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.
