Day/Night: These settings activate an IR cut filter that is in front of the sensor to
remove the IR during daytime operation for correct colorimetry.
Auto - The IR cut filter is automatically enabled - in during daytime and
out at night for maximum sensitivity.
On - The IR filter is always out of light path.
Off - The IR filter is always in the light path
Night Mode:
Color - The video picture is always in color.
BW - The video picture goes to black and white during low light for
maximum sensitivity.
BW with burst - The video picture goes to black and white during low
light for maximum sensitivity. A color burst is present for better stability on
a color monitor or recorder.
Gain Boost: These options let you specify additional gain when the camera is
night mode.
None: Will not provide any gain boost. Use this selection for normal video
output.
6db: When in night mode provides added gain. This will give your video
picture extra sensitivity, but can also bring up unwanted noise in your
video picture.
The Day/Night Threshold Setup settings are for initiating when the change over
from day to night and back again occurs.
Out - Determines when the light level is low enough to move the camera
out of night mode.
In - Determines when the light level is high enough to move the camera
into night mode.
Night time Parameters: These settings allow you to adjust the brightness and
grayscale quality of your video picture, and are active only when the camera is in
night mode.
Gamma - Use the slider to adjust the grayscale settings of a video
picture. For the most accurate picture, it’s best to adjust the gamma
setting at night.
Black Level - Under extreme low light it can be beneficial to raise the
black level of a picture. Use the slider to increase or decrease the
brightness of a picture during night operation.
Use the Reset Video button in the lower right-hand corner of the page to return all
