ELI5: How can companies get away with "By doing XXX you give permission for us to YYY" signs? Isn't that not how permission works?

If the sign was there before you agreed to be in the building, then they're in the clear.  It was a condition of going into the building.  If, however, they added that later, then you might have a case.  Being filmed was not part of the agreement that you made when you agreed to live there.
