The selling point is that you can monitor all this stuff remotely on your phone, but really, what can you do about it? I don't see how this surpasses the (very expensive) services like Brink's and ADT who will contact law enforcement for you.
And yes, I've seen the ad where the guy is at the store trying to figure out what to buy and can look in his fridge from his phone. Whatever happened to making a grocery list before you leave?
