Hikvision 7608 + Hikvision cube camera ...Push to talk?

[J273]

Ive just bought a hikvision cube camera with its inbuilt microphone and PIR it seemed ideal.

I have it connected to my 7608 NVR and audio from the white speaker comes out fine and works perfect. I want if this is possible to connect a mic to the red audio input on the NVR and be able to talk through the camera speaker, like a push to talk mic/speaker.


Is this possible and if so can anyone recommend me a mic that will allow me to do this from the NVR?

Thanks
