setup
If <BACKLIGHT> is set to <BLC>, the MASK AREA function is not available.
EXT : The interface to an external alarm enables an automatic switch between DAY and NIGHT mode.
M If you use an infrared light source while in AUTO mode, this may cause a failure in AUTO SWITCH or AUTO FOCUS.
WHITE BAL
If you need to adjust the color according to the ambient illumination, you can use the <WHITE BAL> function.
Illumination is generally referred to as color temperature, which is represented in a measurement of kelvin (K). Color temperatures for ordinary lighting are as follows:
In the <WHITE BAL> menu, you can set a mode for correcting the <WHITE BAL>.
-ATW1,2 : If you set the <WHITE BAL> menu to <ATW1> or <ATW2> mode, this will monitor the change of the color temperature to correct the <WHITE BAL> as needed.
The following color temperature ranges are assured in individual modes:
ATW1 : 2500K ~ 9300K ( 1)
ATW2 : 2000K ~ 10000K
(suitable to sodium light source) ( 2)

1 : With <ATW1> mode active in a color temperature environment ranging beyond between 2500K and 9300K, a proper white balance value may not be produced; if this is the case, you are recommended to use <ATW2> mode.
2 : With <ATW2> mode active in a mostly single color environment, the display color and the actual one may differ; so select a mode as appropriate to your color temperature environment.
