AXIS 250S User’s Manual

Bandwidth

Appendix G - Bandwidth

As different networks have different characteristics and different amounts of bandwidth

available, the AXIS 250S’s video and audio settings may need to be adjusted to suit the

prevailing conditions.

The Video Quality Level

The video quality level describes how much video data is transferred per second, and can be

set in the range 1-7 (lowest to highest). Whether or not you should use the highest available

level depends on the answers to a few questions:

Does your application need a video stream at the highest quality? Try viewing the live

video stream and uploading MPEG-2 files using several different quality levels.

Are there other bandwidth-dependent services running on the same network? Will the

quality level used by the AXIS 250S cause problems for these services?

How many clients are likely to be viewing the video stream at any one time? The maximum

number of simultaneous (unicast) viewing clients on a local area network is 3.

Image Quality vs Quality Level

The quality of the video stream in relation to the set quality level can be roughly illustrated

by the graph below.
