■ Exposure time

: The Exposure time allows tuning for more or less light to enter the lens. The

congurable 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 Exposuretime 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 specied.
