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 m
ost 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 MP
EG-4 clients. Bandwidth affected.
• Simultaneous viewing of different streams (resolutio
n, compression, etc.) by many 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 215 PTZ/AXIS 215 PTZ-E
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.
