What is the primary purpose of Access Control Systems (ACS)?

The primary purpose of Access Control Systems (ACS) is to prevent unauthorized personnel from entering a designated area. These systems are designed to regulate who can enter specific locations, such as secure facilities or restricted zones, thus safeguarding sensitive information and ensuring the physical security of assets. By using various methods, including key cards, biometric scanners, or PIN codes, ACS can effectively restrict access and allow only individuals who have the proper clearance or authorization to enter.

This fundamental functionality is crucial in environments where security is a priority, as it helps mitigate risks associated with unauthorized access, which could lead to theft, sabotage, or security breaches. While enhancing productivity, monitoring attendance, or archiving security footage may be additional benefits or functions associated with access control systems, they are secondary to the core mission of protecting facilities and assets through controlled access.
