What is the primary function of an "access control" system?

An access control system is fundamentally designed to manage and regulate who can enter or exit a property, ensuring that only authorized individuals gain access to certain areas. This system may utilize various methods, such as key cards, biometric scans, or security codes, to verify the identity of individuals. The primary goal is to enhance security by preventing unauthorized access, which is critical in safeguarding assets, protecting personnel, and maintaining the overall integrity of the premises.

The other choices, while related to security, serve different functions. Monitoring surveillance cameras focuses on observing and recording events within a property rather than controlling access. Collecting visitor information pertains to documenting who visits the premises, which is essential for visitor management but does not inherently regulate access. Managing security personnel involves overseeing security staff and their operations, separate from the specific function of controlling entry and exit. Thus, the essence of an access control system lies in its ability to directly influence who is allowed on the property and under what conditions.
