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 router 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.
3-8-2. Network Types
3-8-2-1.STATIC
1. For the use of fixed IP.
See your network administrator if you do not have this information.
2. When DVR is installed in IP sharer that is connected with ADSL, a user can assign fixed IP to DVR
from IP sharer itself using “DMZ” function out of such sharer.
Input IP set in DMZ on
“IP” field and Gateway of ADSL modem on “Gateway” field. Similarly, for Subnet
Mask, DNS address, input relevant values in IP sharer.
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 Router
In order to access the DVR remotely beyond a router (firewall), the user must open TCP port for
command level, live channels and storage channels. User need to open 2ports numbers.
If the DVR port number is set to 5445, open the TCP port 5445 and 5446 on the router.
If this port is not opened properly, user can not access DVR beyond a router.
If DVR supports remote setup function over the network, user need to open additional port 5455 which
is the 10 th number from the basic port number.
