Hikvision dvr with dahua analog cameras… audio issues?

Hey folks, I recently picked up three Dahua HAC-HFW1200TN-A cameras, but my old DVR, a XVR5116HS, didn’t have audio input through BNC. So, I got a new Hikvision DS-7116HGHI-M1 DVR, which says it supports audio input via BNC. Problem is, it doesn’t seem to recognize the built-in mics on these cameras. Any thoughts on why this might be happening?

Yeah, that makes sense. Mixing Hikvision and Dahua can cause compatibility issues, especially with features like audio. You might’ve had better luck with a Dahua DVR.

Don’t stress too much. You actually can’t transmit video and audio together over BNC. I had the same issue, and Hikvision support told me to use an external mic if audio’s needed. Not ideal, I know.
