Operation Manual

11.9. Camera - WB Mode

A camera needs to find a reference colour temperature, which is a way of measuring the quality of a light source,

for calculating all the other colours. The unit for measuring this ratio is in degree Kelvin (K). Users can select one

of the White Balance Control modes according to the operating environment. The following table shows the

colour temperature of some light sources for reference.

Light Sources :

Cloudy Sky (Colour Temperature: 6,000 to 8,000 K)

Noon Sun and Clear Sky (Colour Temperature: 6,500 K)

Household Lighting (Colour Temperature: 2,500 to 3,000 K)

75-watt Bulb (Colour Temperature: 2,820 K)

Candle Flame (Colour Temperature: 1,200 to 1,500 K)

Auto Mode :

In this mode, white balance works within its colour temperature range and calculates the best-fit white balance.

Indoor/Outdoor Mode :

Select Indoor or Outdoor.

ATW Mode (Auto Tracing White Balance) :

The Dome Camera takes out the signals in a screen in the range from 2000 K to 10000 K.

Manual Mode :

In this mode, users can change the White Balance value manually via specifying R-Gain and B-Gain; the range of

R/B-Gain is from 0 to 255.
