AXIS 225FD - Video and Image Settings 19

To compensate for the lighting conditions, the white balance, the exposure control, the exposure area and the IR cut filter can all be adjusted. DC-Irisshould always be enabled, except when focusing, or when using a non-DC-Iris lens.

The settings for low light behavior determine how the camera will behave at low light levels. These settings all affect video image quality and are basically a measure of how much noise to allow in the video images.

Please see the online help for further information on these settings.

MPEG-4 Settings

These are the tools for adjusting the MPEG-4 settings and controlling the video bit rate.

The MPEG-4 standard provides many different coding tools for various applications in different situations. As most MPEG-4 clients do not support all of these tools, it is usual to instead define and use subsets for different clients or groups of clients. These settings allow you to define the type of viewing client to use.

Adjusting the maximum bit rate and setting it to variable or constant is a good way of controlling the bandwidth used by the MPEG-4 video stream.

For more information on these advanced settings, please see the online help, and Video Stream Types, on page 11.
