Authentication is a technique used to verify that someone is who they claim to be. Authentication with an additional layer of authorization in which it is determined if a user should be allowed to access.

6 Reason to Have an Access Control System in Place

  • Safety. Access control systems allow you to provide a safe working environment for your employees.
  • Grant limited access to any high risk or stock areas without increasing the risk for internal theft or damage to assets and inventory.
  • Peace of mind. Every time access is granted to your property or data system, it is logged and recorded for later review if necessary.
  • Remote Access. One of the most convenient benefits of access control, your system can easily allow you to let in individuals when you are not there. No matter where you are located, access control systems can provide access to your busi-ness remotely, and you will always know who is coming and going.
  • Misplaced Keys. Eliminate the worry of tracking who has keys or if reproductions have been made. Swipe cards or biometric access can be granted and revoked using the date system keeping unwanted intruders or unauthorized access
  • Customize Individual Schedules. Access control systems allow you to minimize your exposure to risk by never granting more access than is absolutely required for each specific user and in any given situation.
