Top 5 Innovations in Home Security


If you lived in the age of Alexander the Great, your lock might have been a rope with a fancy knot to keep intruders out. Years later, the rope was discarded in favor of a heavy, wooden bar. The bar would block your door in the event that a group of ramrod-carrying men in loincloths tried to force their way into your castle.
