Image settings
The Image tab allows you to adjust image settings for each individual camera channel.
You may need to adjust the camera image depending on the location background in
order to get the best image quality.
You can modify the digital noise reduction (DNR) value to improve image quality. This
function removes image noise from a video signal, which can be more pronounced in
low light conditions.
Note : These options can also be modified from the image settings button on the live
view toolbar (see “Live view toolbar” on page 29).
To adjust display settings:
1. From the menu toolbar, click Camera Setup > Image .
2. Under Camera , select the desired camera.
3. Under Image Setting , only Custom is available.
4. Adjust the brightness, contrast, saturation and hue values by dragging each scroll
bar.
Click the Default button to return image setting values to the default position.
5. Select how you want the camera to rotate the image. There are two rotate functions:
Enable Rotate You can rotate the image 270°
In a vertical-shaped scene, such as a hallway or corridor, the image is
shown with a vertical (tall) rather than horizontal (wide) format. The
video image is at a 9:16 aspect ratio.
Mirror Mode You can flip the camera image three ways:
Left-Right: Flip the image horizontally.
Up-Down : Flip the image vertically.
Center : Flip both horizontally and vertically.
Note : This is only available for cameras that support the function.
6. Click Apply to save the settings and then click Exit to return to live view.

camera as well as create motion grids, set the sensitivity of the motion detection, and
link motion detection to a specific action.
To set up motion detection:
1. From the menu toolbar, click Camera Setup > Motion Detection .
Areas covered by the red grid are sensitive to motion detection.
