Auto
The camera detects a colour temperature range and calculates an optimal white balance. The
Auto White Balance mode is suitable for light sources with colour temperature ranges from
2700 to 7500 K.
Indoor/Outdoor
The white balance is adjusted to a colour temperature range for either indoor or outdoor
lighting conditions.
ATW
In Auto Tracking White Balance (ATW) mode, the camera continuously adjusts the colour
balance to changes in the colour temperature which may occur, for example, when moving
from an indoor scene to an outdoor scene. The ATW mode is suitable for environments with
light sources ranging from 2500 K to 10000 K.
One Push
With the One Push function, white balance is adjusted and fixed according to the scene the
camera sees at the moment. This function is best for situations with minimal scene changes
and continuous lighting. The function is suitable for light sources with any kind of colour
temperature.
To set the white balance using One Push
1
Point the camera at the area to be monitored.
2
Under White balance, click One Push.
3
Click Set.
4
Click Trigger to adjust the white balance.
Note: In this mode, the value of white balance will not change as the scene or the light
source varies. Therefore, users may have to re-adjust the white balance by pushing the
Trigger button again when needed.
Manual
In this mode, users can change the white balance value manually by adjusting the Rgain and
Bgain. Rgain/Bgain values range from 0 to 255.
