Ethan, Derek, good test!
Note: We plan a public post later this week to call out the problems here to a broader audience.

Has there been a change to the IEC guidelines about wearing a full face shield that I missed?

Isn't it difficult to get a heat reading off something behind glass anyway? Just curious about the thermal cameras out there that get blocked when glass, or similar, is introduced.
