LinkedIn Q&A : How does one set up a video server to RECEIVE video streams from a set of specific webcams ?

One way to do this would be to configure each cam-connected PC as a streaming server. You could then connect from a central location to each server, and view/record the corresponding stream.

I would recommend VLC, an open-source media player which can also act as a streaming server. VLC is very widely used and available on virtually every platform. You'll find links appropriate links below.

If you need a commercial solution, Microsoft's Media Encoder will probably work too...
