A video based system and method for detecting and counting persons traversing at least two areas being monitored. The method includes the steps of initialization of at least one end unit, having at least a camera, the camera producing images of at least a first area being monitored and a second area being monitored, digitizing the images and storing the digitized images in a non-volatile memory unit and a working memory unit; detecting potential persons in the images; comparing the digitized images of objects detected in the first area and second area being monitored with digitized images stored in the working memory unit to determine whether the detected object is a new figure in such area or whether the detected object is a known figure that has remained within such area and to determine that a figure which was not detected has left such area; incrementing a counter for such area with an indication of the number of persons that have passed through such area, and comparing the number of persons passing through a first area with the number of persons passing through a second area.
