Configuration and Operation
CP-4221-301 Camera – Misc2 Screen
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
2DNR (2D Noise Reduction) analyzes individual frames pixel by pixel and frame by frame to eliminate
environmental noise and deliver optimized image quality, especially in low-light conditions. 2DNR tends to
produce superior results for moving objects when applied to areas in the field of view where movement is
present. However, it is less precise than 3DNR. Select On or Off. Click Set to confirm the setting.
