Wide Dynamic Range
Wide Dynamic Range (WDR) is a feature that supports the viewing of high contrast scenes that
include both bright and low light areas in the same field of view (FOV).
WDR Level allows you to adjust the WDR level to favor a underexposed or overexposed image. By
selecting the lower end of the control, the image is underexposed which provides more detail in areas
of bright but less details in areas of darkness. Selecting the higher end of the control, the image is
overexposed which provides more detail in the dark areas but less details in the bright areas.
A typical use for this feature would be viewing a scene with both indoor and outdoor lighting
conditions simultaneously, for example, in a warehouse area with an open bay door.
Procedure 66 Disable/Enable Wide Dynamic Range (WDR)

3 Select the required WDR from the drop-down list:
• WDR: Digital wide dynamic range, enhancing detail in darker areas
• True WDR: Two shutter wide dynamic range, to compensate for bright
and dark areas in the scene.
• True WDR3x: Three shutter wide dynamic range, to compensate for
bright and dark areas in the scene.
Note:TrueWDR3x does not apply to 8MP models.
Note:WDR and TrueWDR3x does not apply to the 2MP PTZ model.
The default setting is OFF.

Day Night Mode
IR/DayNight Mode utilizes a series of specific camera functions to dramatically enhance low light
performance.
When needed, the True TDN mechanism removes an IR Cut Filter (IRCF) from in front of the images
allowing the camera to see in black and white (BW) and utilize additional near-infrared energy found in
many lighting sources like halogen, moonlight, etc.
This, along with slowing down another function, the shutter speed, significantly improves low light
performance rendering clear images where none could be viewed previously.
IR Illuminator
When the camera is in B/W mode it can utilize or see near-IR illumination; something the human eye
cannot do. This can be extremely powerful when the dome is paired with 850~950nm IR illuminators.
