Is the state of the art facial recognition technology deployed in real world, scenarios, though? It's one thing to use it in a lab setting with a person sitting still the perfect distance away from the camera, and quite another to operate on hundreds of people at once from a distant ceiling. Not to mention cost (i.e. the landlords don't actually care about accuracy that much, would they really pay a premium?)
