I have my own special way of placing rotating trackside camera's.
the camera is dependent on the where abouts of the blinding, ol' yeller' compass.
I go zoomed in, and find a place for the blinding, ol' yeller' compass @ almost right on top the track, then pan up and down using the KB arrow keys, moving the camera a little at a time, until the FOV is all the way down low (like a pedestrian railfan's point of view), and is @ 10m-20m distant the track. Cameras always follow the center of a loco at the bottom of the fuel tank. I found that when placing a camera, by pressing the arrow keys @ 3 short bursts, away from the track, results in a uniform slightly more pleasant zoomed out view.
Very hard to describe, so I may post screenshots, or a video to better describe camera placement.
You can view a defective camera, and click on the "move camera" button ... and adjust it's right left up down angle position ... then press any above ruler buttons to "Set" the camera placement.
