Access control covers both physical systems (gates, fobs, keypads, turnstiles) and procedural steps (visitor sign-in, credential checks) used to limit who can enter a site or specific area of it.
In CPTED terms, access control is meant to funnel legitimate users through defined, observable points rather than allow undefined movement across a property, which also supports natural surveillance and territorial reinforcement.
Access control is only as strong as its weakest routine — propped doors, shared codes, and unchallenged tailgating are common ways a well-designed system is defeated in practice.
