What is the function of access control systems?

Access control systems are designed to manage and restrict entry to secured areas, ensuring that only authorized personnel are allowed access. This is critical for maintaining security within sensitive environments, such as corporate offices, data centers, and other locations where restricted access is necessary to protect assets, information, or individuals. By implementing a system that verifies identities and grants or denies entry based on pre-defined permissions, organizations can enhance their security posture and reduce the risk of unauthorized access, breaches, or other security incidents.

The other options do not align with the primary purpose of access control systems. Enhancing visitor experience may be a secondary benefit but is not the main function. Monitoring employee productivity and tracking inventory levels are tasks that fall outside the scope of access control systems, which specifically focus on controlling physical access rather than managing operational efficiency or inventory management.
