International arrivals in South Africa have the thermal camera - the line before they check your passport funnels you past the camera (whose screen is visible). If you come up "hot" then a separate immigration officer pulls you aside for a more in-depth questioning. These cameras first went up around the time the H1N1 swine flu was making headlines, and then just never came down. Since everyone is made to present their faces head-on, without glasses/masks, it would be trivial for the government to simply siphon off the data.
