Perhaps the idea could be adapted, though. How about throwing in a motion detector so that we only draw our human watchers' attention to the motion of things which look like human-sized objects? You'd need, of course, to throw in some kind of key system (RFID?) so that it's turned off whenever the rightful owners are at home, and throw in some kind of penalty (after several warnings ) to make sure people didn't leave their house guests sitting around setting off false alarms, but some form of this could make a very cost-effective alternative to more elaborate security camera systems. I'd pay twenty bucks a month for the peace of mind of knowing that nobody is breaking into my house, and that it isn't on fire.
