text: I went hunting for some photos to verify these 'cctv' notes. We can see this particular camera on this photo I think: https://commons.wikimedia.org/wiki/File:Path_leading_to_Royal_Holloway_University%27s_main_building.jpg   Now this shows the camera pole is on the north side of the footpath.
  
  We might conclude that these notes have not been placed super-accurately (although it might only be a metre off. They might be from accurate GPS readings) Key question is... are they accurate enough just convert into man_made=surveillance nodes? Elsewhere we'd want to be sure we're attaching the node to the right bit of the building. So not quite reliably accurate enough to just blindly convert. I'm afraid all these 'cctv' notes are...  needs survey
