Made some more progress today. Could not do quite as clean of a wire fish to this location with the nature of the truss and roof configuration but I did get pretty close to clean. I would have liked to gone a little lower on the soffit but that meant drilling through a truss and I did not want to do that. I also wanted to keep the camera as best protected from the elements and the sun so I decided mounting on a horizontal surface here to get lower was the wrong call. This camera has to see over the privacy fence too for the back yard too so some height was needed.
The short section of tube is actually 1/2 copper pipe with a male adapter which is just a bit smaller then what conduit fittings would be. I drilled a hole in that trim board just deep enough to be a socket for the tube and then drilled a lot smaller hole after that. Easy to fix with Bondo later on if needed. The fish was inserting a fish rod from the outside with twine on it and then snagging the twine from the inside with another fish rod.
This is on the south side of the house as sort of an overview back towards the street. I think I will also install a small piece of sheet metal along the facia board for a bit of a sun shade for the camera to cut down on how much the sun beats on it all day long esp in the winter.
