Hi,
If you have several APs and they use the same SSID & password, it may be the camera is connected to another AP so the speed drops.
You can lock the camera to the nearby AP and check if it helps.

Hi,
It's recommended to contact your Google device's support to know the detailed steps.

  @Solla-topee I dont know how the Google Wifi mesh can force the Tapo camera to connect to a specific AP (node)...This basically is the Tapo camera should connect AP with strongest signal, logically the closest AP.

Hi,
Because the camera is connected to a mesh Wi-Fi network, the Google device may recommend the camera to roam when it detects Wi-Fi signals from different APs around the camera. The camera won't compare WiFi signal strengths, and when the Google device recommends it to roam, it may roam to another AP. 
Therefore, I recommend that you contact your Google device support to check whether you can force the camera to connect to a specific AP.

If you confirm that your Google device does not have this function, please confirm:
1. How many Google APs do you have?
2. How many 2.4G SSIDs in your home network?
3. Please describe your network diagram.

I'll then escalate your case to our tech team for further analysis.

Best Regards
