Thanks Dave, I just ordered two more cameras because I am going to try and mount one camera for every car spot and then have a rotary switch to set which camera is being used, that way I can have the cameras aimed better and the operator will just select the camera that is aimed at the car being loaded. I think I can have a better side view of each car rather than a "looking down the string of cars" view. I want to try and get each camera aimed at the same view so I can have a load fill line on the screen to make sure there is no over filling. I don't want the cameras to replace actually looking at the cars when they are loading, rather I want them to help someone new learn the correct fill level or help someone that maybe can't see the loading as well as needed.
