* Manual setting: Select this option to manually select a NAT router and enter the external
port number for the router in the field provided.
Notes:
- If you attempt to manually enter a port that is already in use, an alert message will be displayed.
- When the port is selected automatically it is displayed in this field. To change this enter a new
port number and click Save.
10) Zeroconfig
Zeroconfig allows the NVR to create and assign IP address for network cameras and connect to a
network automatically.
Zero configuration networking (zeroconf), is a set of techniques that automatically creates a usable
Internet Protocol (IP) network without manual operator intervention or special 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
Configuration Protocol (DHCP) and Domain Name System (DNS), or configure each computer's
network settings manually, which may be difficult and time-consuming.
