I mean, he or she is collecting images with their eyes and storing them in their brain. We're fine with that because it's only local storage--the police can't just plug a network cord into your security guard and suck out all the images and timestamps every hour. I think facial recognition door systems are a fine idea if they can be implemented like a doorman: local storage only, carefully trained on local data. With current technology that would be impossible or extremely expensive, though.
