Found my answer here.
Now, we have just added a new feature "Camera Admin logon". After you log on www.cameraftp.com website, click on "My Cameras", you can see a link named: "Log on as Camera Admin" Click on it, and it will ask you to enter your "Secure Password". ( A secure password is just another password. By default, it is the same as your regular password. You can change your secure password to be different from your regular password. The same secure password is also required when you transfer your cash balance to another user.)
Just one question. What is the delete icon used for in the GUI when you open up My Cameras and click on a zip file?
