When an elderly man with dementia started wandering off from his Singapore home, often walking miles before being found, his caretakers were at a loss over how to keep track of him ¡ª until a tech firm suggested fitting him with a wearable GPS tag.

His caretakers also placed motion sensors in the 74-year-old¡¯s flat and a CCTV camera at its doorway so they could monitor him from a distance. The public housing building has a further six CCTVs in the common areas to watch over its senior residents.

¡°We have more peace of mind since we installed these, as we can more easily watch over them and get to them quickly in case they have a fall or wander off,¡± said a volunteer caretaker who asked not to be named, as she is not authorized to speak to the media.
