MultiCast Mode
Multicast Network is more complicated and expensive to setup. In the Multicast mode, the TwinServer
transmits video streams in packets to a virtual buffer of the Multicast network. The virtual buffer then
broadcasts the video streams to all TwinDVRs under the network. Each TwinDVR should be installed
with two network cards. One is for the hub where TwinServer is plugged in, and the other for a DSL or
ISDN modem with dedicated ISP service to the Internet. Each TwinDVR serves its own group of
WebCam Clients.
