 Backlight Compensation (BLC)
If you focus on an object against strong backlight, the object will be too dark to be
seen clearly. The BLC (Backlight Compensation) function can compensate light to the
object in the front to make it clear, but this causes the over-exposure of the
background where the light is strong.
 Wide Dynamic Range (WDR)
The wide dynamic range (WDR) function helps the camera provide clear images even
under back light circumstances. When there are both very bright and very dark areas
simultaneously in the field of view, WDR balances the brightness level of the whole
image and provide clear images with details.
This feature varies depending on speed dome models.
 White Balance (WB)
White balance can remove the unrealistic color casts. White balance is the white
rendition function of the camera to adjust the color temperature according to the
environment automatically.
