3.5.1 Ports
For remote access (from outside the LAN or the Internet) to one or more DVRs connected to the same IP sharing device (LAN), each
DVR must be assigned a unique WEB PORT number . The WEB PORT number in the NETWORK setup screen is the port assigned to
the DVR in the IP sharing device (router) .
Additionally the DVR requires two additional ports on the IP sharing device: one to transmit video and the other to transmit
BACKUP files . The video port number is defined in the PORT entry, and the BACKUP port number is always the PORT 1 . For
instance, in the NETWORK screen shown above, the PORT number is 5445, so the DVR will use port 5446 for BACKUP .
The ports defined for a DVR, including the PORT, WEB PORT, and BACKUP (WEB PORT +1) must not be used by other device on the
local network . To access the DVR from outside the local network, the network router the must be setup to “port forward” (associate)
these three ports to the IP address of the DVR . For more information on port forwarding, see http://portforward .com/ .
3.5.2 Network types
The DVR supports three types of networks: LAN, DHCP, and ADSL .
LAN
In a LAN configuration the IP address of the DVR is static (fixed) . If your LAN is maintained by a network administrator, obtain the
static IP address from the administrator .
DHCP
Select DHCP when the IP address is automatically assigned by the DHCP server . The DHCP server assigns the IP address and other
parameters automatically to devices on the LAN not configured with static (unchanging) IP addresses .
