Hi all,
I want to share my experience in this case.
The issue here doesn't caused by the user or the camera themselfe.
Maybe it's one of few installations where the delivered mounting bracket of the camera is in use.
Cisco TAC pleased us to test function of the cam with dismounted bracket, which was possible instantly.
At next we mounted a washer between screw and camera - cam function was also ok.
My contact told me, that the main thing is the strength by affixing the screw.
In his point of view the mounting bracket in conjunction with the camera is a bad design.
A shorter screw would be a better fix, than a washer between bracket and camera.
So maybe it's a good hint for anyone who get in contact with a obvious mechanism (gearbox) defective of a Precision HD cam.
Regards,
Fabian
