General performance considerations

When setting up your system, it is important to consider how various settings and situations will affect performance. Some factors affect the amount of bandwidth (the bit rate) required, others can affect the frame rate, and some will affect both. If the load on the CPU reaches its maximum, this will also affect the frame rate.

The following factors are among the most important to consider:

High image resolutions and/or lower compression levels result in larger images. Bandwidth affected.

Access by large numbers of Motion JPEG and/or unicast MPEG-4 clients. Band- width affected.

Simultaneous viewing of different streams (resolution, compression, etc.) by dif- ferent clients. Frame rate and bandwidth affected.

Accessing both Motion JPEG and MPEG-4 video streams simultaneously. Frame rate and bandwidth affected.

Heavy usage of event settings affects the CPU load. Frame rate affected.

Enabled motion detection. Frame rate and bandwidth affected.

Heavy network utilization due to poor infrastructure. Bandwidth affected.

Viewing on poorly performing client PC lowers perceived performance. Frame rate affected.

Access by large number of audio clients using full-duplex mode. Bandwidth affected.

Optimizing your system

To see the bandwidth and frame rate currently required by the video stream, the AXIS 243SA provides a tool that can be used to display these values directly in the video image.

To do this, special format strings are added as part of a text overlay. Simply add #r (average frame rate in fps) and/or #b (average bandwidth in Kbps) to the overlay.

For detailed instructions, please see the online help for Video & Image > Overlay Settings, and the help for File Naming & Date/Time Formats.

Important!

•The figures displayed here are the values as delivered by the server. If other restrictions are currently in force, (e.g. bandwidth limitation) these values might not correspond to those actually received by the client.

•For Motion JPEG, these values will only be accurate as long as no frame rate limit has been specified.
