I don't know what else to tell you, I said any Dahua NVR will work with those cameras since all you care about is the ability to record and play it back on a monitor with zero internet access, literally any Dahua NVR will work.
It is the lite series that we generally don't recommend, but ss long as you have 4 or less cameras and don't change the requirements of what you hope to achieve and get out of the NVR; but that is up to you to decide. We have given you all the information.
You are now in the paralysis by analysis stage
