It was weird, there were 4 different multi-turret cameras on the site, I walked into full view of 3 of them and walked around the central area just outside of the main metal spraying factory for around 10 / 15 mins taking pics of everything from different angles, completely in the open and in full view of the cameras, and for all I could tell they were powered off or blind! Absolutely no indication of anyone knowing I was there and this was broad daylight!
