WDR 
This setting controls digital Wide Dynamic Range (WDR). The camera also supports multi-exposure 
WDR (True WDR), which is explained below. True WDR is set from the TV System drop-down list. 
Digital WDR improves the image quality of scenes which have very dark areas and light areas in 
different parts of the scene. This causes the camera to determine average exposure settings 
corresponding to the average brightness of the scene. This results in the dark areas being too dark 
and the light areas being oversaturated. The digital WDR implements post-processing enhancement 
in order to balance the contrast level received from the sensor, thus improving the image quality. 
Select On or Off. Click Set to confirm the setting. 
Inverse 
The inverse function flips the image 180°. Select On or Off. Click Set to save the setting. 
Auto Calibration 
Auto Calibration automatically calibrates the camera when a deviation of dome pivot is detected. 
The camera constantly aligns itself against vertical and horizontal checkpoints to maintain accurate 
operation. Select On or Off. Click Set to save the setting. 
2DNR 
The 2DNR Noise Reduction function analyzes pixel by pixel and frame by frame to eliminate 
environmental noise and deliver optimized image quality, especially in low-light conditions. Select 
On or Off. Click Set to confirm the setting. 
3DNR 
3DNR provides superior noise reduction and is recommended for use in in extra low-light conditions. 
It is especially useful for reducing blur with moving objects. Select On or Off. Click Set to confirm the 
setting. 
OSD 
Enable the OSD (On-Screen Display) function to display the camera tilt, angle, and zoom ratio 
settings in the Live View pane. Select On or Off. Click Set to save the setting. 
Set Pan Zero 
Set the current camera position as the Pan Zero (due north) point for the camera. Click Set to save 
the setting. 
TV System 
The camera supports multi-exposure WDR (True WDR), which is implemented by using a 
combination of slow- and fast-exposure shutters. The camera uses an algorithm to determine the 
optimal mix of regions within the scene from the two shutters in order to adjust the wide dynamic 
range of the scene. True WDR is recommended for most lighting conditions is enabled by default. 
From the drop-down list, select the video format that matches your TV system and the type of WDR 
you prefer: 
  WDR 30 fps (NTSC) – Enables the use of True WDR on an NTSC TV system 
  WDR 25 fps (PAL) – Enables the use of True WDR on a PAL TV system 
  Normal 30 fps (NTSC) – Enables the use of digital WDR on an NTSC TV system 
  Normal 25 fps (PAL) – Enables the use of digital WDR on a PAL TV system 
Click Set to confirm the setting.
