Is there a tool or a way to reset the alignment of the camera?
It makes a clicking noise like gears grinding when booting up
Unfortunately there is not a tool, outside of a simple reboot, to re-align the cameras.
Based on your description I would reach out to PTZOptics support just to have them help evaluate the current health of the camera.
