Tailgating detection in frictionless access control system
First Claim
1. An access control system for monitoring an access point, comprising:
- a system controller;
a positioning unit for tracking locations of users carrying user devices relative to the access point based on wireless signals from the user devices, the positioning unit including antennas that receive packet data from the user devices of the users, the positioning unit communicating with the system controller; and
wherein the access control system determines whether the users are authorized to pass through the access point based on the wireless signals from the user devices and determines whether non-authorized users are tailgating through the access point; and
wherein in response to the access control system determining that all of the users are non-authorized, the access control system generates an alert in response to determining that the non-authorized users remain within a threshold area of the access point for longer than a predetermined lingering threshold value.

Abstract
A system and method for determining tailgating of users in a frictionless access control system are disclosed. The access control system includes a positioning unit that tracks locations of users carrying user devices relative to an access point of a premises, where the user devices transmit user information identifying the users via wireless signals. The access control system then determines whether the users are authorized to pass through the access point based on the wireless signals from the user devices and determines whether non-authorized users are tailgating through the access point with authorized users. In embodiments, the system can also determine tailgating of the users in response to analyzing video data of a scene including the users, where the video data is generated by a video camera positioned to capture the users when the users are within the threshold area.

12. An access control system for monitoring an access point, comprising:
-
a system controller; a positioning unit for tracking locations of users carrying user devices relative to the access point based on wireless signals from the user devices, the positioning unit including antennas that receive packet data from the user devices of the users, the positioning unit communicating with the system controller; at least one video camera that captures video data of a scene that includes a threshold area of the access point; and a video analysis system that analyzes the video data to determine a number of users within a threshold area of the access point, wherein the access control system determines that the users are tailgating by determining that a number of user devices detected within the threshold area by the positioning unit does not match the number of individuals within the threshold area determined by the video analysis system; wherein the access control system determines whether the users are authorized to pass through the access point based on the wireless signals from the user devices and determines whether non-authorized users are tailgating through the access point. - View Dependent Claims (13)

14. A method for controlling access of users to an access point, comprising:
-
tracking locations of users carrying user devices relative to the access point via a positioning unit associated with the access point, based on wireless signals sent from the user devices; determining whether the users are authorized to pass through the access point based on the wireless signals from the user devices and determining whether non-authorized users are tailgating through the access point; and generating an alert in response to determining that the non-authorized users remain within a threshold area of the access point for longer than a predetermined lingering threshold value. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A method for controlling access of users to an access point, comprising:
-
tracking locations of users carrying user devices relative to the access point via a positioning unit associated with the access point, based on wireless signals sent from the user devices; determining whether the users are authorized to pass through the access point based on the wireless signals from the user devices and determines whether non-authorized users are tailgating through the access point; at least one video camera capturing video data of a scene that includes a threshold area of the access point; analyzing the video data to determine a number of users within the threshold area of the access point; and determining that the users are tailgating by determining that a number of user devices detected within the threshold area does not match the number of individuals within the threshold area determined from analyzing the video data. - View Dependent Claims (23)
