White balance
White balance (WB) tells the dome camera what the color white looks like. Based on
this information, the dome camera will then continue to display all colors correctly
even when the color temperature of the scene changes such as from daylight to
fluorescent lighting, for example.
The unit for measuring this ratio is in degree Kelvin (K). You can select one of the
White Balance control modes according to the installation condition. The following
table shows the color temperature of some light sources.
