1. A method for discerning a vehicle at an access control point, the method comprising:
- obtaining a first video sequence of the access control point from a first camera operable to capture video of the vehicle approaching a first gate;
detecting an object of interest from the first video sequence;
tracking the object from the first video sequence to obtain tracked-object data;
classifying the object as a class of vehicle;
determining that the vehicle is present in a predetermined detection zone of the access control point based on the tracked-object data;
controlling activation of the first gate at the access control point based on at least the class of vehicle;
obtaining a second video sequence of the access control point from a second camera operable to capture video of the vehicle approaching a second gate;
detecting the object of interest from the second video sequence;
tracking the object from the second video sequence; and
controlling activation of the second gate is based on determining if the vehicle is being tailgated.
