DDNS and PPPoE Network Settings
One of the advantages of adopting DDNS and PPPoE services is to save the cost of renting a global IP
address. When you power on a camera with a video server and connect to the Internet with the PPPoE
service, the camera asks your ISP for a dynamic global IP address. This Internet-accessible IP address will be
renewed by the ISP every time you log on the Internet.
Whenever the IP is changed, the camera with the video server will notify the DDNS server of your new IP
address. A remote user who intends to connect to the camera with the video server can enter the domain
name in the web browser. The domain name will be translated to a new IP address to be used by the
camera.
Advanced Port Forwarding Technology
Communication port forwarding technology has been widely used to share a global Internet IP to other
devices on the network. The infrastructure of this technology is shown in the below figure, in which the
port 80 of the IP router is forwarded to the device with an IP of 192.168.0.10, and the port 81 of the router
is forwarded to the device with an IP of 192.168.0.11. When a remote PC on the Internet tries to access the
port 81, the user is actually accessing 192.168.0.11, private IP of given by the router.
Restore to Factory Default Settings
To restore the IP camera to the factory default, follow the below procedures:
1. Short the "Restore to Factory Default RESET" cable for 10 seconds before releasing.
2. The camera will restart.
3. Launch to IPScan Utility to search for the IP camera.
4. Access the IP camera via an Internet browser.
