Appendix G - Bandwidth

As different networks have different characteristics and different amounts of bandwidth available, the AXIS 230’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 actually 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 230 cause problems for these services?

How many clients are likely to be viewing the video stream at any one time? The maximum number of (unicast) viewing clients on a local area network is 3.

Video Quality vs. Bit Rate

The quality of the video stream in relation to the bit rate is roughly illustrated by the following graph.
