If someone is tailgating how exactly will a mantrap help? wouldn't CCTV be more of a safety procedure to identify the tailgater?


A man trap is usually a set of double doors and a guard between them. The guard checks credentials . Therefore having someone checking id before entering the building would prevent tailgating more than just filming it happening.


Mantraps can also be made in a way like a subway entrance, where only one person can enter at a time because the turnstile only rotates just enough.
