Good Morning, thanks for you time, I think it's a hardware problem, I have now ordered the new c510W on Amazon.

I'll put this in a place where I don't need the audio, and if one day with an update it will unlock better.

Thanks for all

Gio

  @Solla-topee hola le envíe un mensaje ya que mi cámara C500 tiene problemas con el micrófono   Gracias.

I have the same issue as lorraine. Literally installed it yesterday afternoon, Updated it straight away as it requested and audio is the worst. My other stationary tapo camera has much better audio.

I'd just set-up my c500 cctv camera few days ago and i noticed taht i'm now experiencing same issue in regards to audio receiving. The person was talking nearby the camera but can't hear it clearly even i put my phone on max volume. Please make fix of all bugs if it still going on. I have read the same issues here not been properly addressed. No need to send private message whoever is taking to fix this. It must  be universally address for the common good and satisfaction who use this and all your product. thank you.
