While most vendors today address tailgating by providing monitoring cameras and resulting alert notification, ZKTeco’s solution actually prevents tailgating from occurring in the first place. This AI-based solution not only authenticates the visitor wishing to pass through the turnstile (or door), but additionally recognizes the presence of more than one person using cameras.  If multiple people are detected attempting access, this overrides the turnstile’s locking mechanism, notifies security personnel, and prevents further access, even to authorized personnel.
