Question: 1 / 545

What is a key function of turnstiles in a security system?

Monitor entry logs

Control access to one person at a time

Turnstiles are primarily designed to control physical access in a manner that allows only one person to enter at a time. This function is critical in environments where managing the flow of individuals is essential for maintaining security. By design, turnstiles create a barrier that must be navigated one at a time, preventing multiple individuals from circumventing security measures simultaneously. This capability helps protect spaces by limiting potential unauthorized access and ensuring that individuals passing through have been properly vetted.

While other functions such as monitoring entry logs, providing surveillance, and restricting access based on authorization are important components of a comprehensive security system, the unique characteristic of turnstiles is their ability to enforce single-person access, enhancing both security and crowd management.
