I did a search but could not find a satisfactory answer. I purchased an Anpvis camera which is actually a Hikvision PTZ-N2404I-DE3. I can get the two way audio (mic and speaker) to work via the camera's web page, but not though blue iris. I've tried various configurations but to no avail. Anyone have any suggestions? Incidentally, I am still using the old Blue Iris but the latest version.
