6. NETWORK
A static service consists of an IP address that remains constant for the duration of the
contract of the internet service, whereas a dynamic service has an IP address that changes
every time a new connection is made through the provided modem, or recurrently in a given
period of time. Though most internet service providers offer both solutions, this manual will
distinguish between the two solutions, according to the commonly available service types, to
configure the DVR for the networking purposes.
6.1. ETHERNET
1. Static IP
If a Static IP is selected, the following settings are available:
1) IP Address: Enter the static IP address
2) Netmask: Enter the IP address of the subnet mask.
3) Gateway: Enter the IP address for the internet gateway server.
4) PRI.DNS Server: Verify the name of the domain name system.
5) SEC.DNS Server: Enter the IP address of the backup domain name system
(DNS) server that the DVR will use to convert name to IP address. This server is
used if the primary DNS server fails.
<Note> if you do not set up the DNS server correctly, it will have problem with mail
sending.
2. DHCP: Dynamic Host Configuration Protocol.
It is automatically set on from Local DHCP if there is a Local DHCP server (i.e. the
local Router). If DHCP is set to ON, the IP address, Gateway and subnet Mask are
assigned by the DHCP server (i.e. the Local Area Network Router).
