I found this deal on Costco for 4k system, currently on sale for $650:

https://www.costco.com/lorex-4k-uhd-...100675117.html

8 - Channel 4K Ultra HD NVR with 2TB HDD

8 - 4K UHD Smart Deterrence Cameras (Warning Light + Siren)

Smart (Person and Vehicle) Motion Detection

Smart Home Compatibility

Local Storage with no Hidden Cloud Fees

Limited number of mixed reviews, but it's Costco so you can take it back if you're not happy.

As I wrote earlier, you'll probably need additional lighting.

EDIT: Or this 16 channel system with motorized optical zoom, just over $1k after coupon CYBER25:

No Costco return policy with that one though
