4.5.2. DDNS
Users can use either a public DDNS server or the DDNS server operated by DVR maker
(dynlink.net) to connect through dynamic IP.
DDNS SERVER
Digital Watchdog® offers free and reliable DDNS service support. This allows you to assign the DVR a URL
address rather than a long complicated IP address, simplifying the connection process.
Check the "Use DDNS" box. The default is [DYNLINK.NET] and user can select [DYNDNS.COM] by using
drop-down list. "dynlink.net" is the fixed domain name of DDNS server operated by DVR maker while
"dyndns.com" is one of public DDNS severs. To set up DDNS, follow the following instructions:
Input necessary information based on your network environment. And then click the [SAVE] button.
①
Enable "Use DDNS"
②
DDNS SERVER : Select DYNLINK.NET.
③
TCP/IP PORT
④
DOMAIN NAME : Assign domain name for your DVR (ex. DVROFFICE). If the same domain
name is assigned, a message will appear when you click [SAVE].
"HELP" button will help you understand how to setup several important settings.
Note
For example, if you need help about how to set DDNS, click "HELP" button at the right bottom of the
menu)
IP MAPPING and EXTERNAL IP
If you are using IP Mapping and Port Forwarding (e.g. using router for internet connection), enable both
[Use Device IP Mapping] and [Use External IP] for proper connection.
SETTING AT M/S I/E
In the [Option > Setting], input DDNS address and port number. The DDNS Server address is "dynlink.net"
and the port number is "80".
In case of using sub domain name, user can type domain name + dynlink.net
.
Ex) 1. If Mac address is "00:1C:84:01:00:02"  input as "http://001c84010002.dynlink.net"
2. If domain name is "DVROFFICE"  input as "http:// DVROFFICE.dynlink.net"
: Default is 80.
