add a microphone on SD52C225U-HNI

[neketom22]

Hello,
could anyone help me to connect a microphone to my SD52C225U-HNI camera?

I have three wires on the camera:
Audio IN
Audio OUT
Audio GND

If I connect a microphone like CCTV Audio Pick Up MINI CCTV Mic Microphone pour Caméra de Sécurité de Surveillance DVR Audio CCTV Mic Câble Audio Audio Récepteur dans CCTV Accessoires de Sécurité et Protection sur AliExpress.com | Alibaba Group

I need another power supply or the camera will feed it automatically?

If I just plug the IN and GND I can hear the sound from my PC or from my smartphone?

finally, it is necessary to place the microphone in the box of the camera or outside?

thanks in advance

Tom
