How to make a static camera?

I don't fully understand your question.

If you don't want the camera to move, use Free Camera, and just leave it there.

If you are asking how to make the camera stay in place when using the pathCamera, try to simply add two markers with the same position. The camera will not move when it's going through those two markers.

 

You need a direct cut between two markers?
That's not a feature right now, but you can trick that by following the indications in my previous post.
If you add two or more markers in the same position, the camera will not move when going through them, as it's already where it should be.
