It's possible you are not going to the admin panel and just viewing the directory.

Try the following address:
http:///adm/file.cgi?next_file=system.htm

Rather than:
http:///adm/

As the second one is just a directory page with a green background.

The video page for my RC8030 is:
"/img/main.cgi?next_file=main.htm"

Which should have some buttons you can use for PTZ.
