kitchen, use the Touchscreen. What some one at the door? No problem the doorbell rings through all the music speakers in the home, go to a touchscreen view the person at he front door, Push the button that says "Welcome" and have the pool fountains start, lights got to the perfect settings, Air Conditioner kicks on, fireplace starts, music comes on lightly, theater turns on. You are ready fot the perfect party. OH DID WE MENTION YOU CAN DO THAT OUT OF TOWN FROM YOUR IPHONE, OR IPAD????
