Suggest which Mini NVR 4 port

Am looking for a mini NVR 4 port Poe
Have been using a DS 2CD2332 I and my N40L along with Blue Iris v4
It's time to upgrade as I will be getting another ip camera can anyone suggest a NVR

You have to be careful with Hikvision cameras and NVRs. The region code must match, so if you have Chinese region cameras you must have a Chinese region NVR. If you have mixed region cameras (e.g. some Chinese region, some western region) then you should get a more powerful PC and keep running Blue Iris.
