Thank you for reaching out, and sorry to hear about your loss. For the sake of convenience, we did not set up a limited SD card. So, if there is an SD card in your camera, others can insert it into a computer to view the SD content, but they won't have access to other information. If you don't want others to use this camera anymore, you can provide your order number and camera ID. We can apply for locking the ID so that it cannot be successfully added to the app again. If you need any further assistance, please feel free to let me know.
