This is like trying to do services monitoring by just looking for service time-outs - seems intuitive but lots of false positives and by the time you observe it the disaster is in motion. A watchdog timer or deadman&#x27;s switch is used in a lot of services as an alternative but would be a UX problem since it would require a form of active participation by the users. On the other hand, Disneyland had some success with tracking devices of sorts by branding them right as something beneficial to parents as well as children, so this barrier may be easy to overcome.<p>I&#x27;m also curious if computer vision algorithms could help with anomaly detection scenarios like this when the automatic response is so universal and there might be a large body of videos and photos of such events to help train machine learning algorithms upon.
