Remote control of the camera, including viewing, deleting videos, or formatting the SD card, requires logging into the Tapo app with the account that’s bound to the device. Without your account information, these actions cannot be performed remotely.

If your computer also can’t read the SD card, it’s possible the card itself has become faulty. Or it may have been physically damaged? You might want to check for that possibility.

If you have a Tapo Care subscription, detection and doorbell-press videos will be stored in the cloud and can still be accessed and downloaded even when the device is offline. If not, you could look into services that specialize in SD card recovery. If you need any other assistance, feel free to reach out to our support team. Contact Technical Support
