Setup: Digital Noise Reduction (DNR)
Setup: Sens-up (Low Illumination)
The DNR technology increases S/N ratio for enhancing the image in
low illumination, raising DVR recording efficiency and storage
capacity.
1.
Position the arrow to DNR in setup menu by pressing
UP/DOWN button.
2.
Select the mode you wish to operate by pressing LEFT/Right
button.
OFF: DNR function is disabled
LOW: Suggested Level – The level has a basic control on
noise reduction with almost no ghost image.
MIDDLE: The level is applied when the noise is obvious. A
ghost image would appear in low illumination.
HIGH: Noise is greatly reduced while ghost images are
increasing.
NOTE: DNR works with AGC. When AGC is off, DNR will be disabled.
Sens-up helps maintain a bright, clear screen image by automatically
detecting changes of the level of light in low illumination.
1.
Position the arrow to SENS-UP in setup menu by pressing
UP/DOWN button.
2.
Select the mode you wish to operate by pressing LEFT/RIGHT
button.
OFF: SENS-UP is disabled
AUTO: SENS-UP will be on by auto light detection
NOTE: When selecting AUTO, press SETUP to enter into menu.
Adjust the mode from x2~x128. Return to last menu by pressing
SETUP while finishing modification. When AGC is off, SENS-UP will be
disabled. When SHUTTER is in MANUAL, FLK mode, SENS-UP will be
disabled.
NOTE: When selecting HIGH/MIDDLE/LOW, press LEFT/RIGHT to
adjust brightness in setup menu. Return to last menu by pressing
SETUP while finishing modification. When the AGC is on, the noise
will be caused by magnification on the signal of image brightness.
The noise depends on the level of AGC, so there will be more
noise when AGC is higher.
