Performance Considerations - Axis Q1715 User Manual

AXIS Q1715 Block Camera
Troubleshooting
The IP address has been
changed by DHCP
Certificate error when using
IEEE 802.1X
The device is accessible locally but not externally
To access the device externally, we recommend you to use one of the following applications for Windows
• AXIS Companion: free of charge, ideal for small systems with basic surveillance needs.
• AXIS Camera Station: 30-day trial version free of charge, ideal for small to mid-size systems.
For instructions and download, go to axis.com/vms.
Problems with streaming
Multicast H.264 only
accessible by local clients
No multicast H.264
displayed in the client
Poor rendering of H.264
images
Color saturation is different
in H.264 and Motion JPEG
Lower frame rate than
expected
Can't select H.265 encoding
in live view
Can't connect over port 8883 with MQTT over SSL
The firewall blocks traffic
using port 8883 as it's
deemed insecure.

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:
IP addresses obtained from a DHCP server are dynamic and may change. If the IP address has been
changed, use AXIS IP Utility or AXIS Device Manager to locate the device on the network. Identify
the device using its model or serial number, or by the DNS name (if the name has been configured).
If required, a static IP address can be assigned manually. For instructions, go to axis.com/support.
For authentication to work properly, the date and time settings in the Axis device must be
synchronized with an NTP server. Go to System > Date and time.
Check if your router supports multicasting, or if you need to configure the router settings between
the client and the device. You might need to increase the TTL (Time To Live) value.
Check with your network administrator that the multicast addresses used by the Axis device
are valid for your network.
Check with your network administrator to see if there is a firewall that prevents viewing.
Ensure that your graphics card uses the latest driver. You can usually download the latest drivers
from the manufacturer's website.
Modify the settings for your graphics adapter. Go to the adapter's documentation for more
information.
• See Performance considerations on page 65.
• Reduce the number of applications running on the client computer.
• Limit the number of simultaneous viewers.
• Check with the network administrator that there is enough bandwidth available.
• Lower the image resolution.
Web browsers don't support H.265 decoding. Use a video management system or application
that supports H.265 decoding.
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.
