Performance considerations
When setting up your system, it is important to consider how various settings and situations affect the performance. Some factors
affect the amount of bandwidth (the bitrate) 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 the most important to consider:
•
High image resolution or lower compression levels result in images containing more data which in turn affects the
bandwidth.
•
Rotating the image in the GUI will increase the product's CPU load.
•
Access by large numbers of Motion JPEG or unicast H.264 clients affects the bandwidth.
•
Simultaneous viewing of different streams (resolution, compression) by different clients affects both frame rate and
bandwidth.
Use identical streams wherever possible to maintain a high frame rate. Stream profiles can be used to ensure that
streams are identical.
•
Accessing Motion JPEG and H.264 video streams simultaneously affects both frame rate and bandwidth.
