Detects two or more people passing through a secured door on a single credential (piggybacking), one of the most common access-control breaches, and alerts security in real time. Runs on any camera covering a door, turnstile, or mantrap with no extra hardware.
Visylix Tailgating Detection watches secured entrances for piggybacking, where a second person slips through a door, turnstile, or mantrap on someone else credential. It is one of the most common access-control breaches and is invisible to the badge system alone. Using any camera that already covers the entry point, the AI counts how many people pass through during a single access event and raises an alert in real time. Standalone, it does group-crossing detection from video alone and needs no other hardware. Opt in to badge-to-body correlation with a supported access-control system (HID, Lenel S2, AMAG, Brivo, Genea, and Bosch), and Visylix compares how many people crossed the door with how many badges were presented, alerting only when more people entered than credentials, the true tailgating signal. It understands the direction of travel so it only reacts to people actually entering, and lets you configure how many people and how much time count as a violation.
Core capabilities of the Tailgating Detection model.
Flags the moment a second person follows an authorized entrant through a secured door, so security can respond immediately.
Runs on any existing camera covering a door, turnstile, or mantrap with no extra hardware to install.
Understands the direction of travel and reacts only to people actually entering the secured side.
Set how many people and how much time count as a violation to match each entrance.
Integrate a supported access-control system (HID, Lenel S2, AMAG, Brivo, Genea, or Bosch) and Visylix correlates how many people crossed the door with how many badges were presented, alerting only when more people entered than credentials, the true tailgating signal.
Runs as group-crossing detection from video alone with no integration, or steps up to badge-to-body correlation when connected to your access-control system.
Raises an alert with a snapshot through dashboard, SMS, email, and webhook notifications.
Keeps a searchable, timestamped record of every piggybacking event for audits and investigations.
Adjust the people count and time window for each door so busy lobbies and high-security vaults each behave correctly.
Real-world applications for Tailgating Detection.
Protects drug rooms, wards, and restricted clinical areas from unauthorized entry.
Stops unauthorized entry at the front door of offices, labs, and secured buildings.
Protects server halls and cages where a single unauthorized entrant is a serious breach.
Enforces one-person-per-credential passage at turnstiles and mantraps.
Guards doors into cash rooms, evidence stores, and other restricted zones.

By default Visylix Tailgating Detection counts how many people pass through a secured door, turnstile, or mantrap during an access event, from any existing camera and from video alone, flagging group crossings in real time. It understands direction so it only reacts to people actually entering.
Yes, as an opt-in. Integrate a supported access-control system (HID, Lenel S2, AMAG, Brivo, Genea, or Bosch) and Visylix correlates how many people crossed the door with how many badges were presented, alerting only when more people entered than credentials, the true tailgating signal. Without an access-control system it still does group-crossing detection from video alone.
No. It runs on any camera that already covers the door, turnstile, or mantrap, with no extra hardware. Badge-to-body correlation is an optional enhancement that reuses your existing access-control integration.
