- DHCP
This item allows users to obtain a dynamic IP address from DHCP
(Dynamic Host Configuration Protocol) server when the DVR boots up.
When using DHCP, the settings are dynamic and will change every time
the DVR power on or off, depending on the network's setup.
If the item is enabled (ON), a dynamic IP will be assigned to Versatile
H.264 DVR. In this case, users do not need to set a static IP and the
Ethernet settings, including IP address, Netmask, Gateway, and DNS
settings will be read-only.
If the DVR is using a permanent address, disable DHCP (OFF) to
manually set IP Address, Netmask, Gateway, and DNS. See the network
system administrators or IT personnel for appropriate values.
