IMAGE ADJUST
Use these settings to fine-tune your video by adjusting brightness, color levels, and noise reduction among other options.
3DNR
3DNR, which is short for 3-D Noise Reduction, compares a sequence of video images over a period of time and blends them to
reduce graininess. When enabled, there are individual settings for day (D) and night (N) video. Use these sliders to reduce the amount
of motion blur that can occur due to noise reduction.

Sharpness
There are two sliders allowing you to adjust the sharpness of the
video for day and night images.
Brightness
Adjust this using the slider.
Gamma
This differs from brightness by adjusting the luminance of the video
image by reducing “noise” while still keeping blacks black and
whites white. This can be adjusted from .45 (lightest) to 1(darkest),
or left at the User (automatic) setting.
Blue/Red Gains
You can individually adjust the blue and red channels using these
sliders.
Lens Shading
Shading refers to the tendency for the corners of an image to be
darker than the center. When shading correction is enabled, the
image will be electronically corrected to lighten the corners.

NTSC/PAL
These are two of the television video modes used globally. If you are using a VGA or HDMI screen to view your DVR you will not need
to change this setting. NTSC is used throughout North America and parts of South America, while PAL is used elsewhere in South
America, Europe (except for France), Oceania and parts of Africa and Asia.
RESET
This menu allows you to reset everything back to the factory settings. It also displays the firmware version of the camera.
