In reply to Brandon Stewart.

I have a few kinds, but most are Amcrest outdoor IP cameras: https://amzn.to/2Wtos06

They record to SD cards, and don’t upload to the cloud, so only use Wi-Fi bandwidth when I’m viewing them. I also use a Camect device to locally record and view the 9 most important ones: https://camect.com

For Wi-Fi, I blanket the homestead in a mesh of Eero routers: https://amzn.to/3b4b8V3

Hope this helps!
