Parameters

Description

Day/Night mode

There are three modes:

Auto: The camera will automatically switch between day mode (color) and

night mode (black/white) under certain exposure level, defined by user at

“Switch from Day mode to Night mode”.

Day: The camera always stays in day mode (color) regardless of exposure

level.

Night: The camera always stays in night mode (black/white) regardless of

exposure level.

IR LED Control

This feature is visible only in cameras with built-in IR LED.

There are two modes:

Auto: The built-in IR LED will be turned on automatically upon day to night

switch and turned off upon night to day switch.

Disabled: The IR LED will be off regardless of day and night mode.

Zoom cameras have adaptive IR profile, which means that when IR LED

Control is set to “Auto” (default setting), the IR LED automatically adapts to

the required IR LED power as the camera is zoomed in or out.

IR LED Strength Level

This feature is visible only in fixed and vari-focal lens cameras with adaptive

IR profile and when IR LED Control is set to “Auto”.

The scale of 1~10 allows the user to manually define the power level of the

IR LED. The higher the value, the brighter the IR LED is. Set the IR LED

Strength Level according to the installation environment requirement, or

set it to “OFF” to turn off the IR LED.

Switch from Day mode

to Night mode

The scale of 0~100 allows user define the exposure level at which the day

to night switch should happen. The higher is the value, the darker the

environment has to be to trigger the day to night switch.
