They must've been asleep then haha they're in one of the buildings near the gate by the main road. Im quite sure; he showed me out the gate, locked it behind me and went back inside his fancy stone security house. On the way out I asked him how he found me and he said on the cameras. I was on the way in when he caught me unfortunately. If you got access quickly that's maybe why you had better luck than I! And yes it definitely is fairly well fortified or I'm missing something real obvious!
because there was access on my visit, doesnt mean there will be now as things change.
