Smart Supplement Light
This feature uses smart image processing technology to reduce overexposure caused by
supplement light.
Supplememt Light Mode
When the mode is set to Auto, the supplement light is
automacally turned on or o
according to the image brightness.
When the mode is set to Scheduled, set the start me and end me for the light to work.
When the mode is set to NC, the light is o.
Brightness Limit
Adjust the upper limit of supplement light power. For devices with both white light and IR
light, white light and IR light brightness limit can be set separately.
BLC
If you focus on an object against strong backlight, the object will be too dark to be seen clearly. BLC
(backlight compensaon) compensates light to the object in the front to make it clear. If BLC mode
is set as Custom, you can draw a red rectangle on the live view image as the BLC area.
HLC
When the bright area of the image is over-exposed and the dark area is under-exposed, the HLC
(High Light Compression)
funcon can be enabled to weaken the bright area and brighten the dark
area, so as to achieve the light balance of the overall picture.
WDR
The WDR (Wide Dynamic Range) funcon helps the camera provide clear images in environment
with strong illuminaon dierences.
When there are both very bright and very dark areas simultaneously in the eld of view, you can
enable the WDR funcon and set the level. WDR automacally balances the brightness level of the
whole image and provides clear images with more details.
Note
When WDR is enabled, some other funcons may be not supported. Refer to the actual interface
for details.
