I called support about not having access to my QR code

There has to be another way. I changed internet provider’s and need to reconnect my cameras. My son bolted them down and he now lives in another state. There’s no way I can get them off the house to see a pin or code on the back of it. I’ve had them three years. They are now useless. Contacted support and they said they can’t see my pin either. I guess I’ll be purchased more with another provider that can be of more assistance.
