Sentry2 scan code help

I can not scan the code. The label is weathered.
Is there another way to set it up?
I guess you have to scan the code on label with cell phone,
Then hold phone up to camera?

Hi, there,
Are you referring to a battery camera or a plugged-in camera?
If it is a plugged-in camera, you could manually enter the device ID on the camera when you setting it up as long as the device ID is readable.
If you are referring to a battery camera, there is no need to scan the qr code on the camera.
