I got a doorbell camera with full Home Assistant support and a 180 fisheye camera for around $100 each (don't remember the exact price). I could use the built in recording until i got my NVR setup and it scaled with me. I thought they were great value.
Now, if you want just a bunch of standard cameras to cover your house with, maybe those other options are better, I'll save your post and take a look if I'm ever in the market. I'm not a camera expert, just a tech/home auto enthusiast so they work for what I want.

Essentially if you have a society that actually focuses on alternative transportation; it gets prioritized. Bike rides are the norm and don't feel like a chore, so when it's cold out people still reach for their bikes. Coupled with the municipality clearing bike paths BEFORE roads and you have the infrastructure to support it.
