Dear user, sorry for the inconvenience. If the App can only save the screenshots of the camera, it means that you need update or restore your App. You can also purchase the “Cloud Storage of Cameras” to let the camera store the captured video on the cloud server. You can also use the SD memory card to store the video captured by the camera; but these videos all cannot be downloaded to your phone. In addition, for security reasons (to prevent others from stealing the SD card from your camera for copying), even videos saved using the SD card are mostly encrypted and cannot be transferred to a computer or other storage medium (this is determined by the camera manufacturer). If you want to view the encrypted videos in SD cards, you can only use the playback function to play them through the App. If you are unable to save the screenshot, it means that your phone system does not authorize App storage related permissions, and you need to open all App storage related permissions in your phone system.
