AXIS 212 PTZ/-V - Technical Specifications

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. Bandwidth affected.

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

To see the bandwidth and frame rate currently required by the video stream, AXIS 212 PTZ/-V provides a tool that can be used

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.

bandwidth are:

• image compression

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

• image complexity
