At this time, users will be able to hear audio from the camera site, even if the
audio output setting is disabled in the OSD setup menu. To start speaking to
the camera site, press and hold the DOME key. Once the DOME key is
released, the audio from the camera site will be heard again.
To terminate intercom, press the same channel key or press ESC.
NOTE: Intercom function is not available for channel 1.
4.7 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.
