Yes that's the vid, thanks for the link.
I can't see any money savings there, aside from the 3-wire cable to the IR sensor and labour to solder it in. Unless it's to destroy the West by giving out fake negative fever results.
Somebody came up with fake firmware for a reason.
It's crazy, and totally reckless, as it risks lives. Ignoring earlier arguments (e.g. on medical grounds), as to if these head scanning thermometers (IR), are useful/safe (when NOT fakes).
It would seem to be a very dubious way of making money, by selling/producing/designing fake thermometers (IR). Because it could literally end up killing people.
Some of the really cheap Chinese stuff, is known to have potential safety hazards, such as electric shock, fire and maybe other hazards. BigCliveDotCom youtube channel, often details such things.
The front blue keyboard layout/section and its colour. Seem amazingly identical, between that video and the OPs supplied picture. Even the label on the side seems rather similar or identical.
It would be nice to see big/clear decent photographs of the inside (especially), of the OPs unit(s). So, we could judge for ourselves.
It is a bit like the jellybean cheap/plentiful, op-amp parts, which the Chinese still fake, just to save a cent or so, on the genuine parts. It just seems so silly, really.
