Right, I downloaded a panasonic setup utility, ran it in wine, and set the camera up with the username and password.
However, the utility assigned a new IP address, different to the one LMCE assigned during PnP detection. I changed the original LMCE camera IP in web admin to the new panasonic one, and it worked. Is there any crime in doing this? Will it affect other camera functions?
Just need to work out this automatic recording business now, and I'm happy.
