Pelco Manual C1917M (12/97) 11
4.1 ADJUSTMENTS
Turn on the camera power and make the following adjustments.
4.1.1 White Balance
After fitting the lens and making all the installation connections, use a monitor to
check the picture and set the white balance as described below (refer to Figure 9).
AWB (Automatic White Balance) mode:
This mode is appropriate when lighting conditions are more or less constant. Point
the camera at a white object, such as a white wall or piece of white paper, so that
the monitor screen is as far as possible all white, then press the LOCK button. This
will calculate the current white balance setting and store it indefinitely in memory.
Thus there is no need to readjust the white balance after the power is turned off and
on again.
ATW (Automatic Tracing White Balance) mode:
In this mode the camera continuously adjusts the white balance according to the
changing lighting conditions.
