The camera is an Axis 2100. I've just (eventually) had the chance to upgrade to v7beta5 and it has made no difference - yet again! I'm going to have to park this for a while but I really do appreciate your help guys.
Tom, I have used an AXIS 2100 successfully, remotely with SME Server 6.0.1.
I established a port forwarding rule that pointed incoming requests for the IP and port of the camers (example 192.168.0.50 port 8080) was available through the public IP of the server on port 8000 (again, an example).
At first it failed yo connect until I realised that the connection was being blocked by my router's firwall settings.
I decided to kill the firewall in the router in preference for the SME's own firewall by configuring the router with a DMZ address that pointed to the server's external address.
After this, all was well.
Does this move you further forward or are you still stuck?
Let us know and good luck.
Chris
