These are all pretty good suggestions...a few points I'd add based solely on my personal experiences:

• A lot of Amcrest's cameras are pretty solid for the price too. I've recently ordered some rebadged Dahuas from empire tech and haven't used them a ton but so far I'm thinking I'll really like them.
• Check out night color cameras. They're not as "discreet" potentially as they generate their own visible light if it's pitch black out, but to me that's actually another security benefit...and the night time performance can be amazing.
• Blue Iris is another pretty great piece of software. Super cheap for what it offers, and while it's a little more resource heavy being a full fledged NVR, you can pair it with things like Codeproject.ai and get some amazing results.
• Double down on getting rid of wifi, if at all possible, and through any and every means possible. I too was initially pretty set on the convenience of wifi, but mixing wifi and cameras just never ends up in a great experience from everything I've ever had experience with. The absolute best I've ever seen is just "ok", and usually it's substantially worse.

Good luck!!
