Hi,
Currently, the Tapo C200 does not support the feature to download video clips from the SD card, and if the SD card is no longer inserted into the camera, it's unable to watch the video clips saved to the SD on the Tapo app. And if the camera has not subscribed to the Tapo Care cloud service, no video clips will be saved to the cloud server to be viewed on the Tapo app.
If you have the SD card that was inserted into the camera before, you can connect it to a computer via an SD card reader and watch the videos on your computer.
If you take pictures or record videos manually on the camera's live view page, the picture or videos will be saved on the Playback&Memory page, and you can download them to your phone's Album so you can watch them even if the camera is turned off.
Best Regards
