What Is Tailgating and Why Is It Dangerous?
Tailgating is when an unauthorised person follows an authorised employee through a secured door without presenting their own credential. It is the most common way intruders gain access to Dubai offices, server rooms, and restricted areas.
A single tailgating incident can result in data theft, equipment theft, or physical harm — all bypassing your expensive digital security.
Method 1: Anti-Passback Rules
What it does: The access control system tracks each card/biometric entry and exit. If your card was used to enter but not exit, it cannot be used to enter again — meaning the physical person cannot just hold the door for someone.
Best for: Main building entries, server rooms, any area where card-only access is used.
Cost: Software-only feature on most modern access control systems. No additional hardware required if your system supports it. Zero extra cost.
Setup: Enable anti-passback in your access control software (ZKTeco, Hikvision, Suprema, etc.). Define in-out readers at each secured door.
Method 2: Video Analytics with Tailgating Detection
What it does: AI-powered camera analytics detect when two people pass through a door opening on a single credential swipe. Triggers an alert to security management.
Best for: High-security entries, financial areas, data centres.
How it works: A camera above the door analyses the door-opening event. If the frame count detects more than one person per credential event, an alert fires.
Cost: AED 1,500 to 3,500 per camera point with analytics-capable camera. Requires an analytics-capable NVR or VMS platform.
Method 3: Security Mantrap / Airlock
What it does: A small enclosed vestibule with two doors. The first door must close and lock before the second door can open. One person in, one person out — no tailgating possible.
Best for: Server rooms, bank vaults, high-security data centres.
Cost: AED 25,000 to 80,000 for a proper mantrap installation depending on size and materials.
Method 4: Turnstile (Waist or Full Height)
What it does: Mechanical barrier that allows exactly one person per credential swipe. Physically impossible to tailgate a turnstile without triggering an alarm.
Best for: Building lobbies, warehouse personnel gates, visitor management areas.
Cost: Waist-height flap turnstile: AED 8,000 to 20,000. Full-height cage turnstile: AED 15,000 to 35,000.
