A mantrap, security mantrap portal, airlock, sally port or access control vestibule is a physical security
Physical security describes security measures that are designed to deny unauthorized access to facilities, equipment, and resources and to protect personnel and property from damage or harm (such as espionage, theft, or terrorist attacks). Physi ...
access control
In physical security and information security, access control (AC) is the action of deciding whether a subject should be granted or denied access to an object (for example, a place or a resource). The act of ''accessing'' may mean consuming ...
system comprising a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens. Airlocks have a very similar design, allowing free ingress and egress while also restricting airflow.
In a manual mantrap, a guard locks and unlocks each door in sequence. An intercom and/or video camera are often used to allow the guard to control the trap from a remote location.
In an automatic mantrap, identification may be required for each door, sometimes even different measures for each door. For example, a key may open the first door, but a personal identification number
A personal identification number (PIN; sometimes RAS syndrome, redundantly a PIN code or PIN number) is a numeric (sometimes alpha-numeric) passcode used in the process of authenticating a user accessing a system.
The PIN has been the key to faci ...

readers or iris recognition scans. Time of flight sensors are used in high security environments. Newer stereovision detection systems are often employed.
Some security portal mantraps use dual authentication, employing two separate readers (security card plus biometrics, for example). This is very typical in the data center security entrance control environment.
Security mantrap portals typically offer options for all steel construction and BR (bullet/ballistics) or RC (burglar protection) construction including thick laminated curved glass.
Metal detectors are often built in to prevent the entrance of people carrying weapons. This use is particularly frequent in banks and jewelry shops.
Turnkey systems are sometimes provided by some suppliers due to the need for specially trained installers.
Fire codes require that automatic mantraps allow exit from the intermediate space while denying access to a secure space such as a data center or research laboratory
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratories are found in a variety of settings such as schools ...
