I tried that with my Aqara camera. The mic there has no windshield, though; wind noise was terrible. Also I couldn’t get Aqara support to enable higher sampling rates in the firmware than 16kHz; BirdNET expects 48kHz audio samples.

Ended up installing a better microphone attached to a RPi3A+ and using a RaspberyPi 4 which I already owned for hosting BirdNET-Go https://maciejb.me/posts/birdnet-go-setup/

Much better sound quality now!

I built an esp32 with 48khz mic soldered on, feeding rtsp stream to server in living room. Works amazing. Need to build more mics.

I like to know more about your project can you help with the details

I basically used this guide, but a different ESP32 device (so I had to change the pinout, but otherwise...). It's currently plugged into mains power, but in the future when I make additional, I'm aiming to make them solar + battery powered so I can stick them in more 'remote' areas.

Give it a go! The quality is astounding vs a security cam.

How do you transmit the audio once captured?

It's RTSP, just the audio. My 1/2 acre has wifi coverage everywhere (Uni-fi is really nice, honestly) so it just streams across the wi-fi.
