9.4.4Day/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).
