Image quality

Allows you to adjust each video image to your requirements. All changes are displayed
immediately. Be aware that changes in the image quality affects processor performance.
Video
Enter the number of the camera you want to adjust. If you want to do this for each camera,
enter the number of the camera, adjust the settings (brightness, contrast, etc.), and then
enter the next camera number, and adjust their settings.
Brightness
Enter the value to adjust the brightness of the video image to your working environment.
Contrast
Enter the value to adjust the contrast of the video image to your working environment.
Saturation
Enter the value to adjust the color saturation of the video image on your monitor as realistic as
possible.
Low-pass filter
Enter the value to remove very fine noise from the image. This reduces and optimizes the
bandwidth necessary for the image transmission over the network. The image resolution may
be impaired. The higher the value, the flatter the image signal.
Default
Click to change the current settings to the factory settings.
Show Image
Click to display the image window of the encoder. In the menu bar of the video image you can
select the video input that you want to display.

video recorder.
Input 1-Input 4
Select VCR to connect video recorders as video source. Select Camera to connect cameras.
In some cases, selecting VCR also for cameras can lead to an improvement in the video image.
