What is an access control system?

An access control system is primarily designed to manage and regulate who is permitted to enter or exit specific areas. This system plays a crucial role in ensuring security within a facility by restricting unauthorized individuals from accessing sensitive or restricted areas. Access control systems utilize various technologies such as keycards, biometrics, and PIN codes to authenticate users, enabling only those with the proper credentials to gain entry. This not only helps in maintaining a secure environment but also in managing the flow of people within a facility.

While options regarding tracking employee attendance, disabling alarms, or monitoring traffic flow involve elements of security or management, they do not accurately define the primary function of an access control system, which is focused on regulating physical access to locations. The distinction lies in the fact that access control is specifically about managing permissions for entering or exiting spaces, making it a central component in both physical security and asset protection strategies.
