Anti-Tailgating
Physical and software measures that prevent an unauthorized person from entering a secure area by following closely behind an authorized person.
Solutions include physical turnstiles, door interlocks, camera-based person counting, and event-based alerts when multiple entries occur on a single biometric event.
Frequently Asked Questions about Anti-Tailgating
What is the difference between tailgating and piggybacking?
Tailgating is unauthorized — sneaking in behind someone. Piggybacking is when the authorized person knowingly holds the door. Both are addressed by turnstile integration and zone counting.
Can software alone prevent tailgating?
Software can detect and alert, but physical barriers — turnstiles, speed gates, mantrap doors — are needed to physically prevent it. Nialabs integrates both for complete coverage.
Does Nialabs support occupancy tracking to detect tailgating?
Yes. Nialabs can track zone occupancy using entry/exit counts — if the count shows more people inside than verified entries, a tailgating alert is raised automatically.
