Automated tailgating detection via fusion of video and access control
First Claim
1. An automated tailgating detection system for an entry through a door or other entry port into an area of interest, comprising:
- an entry authorization sensor operable to detect a valid entry credential presented at said door, and transmit a signal indicative of the number of valid entry credentials detected;
a tailgate detection processor for receiving said signal indicative of the number of valid entry credentials detected;
a door contact sensor for determining the state of said door, and adapted to send a signal to said tailgate detection processor when said door is opened and/or closed.an automated video surveillance system, which captures images and includes image processing algorithms and perhaps fusion algorithms, for detecting persons proximate passing through said door and transmitting said images to said tailgate detection processor for determination of the number of persons entering through said door;
said tailgate detection processor being adapted to compare the credential number of valid entry credentials detected with the number of persons detected entering; and
an alarm mechanism for triggering an alarm when said credential number is less than said image number.

Abstract
An automated tailgating detection system for an entry through a door or other entry port, including an entry authorization sensor detecting valid entry credentials and transmitting the number of valid entry credentials detected. An automated video surveillance system detects, counts and tracks the persons who enter through the door. A tailgate detection processor receives the number of valid entry credentials detected and the number of people detected and sounds an alarm when the credentials number is less than the number of persons. A door contact sensor determines the state of the door, and sends a signal when the door is opened and closed.
