UPnP Function
UPnP is the abbreviation for Universal Plug and Play, which is a relatively
new technology that integrates 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 PCs can connect to the DVR via the
remote control software by directly clicking on the icon representing the DVR
in <
My Network Places
>
folder.
