There are signs that say Camera Monitoring of the sight but according to her, that is not true. They were put there to keep trespassers away, but in fact are not in use.
Whether the cameras are in use or not (or even there at all) should not be an issue. There was obviously a concern about tresspassing. This should be a reminder to all of us that permission should be obtained before entering any property or building, even those that are abandoned.
