define the iris value according to related content in this section if you choose IRIS mode.

SHUTTER: User-defined shutter speed, auto iris and auto gain. It is the shutter-priority mode.

Please define the shutter speed according to related content in this section if you choose

SHUTTER mode.

MANUAL: User-defined iris, gain and shutter. Please define the iris value, gain value and

shutter speed according to related content in this section if you choose MANUAL mode.

 Set the Iris Value

The IRIS value measures the amount of light entering to the lens. You can set the iris value from

0 to 17 in response to the changing light conditions.

Note: Iris is fully closed at value 0 and fully open at value 17.

 Set the Gain

 Gain value. The value of gain indicates the amplification degree of the original image

signal. You can set the value from 0 to 15.

 Gain limit. The higher gain value you set, the more noises will appear in the image. You

can set the maximum user configurable gain value from 0 to 15 to limit the gain range and

control the noises in the image. Gain limit function varies according to the different camera

models.

Note: You need to change the IRCUT FILTER as DAY or NIGHT mode, and set the AE MODE as

MANUAL before you adjust the gain value.

 Set the Shutter

Purpose:

The speed of the electronic shutter controls the amount of light entering to the lens in a unit of

time (a second). You can manually configure the shutter speed for the speed dome, and you can

also enable the slow shutter function for low lighting circumstances.

(1) Shutter speed. The larger you set the SHUTTER value (the faster the shutter speed is), the

fewer the amount of entering light per second is, and the darker the image is. You can set

the value as 1, 2, 4, 8, 15, 30, 50, 125, 180, 250, 500, 1000, 2000, 4000 or 10000.

Note: The value of X indicates that the shutter speed is 1/X second. If you set the SHUTTER

value bigger (shutter speed is faster), the amount of entering light per second is fewer, and

the image is darker.

(2) Slow shutter. Set SLOW SHUTTER as 0, 1, 2, 3, 4 or 5. The shutter speed can automatically

slow down to extend exposure time under low lighting circumstances to obtain clearer

image.

Task 7: Configure exposure compensation.

You can set the EXPOSURE COMP value from 0 to 14. The default value is 7. You can adjust this

value to increase the brightness of the image.

Task 8: Configure white balance.

You can set WHITE BALANCE mode as AUTO, INDOOR, OUTDOOR, SELFDEF (self-defined), ATW

(auto-tracking) and HAUTO (half-auto).
