Networked Door Knocker

There's a television commercial making the rounds about a new type of home security. It's a new door bell that sports a video camera and ties into your home WiFi network. This allows you to answer your door from anywhere.

In the commercial, a bad guy rings the doorbell. He's surprised to find that someone answers. Confused, he stammers, “I'm giving free home painting estimates.” The homeowner, a woman, is out and about, but she's able to respond, “I'm bathing the children right now.” Foiled, the bad guy leaves.

It's a good thing bad guys don't watch television. If they did, they might learn to recognize this new networked door bell, and the kind of things people say to give the impression they're at home. Bad guys might also start listening to the background noise to check whether it's consistent with “being at home.”

“You say you're bathing the children, but it sounds like you're at a cafe. You really shouldn't keep your front door key under the flower pot. Have a nice day!”

I can see the value in a product like this. You could remotely respond to delivery services about whether it's okay to leave a package on the doorstep. Or when you're running a little late, it could be used to tell people you've agreed to meet that you'll be home in a few minutes. You could even give out Halloween candy to trick-or-treaters from a remote location.

A networked door bell has many uses, but home security isn't one of them. Especially if you give away the game in your sales pitch. Even though the Network has thoroughly woven itself into the fabric of daily life, we seem to have no idea how it works and what it's good for. The reality is, we barely understand the real impact of the telephone yet.
