Implementing an access control vestibule provides a physical barrier that requires individuals to pass through two sets of interlocking doors and verifies their identity before entry. This method is highly efficient at preventing unauthorized access by tailgating. While video surveillance and motion sensors can help monitor entry and exit points, they are less effective at actively preventing unauthorized access. Security guards are also valuable but can be circumvented if not vigilant at all times.
