What is the function of a visitor management system?

A visitor management system is specifically designed to track and control which visitors are allowed access to a facility. Its primary function is to enhance security by ensuring that all visitors are logged in and out, often requiring identification and, in many cases, pre-approval for entry. This system can facilitate the screening of visitors, helping to prevent unauthorized access and ensuring that only individuals with legitimate reasons for being on-site can enter. Effective visitor management systems also often provide real-time monitoring and records that contribute to overall security protocols.

While controlling access to the facility relates to security, the visitor management system's distinct role centers on managing visitors specifically, making option C the most accurate. This system can also help improve safety protocols, as emergency evacuations can be streamlined by knowing who is on the premises at any given time.
