EZVIZ being the consumer division of Hikvision, I thought I was getting something decent.
I have several cheap indoor EZVIZ cameras, and they play great with my Hikvision NVR... got 2 new C1C 1080P cameras on Amazon recently for $20 apiece.
Like @sebastiantombs, I'm also a big fan of the EZVIZ DB1C doorbell (until something better comes along).
