1. A method for monitoring a door state using image analytics, said method comprising:
capturing, using an imaging sensor, an image that includes a view of a doorway having a frame and a door and having a pair of tracking strips associated with said doorway, one tracking strip of said pair being attached to the door, and the other tracking strip of the pair being fixed to the frame, each of said pair of tracking strips being of a length greater than a width;
detecting in the image, using a processor, at least one of the pair of tracking strips associated with the doorway;
determining, using the processor, a lengthwise vector of each detected tracking strip;
setting the door state to closed if only one of the pair of tracking strips is detected, or if both tracking strips of the pair are detected and their respective lengthwise vectors are substantially parallel; and
setting the door state to open if both tracking strips of the pair are detected and their respective lengthwise vectors are substantially non-parallel.
