What is the primary function of security technology like access control systems?

The primary function of security technology such as access control systems is to monitor and restrict entry to specific areas. These systems are designed to manage who is allowed access to certain spaces based on predetermined criteria, enhancing overall security by ensuring that only authorized individuals can enter. By utilizing mechanisms such as key cards, biometric scans, or PIN codes, access control systems effectively prevent unauthorized entry, thereby protecting assets and individuals within the secured area.

While enhancing the presence of security personnel can be a benefit of implementing these systems, it is not their primary function. The role of a deterrent is also an important consideration, but access control systems are primarily focused on the active management of entry. Ultimately, while technology can support security operations, it does not replace the critical judgment and presence that trained security personnel provide.
