1. A method of close-proximity monitoring of a subject, the method comprising:
transmitting a signal from a subject-worn beacon that is secured to a subject in a tamper-resistant manner that prevents the subject-worn beacon from being removed by the subject;
receiving the signal by an observer device worn by an observer;
prompting the observer to record a subject observation at an interval of not more than 20 minutes or less; and
emitting one or more alerts from the observer device when one or more of: the received signal indicates that the observer device is further than a predetermined range from the subject; and the observer does not record a subject observation within a predetermined observation time.
