WDR.

Auto - automatically switch between 2D and 3D. Use Sensitivity
option to adjust sensitive level. The higher level means the
higher sensitivity.
(3) IR-cut Filter The IR cut filter is a mechanism that prevents the infrared light
from hitting the sensor. During day time the IR light has an
interfering effect on the image quality of the camera, which leads
to corruption of color and contrast as well as blurring. At night
time, the infrared light is used to achieve more detailed images in
the dark or with low ambient light.
Auto – automatically switch on/off the IR cut filter. It uses the light
sensor in front of the camera to determine the level of ambient
light.
Day Mode – switch on the IR cut filter at all time to prevent the IR
light from hitting the sensor so that the color will not be corrupted.
Night Mode – switch off the IR cut filter at all time to let the sensor
receives the IR light which could help improve low light sensitivity.
Schedule – specify the time on when to switch off the IR cut filter
to night mode. The time format is hh:mm and in 24-hour clock
time.
(4) B/W image at night Select to enable/disable switching to B/W during night mode.
