BlueIris does need some configuration but is incredible flexible. If you are a complete technophile I wouldn't recommend it (fall back to 24/7 digital DVR). But if you are somewhat comfortable figuring out something on a computer, it wouldn't be hard. It works with almost all USB cameras and POE (power over ethernet - just needs a router that can power everything, and then you only need one single network cable to each camera, no separate power cable or accomodation).

There are POE cameras that can be had in the sub $30 range that are excellent. You can also reuse old web cameras and extend those using USB extension cables up to 100' or so.

I use BI at home with some 20x PTZ cameras (SUNBA) and a mixture of various other POE. It's nice being able to get plates 300 yards away
