Sound from HIKVISION DS-2CD2135F dome camera to Synology?

[northam]

Is it possible?
I have HIKVISION DS-2CD2135F Dome IP camera and HIKVISION DS-101 mic, but have no idea how to connect them together. My schema on the attached picture apparently doesn't work.
And the sound setting is enabled in Synology surveillance station.
Any ideas?

Have you tested it in the camera web GUI Live View first?
And, in the camera web GUI, is the Video Type in Video Configuration set as 'Video&Audio' ?

Yes, it has web gui admin interface. And I have audio and video there. As on the screenshot.
I think, the mic requires 12V power, i'll rewire it, and keep you posted.

I gave up.
I tried all audio codecs, I tried three mics, I tried to switch places for mics' wires.
1) DS-101 mic powered with 12V gives static noise.
2) Mic from old headset is silent.
3) Sony EMC-CS3 mic is silent.
Only when i blow into the mics I hear the pretty quiet hissing noise.
And that's it. I don't hear anything else.

Should I replace the camera itself? It's DS-2CD2135F-IS.
