Adjust the time threshold to set the minimum allowable time between successive object detections. Object tailgating is defined as an object crossing a line or zone within a certain time after an object has already crossed the line or zone. If an object crosses a line or zone, and another object crosses the same line or zone within the specified time window, the Object Tailgating filter will be triggered. In this example, Object 1 is about to cross a detection line. Another object (Object 2) is following closely behind. The tailgating detection threshold is set to 5 seconds. That is, any object crossing the line within 5s of an object having already crossed the line will trigger the Object Tailgating filter. Object 2 crosses the line within 5 seconds of Object 1. This triggers the Object Tailgating filter. 05-2018-A 30 | P a g e

Object Tailgating
Enable the object tailgating rule on the selected zone by checking the Object Tailgating box in the
properties inspector. Adjust the time threshold to set the minimum allowable time between successive
object detections.
Object tailgating is defined as an object crossing a line or zone within a certain time after an object has
already crossed the line or zone. If an object crosses a line or zone, and another object crosses the same
line or zone within the specified time window, the Object Tailgating filter will be triggered.
In this example, Object 1 is about to cross a detection line. Another object (Object 2) is following closely
behind. The tailgating detection threshold is set to 5 seconds. That is, any object crossing the line within
5s of an object having already crossed the line will trigger the Object Tailgating filter.
Object 2 crosses the line within 5 seconds of Object 1. This triggers the Object Tailgating filter.
