The concept of home security goes back as far as early humans who began the domestication of wild dogs by feeding them scraps of leftover food from meals and allowing them to share the warmth of a fire. In return, the canines would sleep at the opening of a cave and alert those inside of any approaching danger. In many cases, the dogs would also attack said intruder in an attempt to protect their meal tickets.
Today, dogs are still great at guarding things like couches and alerting their owners of the dangers of falling leaves, passing school busses, and that pesky mail delivery person who keeps stopping by. Fortunately for Fluffy and Fido, many of the other home security duties can now be handled by technology.
