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

Much better sound quality now!
- brewtide 16d agoI built an esp32 with 48khz mic soldered on, feeding rtsp stream to server in living room. Works amazing. Need to build more mics.
- maciejb 16d agoHow do you transmit the audio once captured?
- brewtide 16d agoIt'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.
- venmul 16d agoI like to know more about your project can you help with the details
- brewtide 16d agohttps://github.com/Sukecz/esp32-birdnet-mic https://github.com/Sukecz/esp32-birdnet-mic 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.
