Set the Gain
1. Gain value. The value of gain indicates the amplification degree of the original image signal.
You can set the value from 0 to 15.
2. 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.
You need to change the
DAY/NIGHT
as
DAY
or
NIGHT
mode, and set the
EXP
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.
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
ON
, 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:

You can set
WB MODE
as
AUTO
,
INDOOR
