Before trying the camera see if you can access a FILE on your computer when accessing the machine remotely.
Test if your port forwarding works by trying to RDP to your home computer -- set the home computer to allow incoming remote connections.
I've got a feeling however if you are using Windows 7 Home edition you won't have much luck as RDP won't work for INCOMING connections unless you have Windows 7 Pro or higher.
A way round that is to install say XP Pro as a Virtual machine (doesn't take much space and VMware player is free) - then port forward to the VM XP machine and start your camera up with the application you usually use (install the app on XP).
Otherwise an upgrade to Windows 7 pro will be required.
(Another way is to set your home machine up as an Internet server (IIS) but that's another whole issue you really don't want to tangle with at this stage).
(I know it's a Windows 7 Forum but a cheap upgrade to W8 Pro for 40 USD might be also a solution !!).
Once you get up and running this little app should open nearly every webcam on the planet (Usb ones -- whether built in to the computer or externally attached).
I think all your problems stem from the fact that the Internet address your router presents to the internet is YOUR ISP provider's IP address they've assigned to MACHINE which might not accept incoming connections.
what programs that use things like DYN-DNS / NO-IP or similar is that every so often you have a small program working on the HOME PC which sees if the IP address has changed, then forwards that to the DYN-DNS / NO-IP or other software which then updates your site address with the current IP of your machine.
For example your assigned internet domain via NO-IP / DYN-DNS etc www.dogsbody.is
your home IP address is changed by your IP provider at various times say itsa now www.xxx.yyy.zzz
what happens is that www.dogsbody,is
is now assigned to the latest IP address your IP has given you.
You'll find also on the router your networks should have the IP addresses (internal) 192.xx.yy.zz or whatever.
so in any case if the camera is a stand alone device you will need to know what address it is on your HOME LAN. If your router is ALSO dynamically assigning IP addresses then you are hosed up as well -- so you need to say have some FIXED addresses for devices like network printers and cameras.
Assign STATIC local IP addresses to your network devices.
I'm not sure how you set this up but if the camera is attached or operated via your main machine rather than just by using IE then you've got problems as the main machine won't accept incoming connections-- the LAN will of course.
If it's a pure network device provided it's got a FIXED stand alone local IP address it should work.
Even your phone should be able to access it with a web browser.
