Abstract
Apparatus and methods for controlling access to a restricted area by an access control device includes obtaining a first image using a first sensor mounted at a first location. A second image is obtained using a second sensor mounted at a location different from a location of the first sensor. The second image is processed, using the second sensor, to obtain information regarding the detected objects in the second image. The information regarding the detected objects is sent from the second sensor to the first sensor. The first sensor compares the received information with a number of objects detected using the first image. A tailgating event is identified, in response to determining that the number of objects detected using the first image does not match the information regarding the number of objects detected using the second image. A tailgating notification is outputted, by the first sensor, indicating a tailgating event.
