Advance Network DDNS and PPPoE Technologies
The advantage of using DDNS and PPPoE is to save the cost of IP address. H.264
AVC AiP camera
’s PPPoE service gets a dynamic global IP address after system reboot.
This IP address may get changed periodically. This is the address needed to access
the video server over Internet. When ISP re-assigns a new IP address to H.264 AVC
AiP camera, H.264 AVC AiP camera notifies DDNS service. A remote PC can access
H.264 AVC AiP camera by typing domain name in a browser. The domain name gets
resolved by DDNS service and gets translated to its dynamic global IP address. The
dynamic global IP address can now be accessed by the remote PC.
Advance Network Port Forwarding Technology
Port forwarding technology is an advanced network technology which is widely
used for using one global IP shared by many network devices. The network
architecture is illustrated as below. Port 80 of the router (192.168.0.10) is
assigned to the device IP address, 192.168.0.10. Port 81 of the router is
assigned to the device IP address, 192.168.0.11. When Remote PC accesses
the router’s port 86 (122.116.191.129), it eventually accesses the video server at
192.168.0.11.

1. Get IP address from ISP after reboot.
2. Notify DDNS server for the new IP address if
