I don't have that model, but on the 942l I can disable http auth in the admin section then go to http://ipaddress/video/mjpg.cgi?profileid=3 to view the stream. Maybe yours is similar?
I'm not sure what you're trying to do exactly. If you want to have viewers outside the network, and you have to authenticate with your camera... you could have a local server do the auth and grab the stream somehow?
