Performance considerations
When setting up your system it is important to consider how various settings and
situations will affect the overall performance. The following aspects are among the most
important to consider:
• Image resolution - High image resolution creates larger images. More data
increases the total bandwidth used.
• Image compression - A low compression level creates larger images. More data
increases the total bandwidth used.
• Clients - Large numbers of clients accessing the server increases the total band-
width used.
• Video channels - The number of video channels simultaneously accessed by cli-
ents affects the video server’s CPU and video compression load.
• Different streams (resolution, compression, etc.) viewed simultaneously by differ-
ent clients affect the server’s CPU load, the video compression load and the total
bandwidth throughput.
• Events - Heavy usage of event settings affects the server’s CPU load.
• Motion detection - This can affect performance when enabled.
• HTTPS - Increases the server’s CPU load when encrypting data.
• Network utilization - Heavy utilization due to poor infrastructure.
• Poorly performing client PC - Lowers perceived performance.
