4.7UPnP 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.
