I'm not sure why you quoted that because there is a camera in operation and whether Amazon 'has a practical' purpose for it or not is irrelevant here.
Would be like finding a camera in a girls locker room and then saying 'we have no need for that'. Like what the hell is doing there is the real question and I suspect it does have a practical purpose for Amazon.
