Can’t connect over port 8883 with MQTT over SSL
The firewall blocks
traffic using port 8883
as it’s deemed insecure.
In some cases the server/broker might not provide a specific port for MQTT
communication. It may still be possible to use MQTT over a port normally used for
HTTP/HTTPS traffic.
• If the server/broker supports WebSocket/WebSocket Secure (WS/WSS),
typically on port 443, use this protocol instead. Check with the
server/broker provider to see if WS/WSS is supported and which port and
basepath to use.
• If the server/broker supports ALPN, the use of MQTT can be negotiated over
an open port, such as 443. Check with your server/broker provider to see if
ALPN is supported and which ALPN protocol and port to use.
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.
When setting up your system, it is important to consider how various settings and situations affect the amount
of needed bandwidth (the bitrate) required.
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 can increase the product's CPU load.
• Removing or attaching the cover will restart the camera.
• Access by large numbers of Motion JPEG clients or unicast H.264/H.265/AV1 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 video streams with different codecs simultaneously affects both frame rate and bandwidth.
For optimal performance, use streams with the same codec.
• 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.
• Running multiple AXIS Camera Application Platform (ACAP) applications simultaneously may affect the
general performance.
• Using palettes affects the product’s CPU load which in turn affects the frame rate.
• Running multiple AXIS Camera Application Platform (ACAP) applications on the Visual and Thermal
channels simultaneously may affect the frame rate and the general performance.
