Tailgating Detection

Introduction In many high-security environments, such as corporate offices, data centers, and research facilities, access control systems are the first line of defense. However, even the most sophisticated card readers or biometric scanners have a fundamental weakness: tailgating. Tailgating occurs when an unauthorized individual follows an authorized person through a secure entrance before the door or gate closes. This common security breach often happens due to social etiquette—such as holding a door open for others—but it can lead to theft, corporate espionage, and safety risks. ACTi’s Tailgating Detection solution provides an intelligent, automated way to identify and prevent these unauthorized entries in real time, ensuring that access control policies are strictly enforced.

Common Challenges

Reliance on Social Norms: Employees often hold doors open for others as a matter of politeness, inadvertently bypassing security protocols and allowing unauthorized individuals into sensitive areas.

Limited Guard Presence: It is physically and financially impossible for security guards to monitor every secure entrance 24/7, especially in large facilities with multiple access points.

Incomplete Access Logs: Traditional access control systems only log the authorized user who scanned their badge. They cannot detect or record the presence of a second person who entered during the same door opening.

Difficulty in Confrontation: Security personnel or employees may feel uncomfortable confronting a tailgater, leading to "passive" security breaches that go unreported.

High Volume Foot Traffic: In busy environments like lobbies or transit hubs, manual observation cannot accurately distinguish between a group of authorized people and a stranger attempting to slip through.

ACTi Solution: AI-Powered Access Verification ACTi provides a proactive security solution that combines high-precision AI video analytics with access control integration to create a "double-check" system for every entry.

AI-Based People Counting: ACTi’s specialized AI cameras, often mounted in an overhead "bird's-eye" view, utilize advanced deep learning to count individuals crossing a virtual line with extreme accuracy. The system can distinguish between individuals even if they are walking closely together.

Access Control System Integration: The solution synchronizes with the facility’s existing access control software. When a badge is swiped, the system expects exactly one person to pass. If the camera detects two or more people entering for a single authorized swipe, it identifies a tailgating event.

Instant Alerts and Deterrence: Upon detecting a tailgating incident, the ACTi Video Management System (VMS) can trigger immediate actions. This includes popping up the live video feed for security operators, sending push notifications to management, or activating local alarms like strobe lights or IP-based speakers to alert the individuals involved.

Real-Time Visual Evidence: Every tailgating event is captured and bookmarked in the VMS. This provides irrefutable video evidence that shows both the authorized employee and the unauthorized person, making it easy to conduct follow-up investigations or safety training.

Automated Reporting and Compliance: Administrators can generate detailed reports on tailgating frequency across different locations or time shifts. This data helps identify "high-risk" doors and allows for data-driven decisions on where to increase security or staff education.

Scalable and Flexible Deployment: ACTi’s solution can be applied to various entry types, including standard swing doors, turnstiles, and sliding gates, making it suitable for both indoor corporate environments and outdoor restricted zones.

Conclusion ACTi’s Tailgating Detection solution transforms passive access points into intelligent, self-policing security assets. By automating the verification of every entry and providing real-time alerts for unauthorized follows, ACTi helps organizations close the "politeness gap" in their security and ensures that only authorized personnel have access to their most valuable assets.
