The only ways to access the QR code are:
1. The QR printed on the camera label.
2. The QR printed on the user manual.
3. When a device is added to the app, the option to save the QR code of the device is offered. If the user has opted to save the QR code, it can be found in the image gallery of their mobile phone.
If the QR code is lost, Ezviz has no way to retrieve it.
