PLANET NVR-1620 - Manual (Page 103)

Network Video Recorder with HDMI
NVR‐820 / NVR‐1620
If there's no DHCP server in the network, and the NVR is set to "Auto Mode", it
will use its own default static IP 192.168.0.20
* 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 or you can
manually turn off the DHCP server function at the bottom of this
page.
