NETWORK PTZ CAMERA

User Guide

This feature is achieved by our innovative SV-IV DSP chipset. Unlike other cameras, this 

SNP-3750/3350 enables you to see clearly both an object and the background, even when 

the object is in extreme backlight .

 Back Light Mode : 

  - Off : Disables the Backlight mode. 

  - WDR : Use the WDR (Wide Dynamic Range) mode.

 

• WDR Setting : Three WDR sensitivity levels are available: Low, Medium, and

High. Note that the higher the sensitivity level, the lower the 

contrast in the light and dark areas becomes. 

 

• WDR Level : Adjusts the overall brightness of the screen in WDR mode.

 - USER : Select an area for which to use the Backlight feature. 

• WINDOW ON : Select to use the Area Selection window.

• DIRECTION : ALL – Moves the Area Selection window in a desired direction.

Detail – Adjusts the shape of the Area Selection window.

■Back Light

• WDR is disabled if the shutter is in Manual mode.
• During WDR operation, noise, discoloration, spots, and snow may occur depending on lighting  
  conditions. If they occur, stop using WDR. 
•

 

When selecting WDR, AGC Manual is disabled.

Caution

 - HLC :   Activates the Highlight Compensation mode.  

The HLC settings selectively eliminate highlights in a restricted environment such as 

the entrance to an apartment parking lot or gas station, and is useful to detect small 

objects like car license plates. HLC is disabled during the daytime. While monitoring 

nighttime car traffic, if car headlamps reflect too brightly on the screen, the camera 

automatically eliminates the headlamp lights and adjusts the colors of the license 

plate accordingly.

HLC Masking Area

<HLC ON>

<HLC OFF>

• Adjusts the HLC sensitivity level.

• Color : Adjusts the mask color on the highlighted area.

• Even if HLC is on, car license plates may not be detectable depending on the location and  

angle of the camera as well as the lighting conditions.
