1. Sound Quality: You mentioned the audio isn’t clear. For optimal performance, we recommend reviewing our sound optimization guide:Troubleshooting for better audio quality of my Tapo camera
2. Incorrect Playback: This is concerning. First, could you confirm if your cameras are connected to a Hub?
3. Quick Battery Drain & Solar Panel: To maximize battery life with solar charging, we have a comprehensive battery optimization article:How to extend the battery life of Tapo Camera/Doorbell
4. Delay Notification, refer to Scenario 2 in this FAQ: What should I do if Tapo/Kasa notifications are delayed or not working?
