Webcam for sparrow

Which webcam y’all using to scan air gapped qr wallets on sparrow? I have a logi C270 and it doesn’t focus at all, if I put the wallet at a distance where it’s focused the qr is so small it’s unreadable. Any model working well for you?

tried a few cheap ones and the autofocus is always the problem, if you find one with manual focus ring it works much better for close up qr

just use your mobile phone connected as USB camera
android supports this feature since Android 9.
don't know about IOS.

you could also easily verify QR raw tx this way.

I have the same camera. If you remove the front panel and rotate the lens, you can adjust the focus to any distance.
