ESV4 User’s Manual 67
This is useful if the NVR is placed on the Internet with a dynamic
public IP, which once the DDNS is properly setup, users can access the
NVR remotely with the DDNS domain name without worrying if the IP
has changed or not.
*Please make sure a valid DNS server has been configured under the
“Network Setting” page in order for this function to work properly.
*The NVR currently only works with free DDNS service provided by
“DynDNS”. For more information, please go to www.dyndns.com
*If the NVR is placed behind a router or Internet gateway, please
make sure port forwarding for port 80 is configured on the router or
the gat- way in order for the DDNS function to properly register with
the service. It’s often suggested to use the DDNS function in the
router/ gateway for such case instead.
*Once you have the DDNS function successfully up and running,
please DO NOT forget to configure port forwarding for the NVR web
port (default 80) and the streaming port (default 9877) in the
router/gateway for remote viewing. You can then type in
http://yourddnsdomain in the browser to access the NVR remotely for
live view.
