Access Control Vestibule
An "access control vestibule," also known as a "mantrap" or "security vestibule," is a small, enclosed space at the entrance of a building designed to manage access. It features two sets of interlocking doors that allow only one person to enter at a time. This setup helps prevent unauthorized individuals from following authorized people into secure areas, effectively functioning as a security checkpoint at the building's entry point.
