UPnP (Universal Plug and Play) and Auto Private IP Setup (NAT Traversal)
UPnP stands for Universal Plug and Play, which is a relatively new technology that indicates a universal protocol for
widespread plug-and-play devices to ease the network implementation. When a PC and a DVR both installed the UPnP
function, the PC can automatically recognize the DVR in the same local area network. The advantage of this function is that a
PC can connect to the DVR directly by clicking on the icon representing the DVR in <My Network Places> folder as shown
below. The first five characters of the file name of a detected DVR is subject to a firmware version
Simply double click on the desired icon. Then, it will open an internet browser that connects to the DVR via the remote control
software as shown below. Please type in your User ID and Password to login and click 'Connect' button to connect.
Auto Private IP Setup (NAT Traversal)
The UPnP NAT Traversal function will help to automatically setup a router if the DVR connects to the internet via a router.
When a PC connects to a DVR, which is not in the same local area network, a real IPO address and corresponding port
number is required. However if the DVR is behind a router, the communication between the PC and the DVR will be
transmitted back and forth by the router. The router will need to setup port mapping (Port Forwarding) before images from the
DVR is remotely viewed on the PC. For each individual DVR, the setting needs to be done individually.
If the DVR has UPnP NAT traversal function, the setting of the router will be done automatically when it is enabled.
Just check 'Auto IP (NAT Traversal)' check box in the UPnP setup menu. Then it will take care of Auto IP detect by itself.
