SmartCatch™  Human Tailgating

SmartCatch is an accurate and effective solution for detecting suspicious human tailgating at access control
areas. Using existing CCTV infrastructure, SmartCatch software monitors, identifies and tracks objects for security policy violations and enables quick response through real-time alerts and instant video replays. At the core of SmartCatch is a set of advanced video algorithms capable of performing complex behavioral analysis, tracking numerous objects and simultaneously identifying security threats in even the most complex environments. Human Tailgating is one of many available SmartCatch behaviors.
DEFINITION
The human tailgating algorithm detects humans from a CCTV camera and tracks their movement
through a door. Tailgating is detected by SmartCatch when two or more humans move
through a door within the camera view without the door fully closing between their entries.
Human tracking includes any type of human movement such as running or walking within a camera view range. SmartCatch tracks each human individually in order to detect tailgating, even if multiple humans pass through the access door at the same time.

   Tailgating Tip
Some users of the human tailgating behavior may allow multiple people to enter an access door at the same time
provided that each person scans their access card or other device to validate their entry. SmartCatch can
access this information to eliminate false-positive alarms when integrated with the access control system.
