MODE: AUTO, OPEN, and CLOSE are selectable for iris mode.

Selecting auto means the iris is adjusted automatically; selecting

open means the iris is fully open; and selecting close mean the iris

is totally closed.

SPEED: Adjust the iris speed. The higher the value is, the faster

the speed of the auto iris is. The value ranges from 0 to 255.

Note:

It is recommended that you adjust the iris speed only when the iris

vibrates.

3.3 Shutter/AGC Setting

SHUTTER/AGC allows you to adjust the way the system balances

SHUTTER and AGC settings in different light conditions. You can

set the different shutter and AGC value according to the luminance

level of the situation.

You can choose MANUAL or AUTO mode for the shutter and AGC.

Note:

On the lens setting interface, if you choose lens type as AUTO, the

AUTO IRIS can also be adjusted to change the brightness of the

image; otherwise only shutter and AGC are adjustable.

In the AUTO SETUP submenu (Figure 3-2), you can adjust the

BRIGHTNESS value. The system will automatically adjust the

SHUTTER, AGC and AUTO IRIS settings according to the

BRIGHTNESS value. And the system can define and recognize the

luminance level automatically.
