Greetings. I have a LOREX N862ASB-Z 16 channel NVR that has stopped working. First the network port stopped working, and now the cameras. I've tried everything out there, including replacing the Realtek network switch on the circuit board. It's most likely the HiSilicon SoC that is bad. Anyway, any recommendation on an NVR that is compatible with the 8 4K cameras I already have installed around my house? I also have 2 W261AQ wi-fi cameras and the lorex video doorbell that connect via fusion, and I'm ok losing that capability since I ran network cables to those locations. I know I can order another Lorex NVR but I'm kind of over their equipment at this point.
