9.4.4 Day/night
The Day/Night camera is equipped with a motorized IR
(infrared) filter. The IR filter can be removed in low-light or IR-
illuminated applications. There are four different methods of
switching:
– via the alarm input,
– as part of the programmable mode profile,
– automatically, based on the observed light levels, or
– via the settings page.
Note:
For reliable Day/Night switching with an external IR illuminator,
synchronize the switching of the IR filter in the camera with the
IR illuminator using an alarm input port.
Day/night
Auto - the camera switches the IR cut-off filter on and off
depending on the scene illumination level.
Monochrome - the IR cut-off filter is removed, giving full IR
sensitivity.
Color - the camera always produces a color signal regardless of
light levels.
Switch level
Set the video Switch level at which the camera in Auto mode
switches to monochrome operation (-15 to 0 to +15).
A low (negative) value means that the camera switches to
monochrome at a lower light level. A high (positive) value
means that the camera switches to monochrome at a higher
light level.
Priority
In Auto switching mode, set the camera priority to either:
– Color: the camera gives color pictures as long as the light
level permits.
– Motion: the camera gives sharp images without motion
blur as long as the light level permits (it switches to
monochrome earlier than it would with Color priority).
