To access my cameras directly, I use their IP address, which leads to a login page that asks for User Name and Password. That page is:
http://192.168.1.124/doc/page/login.asp
after typing in my info, it goes to page
http://192.168.1.124/doc/page/main.asp, and on this page it contains the camera video live in a window, with menu options around the periphery of the window. I know the first time I ran it, I recall Win7 asking to approve using a codec or something to see the live video.
When I try to go direct to the second page while not logged in, it redirects to the login page.
The camera is MCNB2153
Does this help?
