Scroll to choose from the sub menu items listed below.
BRIGHTNESS [0 ~20]: This function is used to adjust the bright-
ness of the camera picture.
SHUTTER [1/30, 1/50, 1/60, 1/120, 1/240, 1/500, 1/1000,
1/2000, 1/4000, 1/8000, 1/16000, 1/30000, 1/60000]: You can
select one of 14 options from 1/25 to 1/60000K for the fi xed high
speed electronic shutter, which is mostly used for imaging a fast
moving object.
SENS-UP [OFF, AUTO, x2~x60]: Automatically detects the ambient
level of darkness in a dark or low contrast scene to extend the accu-
mulated time, keeping the image bright and sharp.
AGC (Automatic Gain Control) [0-20]: The AGC (Auto Gain Control)
function is used to amplify the video signal when it falls below the
set parameter. As the AGC level increases, the overall screen gets
brighter but the level of noise will also increase at the same time.
4.6 White Balance
This function allows the ability to adjust color temperature.
The camera needs to fi nd a reference color temperature, which is a
way of measuring the color of a light source, for calculating all the
other colors. The unit for measuring this ratio is in degree Kelvin(K).
You can select one of the White Balance Control modes according to
the installation condition.
AUTO: In this mode, white balance works within its color tempera-
ture range. This mode computes the white balance value output
using the color information from the entire screen. It outputs the
proper value using the color temperature radiating from a black
subject.
AUTOext: With the Auto Tracking White Balance function, the white
balance in a scene will be automatically adjusted while temperature
color is changing. The AUTOext Mode is suitable for environments
with a light source having a color temperature in the range roughly
from 1,800 ~ 10,500K (sodium lights to outdoor cloudy environ-
ment).
PRESET: This mode is set to the current white balance condition
and keeps its value. Select this mode and then press the SET key.
If there is a change in location or light source, please repeat this
procedure.
MANUAL: Can be used for fi ne adjustment. Set the White Balance
by fi rst using AUTO or AUTOext and then change to MANUAL and
press the SET key. Increase or decrease the value of R-Gain (Red)
and B-Gain (Blue) while monitoring the color of the image.
- KELVIN [MIDDLE / HIGH / LOW]:
- R-GAIN : Adjusts the White Balance for the color Red.
- B-GAIN : Adjusts the White Balance for the color Blue.
4.7 Backlight
When there is a strong backlight behind the object, clear images of
the background as well as the object can still be obtained by using
the BACKLIGHT function.
OFF: Not being used.
HLC (High Light Compensation): This function is used to suppress
or mask a strong light source (for example, headlights of cars
during nighttime) so that other subjects can be seen in more detail.
If you select HLC, a submenu appears where you can make fi ner
adjustments.
- HLC LEVEL: Adjust the brightness level from which on the
light source is to be masked out.
- MODE: All DAY & NIGHT ONLY Selectable.
BLC (Back Light Compensation): This function is used to counter
balance the screen image by increasing the brightness so that a
subject which appears dark due to a strong backlight can be dis-
played in more detail. If you select BLC, a submenu appears where
you can make fi ner adjustments.
- H-POS / V-POS / H-SIZE / V-SIZE: Defi ne the position
and size of the area of interest by changing the position
& size.
WDR: The WDR (Wide Dynamic Range) function works to correct
excessive light within the frame to produce a usable image. When
the image has simultaneous bright and dark areas, it makes both
areas distinct. If you select WDR, a submenu appears where you
can make fi ner adjustments.
WEIGHT [MIDDLE, HIGH, LOW]: Select the WDR level of the cam-
era.
Note:
• The WDR function might lead to a reduced framerate and
“ghost” effects in areas with very bright background.
• Please check effect of DWDR in section 4.11 if you need to
further optimize a WDR scene.
4.8 DNR
This function is used to improve the picture quality by fi ltering the
noise which is generated under low bright light conditions. You can
set different levels here.
- OFF / LOW / MIDDLE / HIGH selectable
