AXIS Q6055-S PTZ Network Camera
Troubleshooting
No multicast H.264
displayed in the client
Check with your network administrator that the multicast addresses used by the Axis product
are valid for your network.
Check with your network administrator to see if there is a firewall preventing viewing.
Poor rendering of H.264
images
Ensure that your graphics card is using the latest driver. The latest drivers can usually be
downloaded from the manufacturer’s website.
Color saturation is different
in H.264 and Motion JPEG
Modify the settings for your graphics adapter. Go to the adapter’s documentation for more
information.
Lower frame rate than
expected
• See
Performance considerations on page 16
.
• 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.
• In the product’s webpage, set a capture mode that prioritizes frame rate. Changing the
capture mode to prioritize frame rate might lower the maximum resolution depending
on the product used and capture modes available.
• The maximum frames per second is dependent on the utility frequency (60/50 Hz) of
the Axis product.
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.
