Remember when access control was limited to fitting a key into a lock and turning? You know the drill. You probably used one to lock your door this morning, and you’ll use it again when you go home this evening. Turn it one way you retract the deadbolt that holds the door closed and gains access. Turn it the other way, you fit it back into place, denying access to anyone without a key. Unfortunately, the lock and key system is an ancient innovation that is not up to the challenge of many of today’s security needs; this is where we need to upgrade to IP camera systems, electronic access cards, biometrics, and other modern technology.
