Antitailgatingfunksjoner

Antitailgatingfunksjoner are features within access-control systems designed to prevent tailgating, the act of an unauthorized person following an authorized user through a secure entry point. The term is used in security engineering and facility management to describe measures that reduce the risk of unauthorized access in offices, campuses, transit hubs, data centers, and other secured areas. These functions can be implemented through hardware, software, and policy controls working together.

Typical mechanisms include physical barriers such as turnstiles, speed gates, and mantraps that enforce single-person passage. Electronic door controls with sensors and anti-passback rules prevent a single credential from being reused by multiple people. Biometric or multi-factor authentication may be required at points of entry, and software monitors entry events to detect unusual patterns. Some systems incorporate video analytics to identify tailgating incidents, triggering alerts or automatic lockdown when necessary. In some contexts, anti-tailgating features are extended to vehicle access with gate interlocks and vehicle-detection sensors.

Deployment considerations center on security requirements, throughput, and accessibility. Effective antitailgating depends on reliable hardware, accurate event monitoring, and clear policies for escalation of suspected incidents. Privacy and user convenience must be balanced to avoid excessive false alarms or inconvenience for legitimate users. Regular maintenance, calibration of sensors, and integration with broader identity management systems are important for sustaining effectiveness.
