security gates
Access control portals
Security gates are barriers controlling access to restricted areas—building entrances, parking lots, gated communities, or airport checkpoints.
They range from simple swinging gates requiring a key to sophisticated systems with keypads, card readers, or biometric scanners.
The term also covers metal detectors at airports and public venues: We had to pass through security gates before entering the stadium.
