This is used to select the network type (Ethernet/xDSL) connected to the DVR. Select Ethernet
when the DVR is connected to dedicated line, cable modem or LAN.
Select xDSL when the DVR is connected to a PPPoE-type xDSL line. However, if the xDSL line
is not of the PPPoE type, you must select Ethernet.
DHCP
Dynamic Host Configuration Protocol (DHCP) manages host addresses on a network. All the
hosts on a LAN use this protocol to share limited IP addresses when accessing the Internet. In
other words, a DHCP server allocates dynamic IP addresses to all the hosts on the LAN.
If the LAN has its DHCP server and the DHCP menu item is enabled, the DHCP server
allocates an IP address to the DVR.
'DHCP' is used on a LAN with a DHCP server installed. Generally, small and large LANs have
DHCP servers while small LANs use Network Address Translation (NAT) from a hub or router.
IP Addr
IP Address is used for communication between the DVR and Network Manager, and is also
used when Webviewer accesses the DVR. This is available only when Net Mask and Gateway
are set.
Net Mask
Net Mask specifies a range of IP addresses and enables IP addresses in the range to
communicate. Net Mask should be allocated by a network administrator.
Gateway
Gateway must be specified to enable IP addresses to communicate and should be allocated by
a network administrator.
DNS1
DNS1 must be specified to register the DVR to SWR while DNS Address should be allocated by
a network administrator.
Additional DNS
Additional DNS is used to replace DNS1 when it is unstable or has a problem.
