Dahua Ceiling Mount Options

Does anyone know if you can add different lengths of rigid conduit to the Dahua Fish Eye Ceiling Mount? I need the camera to be at a very specific height.

From Dahua documentation I can't see how all of the parts go together. My other concern is that the screws thread that is used is European based so I don't know if NPT threads will screw in. The unit will be mounted inside so I'm not concerned about a weather tight seal, just sturdy.

Has anyone done this before?
