OP: if you don't end up going with a Ring, Nest, etc. type solution, I'd go with standalone IP cams and a dedicated NVR.

The latest/greatest is the 24/7 Color offering from LTS:

Attached you'll find a screenshot I took of one I have up at a car lot in the Northeast. In this pic, there are (3) traditional 4MP IR mini dome cams and (1) of the 24/7 Color turret cams I mentioned above. This shot was taken at 3 AM after a rainstorm...yeah, it's that good.

Cost is ~40% more than a traditional 4MP turret, but the results speak for themselves.

Either way, go LTS for cams for sure. They are a US based company and if you buy direct from them, you won't have to worry about receiving a hacked/bricked Hikvision or Dahua from other random vendors on Amazon or eBay. I'd also go with turrets over dome cams for a number of reasons (ease of install, much less chance of water penetration, no IR bounce back, etc.).

If you have a spare Windows machine kicking around, no need to buy an NVR either; just load this free VMS software onto it and you'll be in great shape:
