Threshold values
• You can set the threshold value that determines high
or low intensity.
• The minimum threshold value is 1h (decimal: 1), and
the maximum threshold value is FE1h (decimal:
4065).
• The default setting for the threshold value is 200h
(decimal: 512).

Temperature Reading Function
The conversion value (hex) of the temperature sensor
built into to the camera can be read by using a query
command. The conversion value has an error of ±3 C,
and because the temperature sensor is inside the
camera, this value is not the ambient temperature. Use
it as a reference value.
Slow shutter – Auto/Manual
When set to "Auto, " ensures that the slow shutter is set
automatically when the brightness drops. Effective only
when the AE mode is set to "Full Auto. "
Set to "Slow Shutter Manual" at shipment.
Note
The Slow Shutter Auto function is not available in WD mode.
Low-Illumination Chroma Suppress Mode
You can configure a chroma suppress mode for low-
illumination conditions. This can be useful when color
noise is particularly noticeable in such conditions.
Four levels (disabled and three levels) are available for
the low-illumination chroma suppress mode. Set the
effect to be applied at approximately 15 dB. Higher
setting values produce stronger chroma suppressing
effects.
ICR (IR Cut-Removable) Mode
An infrared (IR) Cut-Filter can be disengaged from the
image path for increased sensitivity in low light
environments. The ICR will automatically engage
depending on the ambient light, allowing the camera to
be effective in day/night environments.
When the auto ICR mode is set to ON, the image
becomes black and white.
Custom Color Gain
You can customize and configure the color gain. Use
this setting when bright color is particularly important.
The initial setting 100% (4h) can be set to range from
approx. 60% (Oh) to 200% (Eh) with 15 stages.

Custom Color Phase
You can customize and configure the color phase.
The initial setting 0 degrees (7h) is adjustable between
approx.
15 increments.
Auto ICR Mode
Auto ICR Mode automatically switches the settings
needed for attaching or removing the IR Cut Filter.
With a set level of darkness, the IR Cut Filter is
automatically disabled (ICR ON), and the infrared
sensitivity is increased. With a set level of brightness,
the IR Cut Filter is automatically enabled (ICR OFF).
Also, on systems equipped with an IR light, the internal
data of the camera is used to make the proper decisions
to avoid malfunctions.
Auto ICR Mode operates with the AE Full Auto setting.
