I'm making a project, a surveillance camera with audio. Live feed from my localhost webpage. the live camera part is now okay and working, my problem is the "intercom" part. I don't really have a sure idea if it will work, so I'm here to ask. Is it possible to put a speaker and mic with raspi so I can hear the audio from my camera. And for the speaker, so that I can speak through my mic in localhost and can hear from the raspberry pi. so it's like an Intercom. just think it's like the IP cctv that has audio. Please help me and guide me. Thank you.

PS. I'm using a raspi camera for my live footage so it doesn't include audio.

    Welcome and nice to meet you. Ah, let me summarize you problem. You project is in two parts: (1) Rpi camera, but does not include audio, so a separate microphone is needed, and web server, completed OK, (2) Intercom part and you are not sure how to use Rpi (perhaps python) to interface with microphone (might need accompanying mini audio power amplifier) and loudspeaker. / to continue, ...

    Hi #Johannes Remotigue, Thank you for your encouragement and feedback. About the the speaker connection: The link you mentioned is a USB sound card. You connect it to the Rpi USB connector, then it becomes a USB connected, external "sound card" to which you can connect (a) Microphone, (b) a speaker (system). This USB sound card is better than the Rpi's built in/internal limited function sound card, because Rpi built in/on board sound card has only the 3.5mm connector to connect a mono speaker, but no microphone. So you need the adapter to connect the mic and speaker(s). Also more HiFi.

    I'm sorry for asking too much. so If I'm going to use that USB external "sound card", like this shopee.ph/…. Is there a need still to use the analog to digital converter module? Commented Aug 18, 2020 at 4:20
