Performance Considerations
When settings 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 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 resolution and/or lower compression levels result in images containing more data. Bandwidth affected.
