Troubleshooting
The product is accessible locally but not externally
Router con fi guration To con fi gure your router to allow incoming data traf fi c to the Axis product, enable the NAT-traversal
feature which will attempt to automatically con fi gure the router to allow access to the Axis
product, see NAT traversal (port mapping) for IPv4, on page 42 . The router must support UPnP TM .
Firewall protection Check the Internet fi rewall with your network administrator.
Default routers required Check if you need to con fi gure the router settings.
Problems with the H.264 format
No H.264 displayed in the
client
Check that the relevant H.264 connection methods and correct interface are enabled in the AMC

are valid for your network.
Check with your network administrator to see if there is a fi rewall preventing viewing.
Multicast H.264 only
accessible by local clients
Check if your router supports multicasting, or if the router settings between the client and the
product need to be con fi gured. The TTL (Time To Live) value may need to be increased.
Poor rendering of H.264

downloaded from the manufacturer’s website.

Modify the settings for your graphics adapter. Refer to the adapter’s documentation for more
information.

expected
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.
Check in the AMC Control Panel (H.264 tag) that video processing is NOT set to Decode only
key frames .
Lower the image resolution.
Why do I not get maximum
frames per second?
