AXIS 231D+/232D+ - Technical Specifications 57
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
•Simultaneous viewing of different streams (resolution, compression.) by different clients. Frame rate and bandwidth affected.
•Accessing both Motion JPEG and
•Heavy usage of event settings affects the CPU load. Frame rate 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 231D+/232D+ 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) 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.
Frame rates - Motion JPEG
The following test results show the frame rates in frames/second (fps) for Motion JPEG streams from the AXIS 231D+/232D+, using a compression level of 50%. Note that these values are guidelines only - actual values may vary.
