Your hours of operation may look a little different the week of July 4th. Whether your company is observing the holiday or extending the hours of operation, you can set up a holiday schedule to arm/disarm your system and adjust access control to accommodate the change.
"Freedom is a fragile thing and is never more than one generation away from extinction. It is not ours by inheritance; it must be fought for and defended constantly by each generation, for it comes only once to a people. Those who have known freedom and then lost it have never known it again." Ronald Reagan
