SOS Falling Watch
Emergency SOS smartwatch for fall detection
The SOS Falling Watch is a smartwatch-style wearable device that detects falls and impacts, automatically sending emergency SOS alerts to predefined contacts.
Using advanced accelerometer algorithms, the watch can distinguish between normal activities and actual falls, reducing false alarms while ensuring real emergencies are detected.
The device features a compact design, long battery life, and simple one-button manual SOS activation for situations beyond fall detection.
