AXIS M31 Network Camera SeriesTroubleshootingPoor rendering of H.264imagesEnsure that your graphics card uses the latest driver. You can usually download the latest driversfrom the manufacturer’s website.Color saturation is differentin H.264 and Motion JPEGModify the settings for your graphics adapter. Go to the adapter’s documentation for moreinformation.Lower frame rate thanexpected• See Performance considerations on page 22.• 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.• Log in to the device’s webpage and set a capture mode that prioritizes frame rate. Ifyou change the capture mode to prioritize frame rate it might lower the maximumresolution, depending on the device used and capture modes available.• The maximum frames per second is dependent on the utility frequency (60/50 Hz)of the Axis device.Can't select H.265 encodingin live viewWeb browsers don’t support H.265 decoding. Use a video management system or applicationthat supports H.265 decoding.Performance considerationsWhen setting up your system, it is important to consider how various settings and situations affect the performance. Some factorsaffect the amount of bandwidth (the bitrate) required, others can affect the frame rate, and some affect both. If the load on theCPU 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 thebandwidth.• Rotating the image in the GUI will increase the product's CPU load.• Access by large numbers of Motion JPEG or unicast H.264 clients affects the bandwidth.• Access by large numbers of Motion JPEG or unicast H.265 clients affects the bandwidth.• Simultaneous viewing of different streams (resolution, compression) by different clients affects both frame rate andbandwidth.Use identical streams wherever possible to maintain a high frame rate. Stream profiles can be used to ensure thatstreams are identical.• Accessing Motion JPEG and H.264 video streams simultaneously affects both frame rate and bandwidth.• Accessing Motion JPEG and H.265 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 andthe general performance.22
