Thanks for your interest Emerson. I have seen some similar pages, but not that one. The most informative so far has been https://www.sighthound.com/forums/topic9676
This thread explains there are two different passwords, one for the administrator to configure the camera which includes setting the video password that is different. If one visits HTTP://<camera ip address> one is presented with a login screen and can interactively enter the admin username and password. I will expairment with appending
'snapshot.jpg?account=[USERNAME]&password=[PASSWORD]' and see what happens.

I have not been able to get the sighthound approach below
'rtsp://ipaddress/aaabbbccc.videopassword' to work yet, primarily because I don't have a browser that supports rtsp:// yet. However there are internet articles that cover this also. I'm trying to explore help on this in some of the IP camera forums, but have not reached anyone who actually has it working.
Will post back if I get a working solution.

I'm also interested that UPnP is just a local protocol. Suggests the remote application must do something else if it does not detect the camera locally. Maybe I can see that if I turn my cameras off and try to access them. After all I started this thread cause I was curious about what the Lorex program does although the end goal is seeing the video feed remotely. From the WireShark dump I have now obtained I can say that the Lorex Lview program does not appear to use RTSP although it maybe natively supported. Time will tell.
