Fall detectors are a form of remote monitoring assistive technology that have the potential to enhance the wellbeing of adults at risk from falling. In this paper, the ethical issues raised by the use of fall detectors are examined. The fall detection devices currently available are outlined, and a summary of how these devices require social-care services, or family carers, to respond in particular ways, is provided. The ethical issues associated with the use of fall detectors are classified under four headings: autonomy, privacy, benefit, and the use of resources.
