Fall detection and SOS The bracelet uses intelligent fall detection to identify accidental falls. If a fall is detected, it automatically places an SOS call to preset contacts, providing rapid assistance even if the wearer cannot act. Electronic Fence for safety In the companion app, set a safe electronic range to protect elderly and children. When the wearer leaves the defined area, family members receive real time alerts on their phones to respond quickly. Voice call and two way communication The watch supports a 4G SIM card and enables two way voice calls. Save family numbers and make calls through the watch or via the app for continuous care of the elderly. Incoming call reminder The bracelet vibrates to alert incoming calls, helping ensure important calls are not missed even in noisy environments. Clear sound output supports users with weakened hearing. Use scenarios At home care: A senior wears the bracelet to enable fall detection, automatic SOS to caregivers, and a geofence around the home to prevent wandering, with easy two way communication for urgent needs. Safe outings: A child or elderly relative can roam within a set park or school area; if they stray beyond the boundary, parents receive real time alerts and can initiate a call through the watch. Daily communication on the go: With 4G connectivity and app based calls, family members stay connected anywhere, and incoming calls are clearly announced by vibration and sound, reducing missed communications.
