The magic word in this case is H323. That's the network video/voice conferencing standard, and the tools to do this kind of thing on FreeBSD that I know of all use H323. In particular, the ohphone port. You could, for instance, set up one computer at each camera, and have ohphone displaying the incoming video from them on the monitoring computer. I don't have an ohphone setup anymore, so I don't know how much trouble getting multiple incoming video streams setup is. This solution provide four images in windows. You can use plpwm (part of the plwm port) as a window manager, which will let you rotate through the windows with a single key. Or you could use a scriptable window manager to lay out the windows in four quarters of the screen. > And what kind of machine (at the most basic) does everyone think would be > required to handle this sort of activity?

If you're going to pipe video over IP, then the end systems can be cheap - a 500MHz box is more than enough. The system running four displays is the problem. CPU load isn't much of a problem - fxtv chews up about 5% of the cpu on a gigahertz athlon box - but memory bandwidth could be a problem if you want to keep four running videos on it. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/consulting.html Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
