IR Function
Day/Night Function
This item serves to define the modes for the IR cut filter and IR LED lights.
Auto Mode
In this mode, the camera will determine the occasion to remove the IR cut filter.
Night Mode
Select this mode when the environment light level is low. The IR cut filter will be removed to enable the camera
to deliver clear images in black and white.
Day Mode
Select this mode to turn on the IR cut filter. The IR cut filter can filter out the IR light and enables the camera to
deliver high quality images in color.
Light Sensor Mode
IR LED lights will be turned on/off depending on the light sensor.
Light On Mode
In this mode, IR LED lights will always be on.
Light Off Mode
In this mode, IR LED lights will always be off.
Smart Mode
In Smart mode, the camera will determine the occasion to remove the IR cut filter. The Smart mode mechanism
can judge whether the main light source is from IR illumination. If the main light source is from IR illumination,
the IR cut filter will be kept open (i.e. monochrome/night mode).
Day/Night Threshold
This item enables you to define when the camera should switch from day mode to night mode or vice versa. The
camera will sense the surrounding brightness, and the threshold value represents the light level. If the camera
detects that the light level has reached the threshold, it will automatically switch to Day/Night Mode. The level range
is from 0 to 10 (darker = 0; brighter = 10).
Night Mode to Day Mode
The lower the value, the earlier the camera switches to Day mode. The default value is 7.
Day Mode to Night Mode
The higher the value, the earlier the camera switches to Night mode. The default value is 3.
Note:
This function is only available if the camera is in Auto Mode.
IR Light Compensation
With the IR Light Compensation function, the camera can prevent the center object close to the camera from being
too bright when IR LED lights are turned on.
