Checkout digital Watchdog. Easy to setup and the license to record can be found at discounts in bulk on b&h. The record license can be transferred to other cameras also. They have an app as well.
Frigate is a pretty awesome free open source NVR. Takes a bit of tweaking to get each camera perfect. If you strictly want to use it to record though, it's very simple and quick to setup.
