IMPORTANT: Best focusing results can be achieved when the lens iris is fully open
(such as at night in low light). This prevents loss of sharpness if light levels are
reduced at night.
To achieve this during the day, in the Web Base Viewer go to the Camera 
Exposure screen and select from the Exposure Setting menu Auto-shutter
mode. Save changes and complete the focusing steps. When finished, restore your
exposure settings as needed.
5.) Adjust the zoom ring and focus ring for your scene.
6.) Replace the camera’s inner cover.
7.) Replace the mini-dome cover and screw.
