I like Reolink. it has AI and vehicle detection. 4 cams with 6tb hard drive is about $600.

pretty easy to set up as seen here https://youtu.be/XXpYhUU02G4

wifi is awful. consider getting a ethernet over powerline as seen here https://www.amazon.com/NETGEAR-Powerline-Adapter-Ethernet-Passthrough/dp/B0778Y6K6N/

if you have a lot of coax in the house, for cable TV, you can use MoCa adapter too!

I'm just gonna buy this cheap power supply. I think it comes with a power cable: https://www.newegg.com/evga-400-n1-100-n1-0400-l1-400w/p/N82E16817438038?Description=400%20watt%20power%20supply&cm_re=400_watt%20power%20supply-_-17-438-038-_-Product&quicklink=true

I'll also buy the cool Netgear ethernet thing: https://www.amazon.com/NETGEAR-Powerline-Adapter-Ethernet-Passthrough/dp/B0778Y6K6N/ref=sr_1_3?crid=2ZWZYB86SSO2R&keywords=netgear%2Bpowerline%2B2000&qid=1638829363&sprefix=netgear%2Bpower%2Caps%2C274&sr=8-3&th=1
