Registration
Check the MAC address of DVR from Setup>System>Description.
Please contact a distributor or an installer to register your DVR on a
DDNS Server. Register the domain name on DDNS Server.
After the domain name and MAC address of the DVR are registered
on a DDNS server, user can access the network with their own
domain name.
3-8-1. Ports
When you connect one or more DVRs to a network through an IP sharing device, each device
must have a unique TCP port number for access to each unit from outside the LAN. Also, the IP
sharing device must be configured for port forwarding so when each port is accessed on the IP
sharing device, it will forward to the appropriate DVR.
Note: This port number is listed next to the Port menu option in the Network Setup screen. If
you plan to access the DVR units only from within the same LAN, the TCP port does not have to
be changed.

Network access beyond a router
In order to access the DVR remotely beyond a router (firewall), the user must open one TCP
port for command level, live channels and storage channels. If this port is not opened
properly, user can not access DVR beyond a router.
If the DVR port number is set to 5445, open the TCP port 5445 on the router.
