Port Forwarding & UPnP
UPnP(Universal Plug and Play)is a kind of network protocol to help users to find and configure
network products in the same local network area. Port forwarding is to assign a certain network
port to a network product so users can access it from outside of the Local Area Network. Generally,
port forwarding can be configured from the network router.
UPnP port forwarding is made up with finding an available network port, assigning it to a VITEK
camera and reporting overall network configuration of a VITEK camera to IP-CCTV DNS server.
Users have to register products into IPCCTVDNS server and IP-CCTV DNS service should be
enabled.
There are 3 options in UPnP Port Forwarding.
• Manual: User Assigned Port issued when users can access network router (hub) and
manually assign available network ports to VITEK cameras. In this case, users have to type
already-assigned network ports under User Assigned port.
• UPnP: User Assigned Port is used when users want VITEK cameras to configure port
forwarding of network hub with user-assigned network port. If it fails, try to change user-
assigned port
• UPnP: Auto Selected Port is used to let VITEK cameras deal with all network configurations
automatically.
Please note that the network router needs to support UPnP Port Forwarding. There is a limit for the
maximum number of UPnP devices. If it is properly configured, results will be displayed under
UPnP status.
