What are 'access control systems' designed to do?

Access control systems are specifically designed to restrict entry to certain areas. They serve a critical role in managing who can enter a facility or specific zones within it. By implementing various technologies, such as keycards, biometric scanners, or password protection, these systems ensure that only authorized individuals gain access to sensitive or restricted areas. This helps organizations protect valuable assets, confidential information, and maintain overall safety and security within the premises.

Other options, though related to security in some manner, do not accurately represent the primary function of access control systems. Allowing free entry would negate the very purpose of security measures, while monitoring employee productivity and providing surveillance footage pertain to different aspects of security and management.
