Tom is looking for Leo's suggestion about fire alarms and suppression. Leo went out to the local alarm company and had them do it. But there are some interesting choices that also offer full home automation with motion activated cameras that will tell the house to heat up and turn on the lights when he gets home. He can do it himself, but he'll lose the monitoring advantages.
He can create a setup that will allow him to control his home automation from his cell phone. There's also programmable thermostats like the Nest. We'll see more from CES this week.
