Have been considering closed circuit video for monitoring multi train operation but I want to rule out this idea first.
I need to see around a corner. When at my main panel I am positioned 30 feet from the corner and the blind area to be viewed is 12' wide and 25' deep at a 90 degree angle.
Have been looking at parabolic mirrors. Practical? Size? Available 18", 30" and 36" diameter.
There is a old narrow PRR underpass in West Chester, PA that uses one at a dog leg roadway configuration and it got me thinking.
Anyone use one of these??
