We developed a windows based video analyser that is able to count the number of patrons exiting or entering a business. It does this by using a video stream such as a security camera or a webcam. This has an added benefit over other systems as it was less sensitive to environmental change and didn't need to be mounted directly on a doorway.
Our system is able to be fine tuned for different distances and sensitivites to gain the maximum accuracy.
Rough Cost: $20,000
