IR Function
The IR Function setting activates two functions. It activates the IR LED illuminator for use in low-light
conditions or at night and activates
IR mode
, which is the IR Cut (IRC) filter for electronic day/night
operation.

IR Mode
The day/night IRC switching mechanism operates according to the ambient light level rather than
activation of the IR LED mode. The
IR Mode
drop-down menu enables you to select from
Auto/On/Off/Smart
modes. The default mode is
Smart
. Following is an explanation of the four
settings:
Auto Mode
– The camera converts from Day mode (color) to Night mode (monochrome)
automatically at nighttime or in low light conditions. When there is sufficient light, the
camera converts automatically from Night mode to Day mode.
On
– Activates IR mode (puts camera into monochrome/Night mode).
Off
– Deactivates IR mode (puts camera into color/Day mode).
Smart
– Smart mode enhances monochrome/Night mode stability when IR illumination is
dominant and keeps the camera from switching between Day and Night modes. In this
mode, the IR Cut filter is on (i.e. monochrome/Night mode) when the IR LED illuminator also
is activated. This prevents the camera from returning to color/Day mode.
