NVR‐820/NVR‐1620

The built-in DHCP Server function is NOT always configurable and is greatly dependant to the

connection type that is set to "Device Network Setting":

1. If the connection type is "Auto Mode", the DHCP server function is NOT configurable. It will

be ON if the NVR doesn't obtain an IP from a DHCP server in the local network and uses its own

default static IP 192.168.101.50

2. If the connection type is "Auto Mode", the DHCP server function is NOT configurable. It will

be OFF if the NVR obtains an IP from a DHCP server in the local network.

3. If the connection type is "DHCP Client", the DHCP server function is NOT configurable. It will

be OFF if the NVR obtains an IP from a DHCP server in the local network.

4. If the connection type is "DHCP Client", the DHCP server function is NOT configurable. It will

be ON if the NVR doesn't obtain an IP from a DHCP server in the local network and uses its own

default static IP 192.168.101.50

5. If the connection type is "Static IP", the DHCP server function is configurable and can be

turned on/off manually.

7.1.3 DDNS Service

DDNS, which stands for “Dynamic DNS”, is a method, protocol, or network service that provides

the capability for a networked device, such as a router or computer system (in this case, the

NVR) using the Internet Protocol Suite, to notify a domain name server to change, in real time,

the active DNS configuration of its configured host names, addresses or other information

stored in DNS.

A popular application of dynamic DNS is to provide a residential user’s Internet gateway that

has a variable, often changing, IP address with a well-known host name resolvable through

standard DNS queries.

This is useful if the NVR is placed on the Internet with a dynamic public IP, which once the

DDNS is properly set up, users can access the NVR remotely with the DDNS domain name

without worrying if the IP has changed or not.
