Two way audio using Hikvision NVR and IPC IS model

Postby tespinosa » Fri Feb 02, 2018 8:58 am

I'm having issues getting two-way audio set up. I using a Hikvision NVR DS-7616NI and have this connected to DS-2CD2142FWD-IS cameras. I've wired the speaker as follows. RCA to Camera audio via splicing the RCA into main wire and ground. This goes to my amp then to a speaker. I'm pretty sure I have it wired correctly. Mic works perfectly. Just can't talk.

I'm using IVMS-4200. However, can't speak to IPC. When I select "start IP two way audio" I'm receiving error:
Failed to enable voice talk Error HcNetSDK dll[605]

I also wired the speaker thru NVR and chose "start two way audio". I get the same message and the MIC just broadcast the MIC directly to the speaker..

I'm also getting mixed messages as to if this is even possible using the NVR. Has anyone had any luck with this?

Really appreciate any help. This one is driving me crazy.
