Thanks for the reply. My follow-up didn't appear to get posted, so here's another attempt. I've looked at DVRs, and they won't cut it. We'll want at least 30 users viewing feeds simultaneously. Each will view a subset, but each camera will be viewed by 10 people. Combining multiple feeds saves bandwidth (since we'll make the images smaller) and ensures they are in the same order for everyone. That makes configuration of each station easier, too. We'll want all channels recorded (2-weeks of HD video per camera). PCs are easier to maintain for us, since we have hundreds of them. Fixing them is also much easier, and adding storage is very easy (e.g. a disk shelf with several hundred TB with RAID.) A video proxy is sort of what we want, although one that combines it with recording would be more convenient. I just can't find details on products that do this. I have looked into HIKVISION based on your comment, although the web site provides almost no useful information as to the capabilities of the software.

I see there are several packages out there for PC-based CCTV solutions. In addition to recording, I want the ability to group sets of cameras into a virtual feed that is then streamed to several computers for monitoring. I want to have several groups of these for different users. I've looked at the web sites for some products, not I can't determine which products can handle this. I want at least 6 groups, each having 4-20 cameras. I'd like to have them arranged in a specific way and then serve one video stream containing these smaller images to any PCs on our network that want to view. Even better would be the ability to click on one image and expand. We'd definitely prefer in a web window, but desktop software could work assuming it supports Macs and PCs.
