General performance considerations

When setting up your system, 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 levels result in larger images. Bandwidth affected.

•Access by large numbers of Motion JPEG and/or unicast MPEG-4 clients. Bandwidth affected.

•Simultaneous viewing of different streams (resolution, compression, etc.) by different 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 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.
