FUNCTION
Select this item and click on the select button to
open up a sub-menu that allows controlling
several aspects of the network camera, e.g.,
backlight compensation, day/night control,
brightness controls, privacy masking and motion
detection.
“BLC”: Backlight compensation
If the picture contains an area where there is a lot of
light in one location, e.g., a window, then a camera
tends to underexpose the entire image slightly. The
resulting image is then often too dark. With backlight
compensation activated, the camera overcomes this
problem by raising the exposure level slightly.
Set BLC to on using the right-arrow, then click the
select button to open up the sub-menu.
Click on BLC AREA to open the area setting, choose
the area where you want to set BLC manually and
press select to confirm the area (Once select is
pressed, the color of the selected area will change).
Repeat this step to activate the other areas. After
finishing setting the area, press the select button for
5 seconds to exit the menu. The next page allows
activating or deactivating all grid fields (all clear, all
set).
The BLC RATION controls, how strong the effects of
the backlight compensation should be.
“AGC”: Automatic Gain Control is a method to
improve visibility in low-light conditions. When AGC
is activated, the camera electronically enhances the
video, once the light quality drops below a certain
level. The advantage of this technique is that your
camera will produce images in much lower light
conditions than standard. The downside of AGC is
that it generates additional noise in the image.
Activate AGC by setting it to “on”. Click the select
button to open up the AGC control page. Use the arrow-right and arrow-down key to alter the
AGC gain value. Higher values make the video brighter, but the level of noise will increase.
If you operate the camera in normal daylight conditions, you do not need to activate AGC.
“DAY NIGHT”
The network camera can switch to black and white
video under low-light conditions to improve the
visible video.
“AUTO”: If the automatic mode is enabled, the
camera will engage the black and white mode based
on the parameters specified.
“B/W”: The black and white mode is permanently active, even during daytime conditions.
“COLOR”: The camera does not engage the b/w mode, regardless of the light conditions.
