I have used different EZVIZ cameras and have been able to connect them to my Hikvision NVR using the "HIKVISION" protocol.
I never tried with an EZVIZ camera that had an Ethernet connection, the ones I've used are all Wi-Fi, but I'd think the Ethernet should be compatible also.
One thing though... I don't think the EZVIZ H8c Ethernet is PoE... if I'm not mistaken, you would still need to use the A/C adapter that comes with the camera.
