Please refer to this guide: How to Download/Delete Videos from Your Tapo Camera or Doorbell

Currently, the function to delete individual video files from the SD card via the Tapo app is only supported on certain camera models. Please refer to the compatibility list at the link provided.

If your camera model is not listed in that compatibility list, then for now, the only available options to delete recorded videos are:

Format the SD card directly from the camera settings in the Tapo app (this will delete all recordings on the card).
Remove the SD card from the camera and insert it into a computer to manually delete specific files.
