If your business has a large-sized staff or if you have regularly scheduled maintenance workers entering your building, this is certainly something that you should to consider. Regardless, you can install an access control system that will enable your employees to have secured entry between regular hours of operation. Additionally, maintenance workers can get clearance on specific weekends or time frames during the week. This way, you will be able to keep all of your doors locked electronically and securely without any weekend or holiday access.
