Port Mapping
Two port mapping methods are available:
z
Universal Plug and Play (UPnP)
z
Internal and external mapping
UPnP
UPnP enables the NVR to discover other devices on the network and
establish network services such as data sharing and communication.
To use UPnP in your NVR, you must enable UPnP in the connected router.
With UPnP enabled for Network Address Translation (NAT), the ports on
the NVR can be mapped automatically to the router, and computers can
access your NVR from outside the LAN.
