• Use case: Typically for use in scenes with motion, e.g. overlooking
traffic.. Caution: The illumination required for this configuration would
need to be quite consistent.

• Set Max Bitrate to 8000
• Set any Iris position
• Set Max exposure and Min exposure allowed
• Set max gain value allowed
• Auto Exposure selects shutter speed (between min and max exposure
values) and gain (between 0db and max gain selection) to adjust expos-

• Use case: To select a required depth of focus. Selecting a high iris
valus gives a larger depth of focus so that objects close to and far from
the camera can be in focus at the same time. Caution: With a high iris
value the camera is not able to produce a bright image in very low light
levels
