DDNS settings 
DDNS servers allow you to connect to your recorder using a dynamic address. This 
dynamic address needs to be registered with a DNS service. The DDNS setup menu 
allows you to enable or disable DDNS and to configure it using ezDDNS, No-IP or 
DynDNS. 
Note: Some service providers block the default RTSP streaming port 554 used for 
video streaming, so if you are not receiving video images over the internet, you may 
need to change it to another value.  See Appendix C “Port forwarding information” on 
page 137 for more information. See “Port forwarding information” in the appendix for 
more information. 
There are three ways to set up a DDNS account: 
•  ezDDNS: A free-of-charge service included with your recorder and fully managed 
within the recorder interface. It is exclusive to TruVision products.  
•  DynDNS: A third-party service where users need to apply for a DynDNS account on 
the Dyn.com website. 
•  No-IP: A third-party service where users need to apply for a no-IP account on the 
no-ip.com website. 
 
Caution: If you use the services of DynDNS or No-IP, your account user name and 
password for these services will be sent to them in clear text format when you set up 
your connection in the recorder.  
Note: You cannot have two recorders with the same host name. 
To set up DDNS: 
1.  From the menu toolbar, click Network Settings > DDNS. 
2.  Select the Enable DDNS checkbox to enable this feature. 
3.  Select one of the DDNS types listed: 
ezDDNS: Click the Get URL button. The URL address to access the unit is 
displayed. If no host name is specified, the DDNS will allocate one automatically. 
The maximum length for the host name field is 64 characters. This limit does not 
include tvn-ddns.net. An example of a host name could be max64chars.tvr-ddns.net. 
- Or - 
DynDNS: Select DynDNS and enter the server address for DynDNS. In the 
recorder domain name field, enter the domain name obtained from the DynDNS 
web site. Then enter your user name and password registered in the DynDNS 
network. 
For example: 
Server address: members.dyndns.org 
Domain: mycompanydvr.dyndns.org
