Network Video Recorder with HDMI
NVR‐820 / NVR‐1620
service that provides the capability for a networked device, such as a router or
computer system (in this case, the NVR) using the Internet Protocol Suite, to
notify a domain name server to change, in real time, the active DNS
configuration of its configured host names, addresses or other information
stored in DNS.
A popular application of dynamic DNS is to provide a residential user’s Internet
gateway that has a variable, often changing, IP address with a well-known host
name resolvable through standard DNS queries.
This is useful if the NVR is placed on the Internet with a dynamic public IP,
which once the DDNS is properly set up, 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 gateway 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 viewing.
