Welcome and thank you for posting here in the Roku Community, @dlstoyer!
Thank you for raising and providing us with precise information about your concern. We're here to further assist you with this.
Firstly, may we know what QR code have you scanned? Is it the code that is posted on the box or after setting up your network connection?
For further details and information about why the QR code scan fails when adding a Roku Smart Home camera or doorbell, kindly follow the instructions posted in our Support article.
Let us know how it goes and we'll continue assisting you from there. Hope this helps!
Best regards,
Carly
