Physical security is still at risk from unauthorized entry. Companies use access cards, biometric scanners, and guards to protect their physical spaces, but there are still many breaches in physical security. All of these systems provide credential authentication; however, they do not take into account how people act who people are when they gain access to a building. Tailgating detection involves detecting someone trying to gain access to a building by following behind another person who is authorized to enter. Tailgating detection uses the behaviour/intent of movement, not credentials, to measure the distance between objects. As threats emerge, organizations (primarily in the last year) see tailgating detection as a viable core layer of access control.
This article will review how advanced systems operate, supporting technologies, and AI-based platforms like VideoraIQ provide enhanced access control strategies.

What Is Tailgating Detection?
Tailgating detection is a security mechanism that identifies when unauthorized individuals follow authorized personnel through secured entry points. Unlike traditional access control systems that only verify credentials, tailgating detection monitors behavior and movement to ensure only authorized access occurs.
Key Features and Functions of Tailgating Detection
- Monitors Movement Patterns
The system tracks how people approach and pass through entry points. Abnormal movement patterns trigger alerts, preventing unauthorized access effectively. - Detects Multiple Individuals Entering Together
Tailgating detection identifies when more than one person enters on a single authorization. This reduces insider threats and prevents breaches. - Uses Spacing and Timing Analysis
By measuring the distance and time between people at doors, sensors detect suspicious behavior. This ensures only authorized individuals enter each secured area. - Integrates With Access Control Systems
The mechanism works alongside card readers, turnstiles, and biometric scanners, adding a behavioral verification layer to traditional security measures. - Real-Time Alerts for Security Teams
Alerts are generated instantly when tailgating occurs, enabling immediate response and preventing potential security incidents.
The Growing Risk Of Unauthorized Entry In Secured Facilities
Modern workplaces host a diverse range of employees, visitors, vendors, and contractors every day. High traffic increases convenience but also creates an opportunity for misuse. A single moment of courtesy holding a door open often leads to serious security exposure.
Unauthorized access causes data theft, asset loss, compliance violations, and personal safety risks. Traditional systems fail to address this challenge because they focus only on authentication. Once a door unlocks, no mechanism exists to ensure only one person enters.
Security teams need visibility beyond access credentials. Behavioral monitoring fills that gap and reduces reliance on human judgment.
Understanding Tailgating Detection In Access Control Environments
Tailgating detection refers to the process of identifying multiple individuals entering a secured area after a single authorization. The system recognizes abnormal entry behavior and alerts security teams in real time.
This approach works alongside existing access control tools. Card readers confirm identity, while cameras and analytics observe movement. Together, they create a complete security framework.
Organizations use tailgating detection across offices, campuses, hospitals, data centers, factories, and warehouses. The method improves awareness without disrupting daily operations.
Core Components Of An Advanced Tailgating Detection System
Every reliable tailgating detection system combines hardware, analytics, and alerting mechanisms. Cameras capture visual data, while AI models analyze movement patterns at entry points.
Advanced systems count individuals, track spacing, and monitor door usage. When the number of people exceeds authorization limits, the system triggers alerts. Security teams then respond immediately.
A tailgating detection system also stores event records. These logs support audits, investigations, and compliance reporting. Over time, analytics help teams refine security policies based on real behavior patterns.
The Role Of Tailgate Detection Camera Sensors In Entry Monitoring
Visual intelligence begins with accurate sensing. Tailgate detection camera sensors play a critical role in identifying movement near doors and gates. These sensors monitor depth, direction, and timing with precision.
Unlike basic motion detection, these sensors understand context. They distinguish normal foot traffic from suspicious following behavior. This capability reduces false alerts and increases trust in the system.
Tailgate detection camera sensors work effectively in both low-traffic and high-traffic environments. Lighting changes, crowd density, and entry speed do not compromise accuracy when AI models handle interpretation.
Why A Tailgating Detection Camera Matters At High-Risk Entry Points?
A tailgating detection camera is a critical component of modern access control systems. Its role goes beyond recording footage; it actively prevents unauthorized entry and enhances the efficiency of security teams.
1. Provides a Visual Foundation for Behavior Analysis
Tailgating detection cameras capture precise visual data, which AI analytics use to identify entry patterns. By observing movement, spacing, and timing, the system detects when someone follows an authorized individual into a restricted area.
2. Ensures Strategic Coverage of Entry Points
Proper camera placement near doors, turnstiles, gates, and restricted zones ensures no blind spots. This allows organizations to monitor high-risk entry points where unauthorized access is most likely to occur.
3. Enables Real-Time Threat Detection and Alerts
Advanced cameras deliver high-resolution footage analyzed instantly by AI. When suspicious behavior is detected, security teams receive immediate alerts, allowing rapid response to potential breaches.
4. Provides Evidence for Accountability and Audits
Recorded incidents include both visual evidence and metadata such as time, location, and entry method. This supports investigations, compliance audits, and organizational reporting.
5. Acts as a Deterrent Against Misconduct
The visible presence of cameras discourages employees, visitors, or intruders from attempting unauthorized access. Awareness of monitoring increases compliance and reinforces security culture.
Investing in tailgating detection cameras ensures accurate monitoring, deters unauthorized access, provides actionable evidence, and strengthens overall security at high-risk entry points.

Vehicle Tailgating Detection For Gates, Parking Areas, And Perimeters
Access risks extend beyond pedestrian doors. Vehicle entry points face similar threats, especially at industrial sites and logistics hubs. Vehicle tailgating detection identifies when one vehicle follows another through a secured gate without authorization.
This system tracks vehicle spacing, speed, and gate timing. When two vehicles pass on a single credential, the system flags the event instantly.
Vehicle tailgating detection protects assets, inventory, and personnel. Facilities that manage deliveries, fleets, or restricted parking benefit significantly from this capability.
