The Island Airport(Billy Bishop) in Toronto is littered with adverts that are camera connected. Other than, maybe power management, looking at what is possible in OpenCV gives a good indication of what can, and probable is, being done. From tracking where you look to matching faces.... The problem is that this is an agency(of the government) owned facility.
