What is a suitable control for regulating personnel entrance to a facility?

Turnstiles are effective physical access control devices designed to regulate the entry of personnel to a facility. They allow only one person to enter at a time, which helps manage and monitor who enters and exits the facility. By requiring individuals to pass through the turnstile, you can enforce authentication or identification procedures, such as showing an ID badge or using a keycard, thereby enhancing overall security.

The use of turnstiles is particularly advantageous in high-traffic areas where managing entry points is crucial for maintaining security. They can deter unauthorized access and contribute to a controlled environment where the flow of personnel can be monitored.

In contrast, while bollards provide a physical barrier to protect against vehicle threats, they do not specifically regulate personnel entry. A chain link fence can mark boundaries but does not provide an effective means to control access directly, and account reviews pertain more to data management and permissions rather than physical entry control. Therefore, turnstiles stand out as the most suitable solution for regulating personnel entrance to a facility.
