Connectors
Network connector
The Axis product is available in two variants with different network connectors:
D-coded M12 connector with Power over Ethernet (PoE).
NO NO NOTICE TICE TICE
Due to local regulations or the environmental and electrical conditions in which the product is to be used, a shielded network
cable (STP) may be appropriate or required. All cables connecting the product to the network and that are routed outdoors
or in demanding electrical environments shall be intended for their specific use. Make sure that the network devices are
installed in accordance with the manufacturer’s instructions. For information about regulatory requirements, see the
Installation Guide available at

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.
• 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.
• Heavy usage of event settings affects the product’s CPU load which in turn affects the frame rate.
• Using HTTPS may reduce frame rate, in particular if streaming Motion JPEG.
• Heavy network utilization due to poor infrastructure affects the bandwidth.
• Viewing on poorly performing client computers lowers perceived performance and affects frame rate.
• Running multiple AXIS Camera Application Platform (ACAP) applications simultaneously may affect the frame rate and
the general performance.
