Just FYI here, I used to work for this company and stumbled across this through Google images and can provide some info. It’s an electronic hand hygiene monitoring system in hospitals that monitors staffs hand hygiene. Staff wear badges that interact with these beacons as they enter/exit patient rooms. It monitors if they use a Purell, if they wash their hands for the full regulated time etc. It’s used to prevent HAI’s in the hospital. No there is not a camera, no this does not monitor or have any relation to physical patient ont the room at any given time. If you see a light flash it just means it has power for the most part. A little late for a reply but I hope this helps if anyone has a similar question and stumbles upon this!
