■ Exposure time
: The Exposure time allows tuning for more or less light to enter the lens. The
congurable value ranges from 1/32000 to 1/5 of a second. An optimum shutter speed should be
maintained as long as the light level of the scene permits.
■
Gain control: Tune the slider bar to set the Gain Control to the best image quality. Higher gain
control value will generate a certain amount of noise, and that the gain control, lighting levels,
and picture performance are closely related.
Note that you can split the round pointers on the Exposuretime and Gain control slide bars
into two halves and drag them on the bars to designate a range of values in which rmware can
automatically adapt to. Firmware will then automatically tune the Gain, Exposure time, and Iris
opening within the ranges you specied.
