There is a burglar hitting houses in my neighborhood. He's tried my house, and I've caught him on my porch camera. Unfortunately it was too dark for identifiable video. He looks for unlocked doors and enters if he finds them. A sensing system that could discern my wife and I could also determine that an unidentified person in the house was a burglar, and initiate an appropriate response. Hmmm... maybe lure him into the vault with a sequence of lights illuminating the path. Sense that he's fully inside, and shut the door. Wake me up, telling me the "vault is closed", and automatically calling the police.

Now if I only had a walk in vault!

Xtremist... No reason to NOT explore the max. It's good exercise for the mind. You can sit this one out if you need to.
