9) Zeroconfig
Zeroconfig allows the NVR to create and assign IP address for network cameras and connect to a
network automatically.
Zero
config
uration networking (zeroconf), is a set of techniques that automatically creates a usable
Internet Protocol (IP) network without manual operator intervention
or sp
ecial configuration servers.
Zero configuration networking allows devices such as computers and printers to connect to a network
automatically. Without zeroconf, a network administrator must set up services, such as Dynamic Host
Config
uratio
n Protocol (DHCP) and Domain Name System (DNS), or configure each computer's
network
settings manually, which may be difficult and time-consuming.
