Image settings

Image appearance

Modify image appearance to optimize the video images according to your requirements.

All configuration of images and overlays will affect the performance of the video server, depending on the usage and the available bandwidth.

•High resolution generates larger files

•Lower compression improves image quality, but generates larger files

•Rotating the image 90 or 270 degrees will lower the maximum frame rate

•Black & White uses less bandwidth than Color

See also the specifications for frame rates and bandwidth on page 70.
