I have a Dahua IPC-T5442T-ZE that I installed a while back and now I need to slightly adjust the angle. The manual gives no clue about this other than to show a picture. Just guessing it was involved, I have loosened the small star screw in the center just under the top ring but nothing will move. How do I turn the turret and also tilt the lens up slightly?
From the manual:
thanks very much,
