General performance considerations
When setting up the camera, 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 l
evels result in larger images. Bandwidth
affected.
• Access by large numbers of Motion JPEG and/or uni
cast MPEG-4 clients. Bandwidth affected.
• Simultaneous viewing of different streams (resolution,
compression, etc.) by many clients. Frame
rate and bandwidth affected.
• Accessing both Motion JPEG and MPEG-4 video
streams simultaneously. Frame rate and band-
width 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 214 PTZ provides a
tool that can be used to display these values directly in the video image.
To do this, special format strings are add
ed 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.
