I think you are doing great! No problems at all!
I need to know if the PTZ commands are correct. So I would appreciate if you can do this:
-in NCS delete the camera DN-16055 using the Custom URL
-add the same camera, but use the template like this:
-When you click on Test connection you will get 2 red icons. That is fine.
-Click on Save.
-Now you will have a gray or white image telling you that there is no connection.
-I am not sure about this, but can you see the PTZ controls?
-If you can see them test them and see if the camera moves. If the camera moves you can stop here and report back.
-If you cannot see the the PTZ control, please add the camera in WebcamXP or 7 and test the PTZ controls and see if the camera moves.
By the way, interesting project with tracking the moving object. That is not in NCS, but it is a really good idea for the future!
