60 AXIS 210A/211A - Technical Specifications
General performance considerations
When setting up your system, it is important to consider how various settings and
situations affect performance. Some factors affect the amount of bandwidth (the bit rate)
required, others can affect the frame rate, and some affect both. If the load on the CPU
reaches its maximum, this also affects 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 camera’s 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’s lowers perceived performance. Frame
rate affected.
Optimizing your system
To see the bandwidth and frame rate currently required by the video stream, the AXIS
210A/211A provides a tool that can be used to display these values directly in the video
image.
