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 clients. Bandwidth affected.

• Video channels - The number of video channels simultaneously accessed by clients affects the video server’s CPU and video compression load.

• Simultaneous viewing of different streams (resolution, compression, etc.) by different clients. 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.

• HTTPS - Increases the server’s CPU load when encrypting data.

• Heavy network utilization due to poor infrastructure. Bandwidth affected

• Poorly performing client PC - Lowers perceived performance.

Optimizing your system

To see the bandwidth and frame rate currently required by the video stream, the AXIS

240Q 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.

AXIS 240Q - Technical Specifications 57

Frame rates - Motion JPEG

The AXIS 240Q has a frame rate of up to 6/5 fps per channel for all resolutions.

Bandwidth

As there are many factors affecting bandwidth, it is very difficult to predict the required amounts. The settings that affect bandwidth are:

• the image resolution

• the image compression

• the frame rate

• the analog cameras connected to the video servervideo server

• the audio settings

There are also factors in the monitored scene that will affect the bandwidth. These are:

• the amount of motion

• the image’s complexity

• the lighting conditions.
