DDNS & Router Port Forwarding
DDNS
DDNS uses a specific domain name to access the device which has a dynamic IP
address. User can access the camera through the domain name, any dynamic IP
address changes will be automatically updated by the camera's DDNS client with the
DDNS server.
Using the DDNS service
x
To use DDNS service, connect to PittaDNS (www.pittadns.com) or DynDNS (www.
dyndns.com) and registered with one of the several free domain names.
x
Set the DDNS for the camera through Pitta WebView's DDNS settings page. (

Router Port Forwarding
IP or domain name serviced by DDNS is not accessible when the dynamic IP is the
hidden internal IP by the router. In this case, if you use port forwarding provided by the
router then you will be able to access the dynamic IP. The router's port forwarding is the
functionality to distinguish the internal IP from the router's port. For instance, you can set
the access port 80 and 81 using the router IP (121.140.158.405), access from the web
to internal IP 192.168.10.100 and 192.168.10.101. Then it can be accessed by
http://121.140.158.405:80 and http://121.140.158.405:81. If DDNS activates, it can be
accessed by the registered domain name. (
