Some of the LinkedIn Responses are direct and on-point, and also hilariously/depressingly based depending on how you look at it:
EDIT: In hindsight, I think I should've looked into posting this in a different community.. It's closer to a silly "innovation".. soo.. is this considered FUD? I also don't support smoking or vaping, especially among kids. Original title had "privacy-violating" before the "solution".
Unless there will be disciplinary follow-up ( -> no reason for this design), I only see this going the way of de-facto scoreboards among kids.
Considering it only detects if someone in the bathroom is vaping and not who, disciplinary action just isn't really possible with your typical school restroom.
They can send people to investigate. Also you could just have someone outside. It should be fairly obvious.
It doesn't replace humans but it can compliment them. I'm not sure why people see this as a privacy issue. We aren't talking about some scary mass surveillance system here
Then why publish detection events like this? If they do start following up, all it does is warn perpetrators, and allow for fast iteration of anti-detection, to say nothing of other concerns people have mentioned (tripping other people's detectors etc.)
