2-8-1. Port, Network Audio Port and Web Port

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.

Web viewer Network access beyond Router

In order to access beyond Router (Firewall), user must open 1 TCP port that is set on NETWORK >

WEB PORT. If this port is not open properly, user can not access DVR using direct Web viewer

(Example: When NETWORK > WEB PORT is set as 80, 80 TCP port of IP address of DVR must be

open.)

Network access beyond a router

In order to access the DVR remotely beyond a router (firewall), the user must open TCP port for

command level, live/storage channels. User need to open port number 5445 and 5445.

If the DVR supports remote setup and upgrade function over the network, user need to open additional

port number 80.
