Help finding compatable cameras

I have a HUNT NVR HNR33P8-8. Hunt is rebranded gem hikvision. Im looking for affordable 3rd party camera la thay are compatable. Im getting contradicting information regarding cameras Ive been looking at. I was looking at the ANPVIZ H Series on amazon. But, I have read that the two way audio wont work?
