Wide Dynamic Range
Wide Dynamic Range (WDR) is a feature that allows 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 favour 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 3-13 Disable/Enable Wide Dynamic Range (WDR)

The video pane will update to display the new settings.
The values range from 1-10.
The default value is 5.
Day Night Mode
IR/DayNight Mode utilizes a series of specific camera functions to dramatically enhance low light performance.
When needed one of these functions, the True TDN mechanism, removes an IR Cut Filter (IRCF) from in front of
the imager 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. With this combination a
scene can be well lit with IR light that the dome can see but people cannot. This is great for areas where externally
lighting is not allowed or there is a need for covert security.
