AXIS M30 Network Camera SeriesTroubleshootingThe IP address has beenchanged by DHCPIP addresses obtained from a DHCP server are dynamic and may change. If the IP address has beenchanged, use AXIS IP Utility or AXIS Device Manager to locate the device on the network. Identifythe 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.Certificate error when usingIEEE 802.1XFor authentication to work properly, the date and time settings in the Axis device must besynchronized with an NTP server. Go to Settings > System > Date and time.The device is accessible locally but not externallyTo access the device externally, we recommend using 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 streamingMulticast H.264 onlyaccessible by local clientsCheck if your router supports multicasting, or if the router settings between the client and thedevice need to be configured. The TTL (Time To Live) value may need to be increased.No multicast H.264displayed in the clientCheck with your network administrator that the multicast addresses used by the Axis deviceare valid for your network.Check with your network administrator to see if there is a firewall preventing viewing.Poor rendering of H.264imagesEnsure that your graphics card is using the latest driver. The latest drivers can usually bedownloaded from 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 24.• 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.• The maximum frames per second is dependent on the utility frequency (60/50 Hz)of the Axis device.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.• 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.24
