Starting WebCam Server at TwinDVR
Click the Network Server button, and then select WebCam Server to display the Server Setup dialog
box (Figure 8-4).
Setting Multiple TwinDVRs in TCP/IP Mode
Click the Network Server button, and then select Extended Server. The Extended Server is to
duplicate TwinServer’s video stream and transmit it to the next TwinDVR in the same network. If there
are five TwinDVRs in the network, you should activate the Extended Server function in TwinDVR 1, 2,
3, and 4 respectively. It’s not necessary to activate TwinDVR 5 since there are no more TwinDVR
running behind it.
Setting Multiple TwinDVRs in Multicast Mode
Click the Network Server button, and then select Use Multicast Mode. The Multicast mode is now
activated. The Multicast Server is to instruct TwinDVR to obtain video streams from the virtual buffer. If
there are five TwinDVRs connected to the network, all TwinDVRs will be required to select the Use
Multicast Mode option.
