|You have to setup port forwarding to the camera in your router for outside access.|
You have internal ip vs public ip on your routers wan port. Usually you setup port forwarding by entering a name like camera, the ip address of the camera [you need to do a static ip assignment to the camera] and then you select the port number the camera is configured to listen on.
Once setup you access the camera remotely by typing http://wanipaddress:portnumber
This should be covered in the camera and router manuals.
