Hi,
If your home router provides a Wi-Fi network, you can set up the wired and wireless connection, and the default SSID will disappear after configuration. 
Tapo Smart Camera Unboxing and Setup Video Tapo C310&C320WS&TC65

If your home router provides an ethernet connection only, you can try to enable a hotspot Wi-Fi on your phone, then use another phone to set up the camera's wired and wireless connection. After the camera is configured, ensure the ethernet connection is working, then disable the hotspot Wi-Fi on your phone and the camera will remain to work on ethernet, and the default SSID will disappear.

Can I have an audio recording showing the normal sound, wind sound, and street noise? We will check if the camera's microphone works properly.
You can try to install the camera in a different location to see if the wind sound and street noise will be reduced.

Best Regards

Hi, 
I confirmed the info with the tech team that the default SSID won't cause security concerns because other people are unable to access the camera even if they connect to the SSID. You can access the camera on the Tapo app when connecting to the SSID because you have logged in to the Tapo app with the TP-Link ID(email address) that the camera binds to.
However, thank you very much for your feedback to secure the default SSID, I'll log it and forward it to the relevant team to evaluate.
Best Regards
