So I haven't done this myself, and have contemplated it, and
zoneminder is mostly what I've seen talked about.  I'm definitely
interested in whatever anybody is using.

Obviously there are a lot of non-FOSS solutions out there that are cloud based.

One issue with most of these cameras is that I think they don't output
compressed mpeg/etc video, so your server is going to end up
transcoding a lot of video in realtime - or at least transcoding
anything you want to save.  So expect it to need a fair bit of CPU.
Obviously the fewer cameras or less resolution you have recording at
once the easier that is.  IMO there isn't much point in recording
video if you're just going to get an unrecognizable face and not be
able to make out license plate numbers/etc, so if I did something like
this at all I'd want it to be 1080p or better, with good quality
cameras.  Otherwise the video you get might be fun to share on youtube
but that's about it.

You'll also want enough network bandwidth to handle it all.  One
camera isn't a big deal but if you have a bunch sending uncompressed
video then you'll need enough bandwidth to get it to wherever it gets
filtered/compressed.  That is probably more of an issue if you're
using WiFi, but I haven't looked at the numbers.

I haven't set this up myself so I could be off on some of those
details, but they're all things I'd want to look into.  It goes
without saying that you'll want storage/etc to suit your needs.
