4.2.3 White Balance
Select a white balance mode according to external light condition for the best color temperature.
Auto White Balance: Use this option when there is no special lighting in the environment. The
camera will automatically adjust the color temperature according to the light conditions and
the sensitivity you specify. The higher the sensitivity, the faster the adjustment. If the lighting
conditions change frequently, select a lower sensitivity to prevent the camera from frequently
changing white balance.
Manual White Balance: With any special light in the environment, you can use this option to
manually adjust the red, green and blue channels, which are mostly affected by the special light.
For example, if red color is too bright, then you should lower the R Gain value.
When nished, click Save to have the conguration take effect.
