Wired Multifamily Home - The Rise of Automation:

Imagine driving up to your house after a long day of work. The garage door opens without touching a button. The front door unlocks – no need to fumble around for your keys – and the lights flip on. Your TV tunes to your favorite channel before you even take off your coat.

Is this a dream? No. Welcome to your automated home.
