Can set EXPOSURE MODE to AUTO, IRIS Priority, SHUT. Priority,
MANUAL and Flickerless.
AUTO – Optimizes the video level by controlling the iris and the
shutter speed automatically.
IRIS Priority – Selects to fix IRIS in a certain apperture and the video level
is controlled by an automatic shutter control.
Lower IRIS LEVEL will close more iris and increase the field of depth in
the daytime but significantly decrease the low light performance.
Too much low IRIS LEVEL will result in the foggy video by the diffusion
AUTO
from the lens iris.
SHUT. Priority - Selects to fix SHUTTER speed in a certain speed and the
video level is controlled by an automatic iris control.
This mode is useful when the color rolling occurs under the fluorescent
lighting. It is not recommendable at outdoor in the daytime.
MANUAL – Iris and Shutter can be set to fix.
Flickerless – Reduces the flicker in video when US(60Hz)/EU(50Hz)
mode is used in 50Hz/60Hz fluorescent lighting respectively.
SHUT. Priority, MANUAL and Flickerless modes disable SENS-UP and
MOTION BLUR functions.
10
Adjusts the brightness of video(0~20).
The brighter video can be obtained by increasing the exposure time in the
night with SENS-UP.
SENS-UP is the maximum integrations of frame by DSS(Digital Slow
Shutter) in the low light.
AUTO
AUTO – SENS-UP is enabled or disabled automatically by the scene
brightness. Higher SENS-UP can get the brighter video but the
slower frame rates with motion blur and more white pixels.
OFF – Disables SENS-UP.
AGC amplifies the video gain for brighter video but noise and white pixel
12
accordingly.
AGC level less than 10 disables AUTO in DAY/NIGHT.
ON enables MOTION DEBLUR to reduce the motion blur in a certain
ON
indoor enviroment. Noise or color rolling can increase.
