Good info, thanks for the replies. I have since found out that the DVR's that I am using do provide for this, but not with the included software, it's an additional download. I have been using Nuvico and was only using the Lite version of software. The full monitoring program (not "lite")will allow you to build virtual DVR's and place cam's from multiple physical devices in the order you want on one virtual DVR monitoring screen.
Thanks,
Rob
