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.
To adjust display settings:
1. From the menu toolbar, click Camera Setup > Image.
2. Under Camera, select the desired camera.
3. Adjust the brightness, contrast, and saturation values by dragging each scroll bar.
Click the Default button to return image setting values to the default position.
4. 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.
Default is OFF.
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.
Default is OFF.
Note: This is only available for cameras that support the function.
5. Click Save to save the settings.
V-stream encoding
The V-stream shows all camera channels within one camera tile. V-stream is available for
remote use with the browser interface, mobile application, TruVision Navigator or third party
software implementation.
This feature is particularly useful if you have limited bandwidth available on a remote location
but still want to be able to view all camera tiles at once.
V-stream encoding can be set for up to 16 cameras.
