Given the fact that the mount is a standard tripod thread, would it be possible to operate the camera upside down for using with telescopic ceiling mount?
Yes we plan to support this feature. We will invert the output of the camera.
How do you change it back so the video isn't upside down when you try to use a tripod again? We had it ceiling mounted and the camera was upside down. Now when you put it on a tripod the image is upside down.
