The backlight compensation must be set depending on camera alignment, e.g. if the camera may 
point at the sun at some point during the day.
“OFF” 

Backlight compensation off

“BLC” 

Backlight compensation on

“HLC” 

 Backlight compensation and an additional masking function for too-bright 
image area are activated (too-bright image areas are automatically masked 
in „black“)

   

 

This 

setting 

falsifi es the image (too-light image areas are coloured black), but 

also permits easier observation of the objects right next to the bright image 
parts and even better recording of the image signals.

     

 It also protects older tube monitors or plasma screens from burning in of 
too-light image areas that are displayed for a long period (not required for 
screens with LCD technology).

This summarises all functions for setting the image:
“MIRROR” 

Horizontal image mirroring on/off

“BRIGHTNESS” brightness
“CONTRAST” contrast
“SHARPNESS” image 

sharpness

“HUE” Hue
“GAIN” Intensity

This function improves presentation of images with a strong contrast between dark and light im-
age areas.
If a camera is pointed, e.g., at a bright window from the inside, the image will show hardly any-
thing except for the bright window. 
If the function is activated (Setting “ON”), the camera increases both brightness and contrast in 
the dark areas.
The function is very important at night, so that, e.g., passing vehicles with bright lighting will not 
cause the area around them to become invisible.
