Can we talk about hacking, this being hackernews?

A few comments claim the sensors can be triggers by non-smoking events such as hairspray, nail polish remover, perfume...

If that is accurate it seems to me one could exploit that sensor flaw by purposefully triggering a false positives with some benign action - and video record doing so - perhaps a couple of times.

Then if and when smoking is alleged, obtain a log of the alleged event times, then provide video evidence that debunks at least one alleged smoking event.

A relatively small number of activists could probably create a viral nightmare for Hyatt and anyone else implementing this system.
