If you wish to set the recorder to use a static IP address in your local area
network,
1. Choose "Static IP" from the "Connection Type" drop-down menu
2. Enter the IP address, subnet mask, default gateway address and DNS
server address for the recorder
3. Enable "DHCP Server" under "DHCP Server" if you wish to use the recorder
as a DHCP server, or leave it disabled if there is already a DHCP server in
the network .
4. Click Apply for the settings to take effect.
The recorder can detect the presence of a DHCP server upon startup. It
sets itself to use static IP address if there is no DHCP server currently
presented in the network. Its DHCP server function is also turned on at the
same time to assign IP addresses to cameras that are later connected to the
network. You can manually turn off the DHCP server function if you wish to
use a separate DHCP server.
Change the recorder's IP address would require the recorder to restart.
Restart the device under "system Options" >> "Maintenance" for the settings to
take effect.
