There is a topic already made about that camera which can be found here .
As far as the settings not being saved, are you clicking the submit button to make sure the settings stick?
DDNS Service Settings DDNS is used for you to view your camera from Internet, what you need to do is to set DDNS for your camera, and do port forwarding in your router. At the bottom of the camera, there is a label, where some useful information can be found there, such as camera's username, remote address, DDNS password, such as: http://g7090.vipcam.org. Choose ""DDNS Service Settings", input DDNS Service, DDNS User,DDNS Password, submit it. For example :DDNS service:vipcam.org DDNS user:g7090 DDNS password:683786 If "Device Status" shows that "vipcam successed", that means DDNS Service Settings is succeed.
The second thing you need to do is port forwarding in your router, login your router, and input the camera IP address and port.
Then the DDNS will come to work, take effect.
As far as the ddns url goes, lets say that you made a ddns entry and called it my-camera.no-ip.org. You would simply type http://my-camera.no-ip.org into a web browser and it would point to your camera as long as you had the correct ports open on the router and also your external ip address matched up to the ip address that is on the ddns account.
