There have been many ideas on how to save s direction in the db, including:
  - a special "destination" node, connected to the cctv by a relation
  - an angle in the attributes (?)
  - destination coordinates in the attributes
  - a short piece of way, starting at the cctv and marking the "line of
    sight"

You may choose one.
