One more thing about zoneminder: after installing it on an FC19 system, I don't see anything that I could immediately identify as a driver. *HOW* does it get the video? In motion, the very lightweight package, it's using V4L2, and the drivers, gspca*, are part of the kernel these days. If ZoneMindar is using the same drivers, then I'd expect that it would occasionally, after an update, wind up with the same problems motion does.
In the zoneminder web console, click the 'Add New Monitor' button. In the 'Monitor' dialog, and the 'General' tab, click the pulldown by 'Source Type' and select 'local.' In the 'Source' tab, enter the video device path and select the 'Capture Method' (V4L1 and V4L2 are both

On the other hand, if we get *new*, higher quality cameras, it'll be different drivers to worry about. <g>
Btw, I'm now also looking at lower-end video capture cards, like the Hauppage Impactvdb, model 188 (four bnc inputs). For that, what I haven't found out yet, is whether it provides the cameras one at a
time, to be
switched among, or if all four can stream at the same time, which is what we *must* have.
You need a capture chip per simultaneous channel. Most of the low-end '4 input' cards have one chip and a 4 to 1 mux.
Linux Media Labs has a four-chip card at a pretty good price point, and they specifically support zoneminder. See: http://www.linuxmedialabs.com/product_details.php?prodid=350 for the specific card, which is $165, and a lot less than the previous 4 channel LMLBT44 card was (we have three of the LMLBT44's, and paid ~$400 each for them ten years ago, but they're half that price now. Oh, and they all three still work fine.).
Bing! THANK YOU!!! That *is* in our price range, and is exactly the kind of thing I've been trying to find, *and* I see it support both ZM *and* Motion.
