Hello all, I used to work as a night auditor, but I now travel frequently for a new job. I have developed a small hobby of trying to spot vape detectors in the hotels where I stay. I am curious how common they have become, which brands or systems properties use, and where they are usually installed. Do most hotels place them only in guest rooms, or also in hallways, public restrooms, stairwells, and other common areas? I would appreciate hearing about your experience, including whether they have been effective and how often they create false alarms. Thank you!
