2 of our neighbor has those DVR systems. They love it, except it is pain in the ass to install.
Wiring running 35 to 40ft+ making a hole in not the wall.
They both got the one they sell at costco. I forgot which brand. I was about to get that.

Whereas I got arlo. Free 7 day storage (you can immediately download footage into the phone/pc). Can get budget regular arlo to arlo pro2.
Only issue I have is that it is so sensitive at low setting that it will do many false alarm on sun/shade change or tiny bugs.
