I'd recommend installing your own router. Mine is from Ubiquiti and they start at $50 ish. Dedicate a network/port/vlan to untrusted devices, don't allow any incoming or outgoing to that network except for anything you explicitly want and set up.

Then buy whatever IP camera you like. I bought 4 of the Reolink cameras for $50 ish each. Rated for outdoor use, power over ethernet, motion detection (can edit the sensitive area if you like), can be streamed to any RTSP client (like say most security software), etc. Generally plays well with others and doesn't depend on a cloud for anything.

So cameras -> RTSP -> whatever software you want.

What router is that? One of the Edge range I presume?

Ubiquiti ER-X-US 5-Port is $52 or so at newegg. I have the 6P, but that's more expensive. Quite happy with it though. They make it easy to download the text config, and of course you can keep that in git.
