Select the day/night mode.

automatically. It will follow Day to Night and Night to Day
threshold defined by user below.
Day: The camera will stay in day (Color) mode.
Night: The camera will stay in night (black & white) mode.
Day/Night Type
Select the method used by Camera to determine illumination
level. It can be either CDS light sensor or through image analysis
by DSP. Not every model will allow selection for this.
Switch from Day
mode to Night mode
This value controls the level of light where camera switches from
Day mode into Night mode. Increasing it will make camera
switch to Night mode at a darker illumination level.
Switch if lasts more
than X seconds
The camera will only switch day/night status if the illumination
level stays either above or below the boundary for this much
time. This is to prevent a temporary brightness change from
triggering unnecessary day/night changes.
Switch from Night

Day mode. Increasing it will make camera switch to Day mode at
a darker illumination level.

Day/Night IR LED
IR LED may be configured as AUTO or Disabled here. If it is set
as AUTO, LED will turn on in night mode and turn off in day
mode. If set to Disabled, LED will stay off when camera switches
into night mode.
Brightness Meter Bar
This bar shows the illumination level at which cameras go to
night or day mode (Blue / Red bars), and shows the current
detected illumination level (Green bars). Use this bar to fine tune
the day/Night switch timing.
