NVR & Cameras ONVIF compatibility

[cc13 0]

Hello,

I have some bullet cameras (Geovision GV BL220D) that are ONVIF 2.2.1.

I'm looking for a new NVR. So, I've put a look to a Dahua Model (608-32-4K) that is ONVIF 2.4.

Some people say that the cameras have to be ONVIF 2.4 too.

What's your mind about that ? Could I connect these cameras to this NVR ?

Thanks & Regards

Christian
