Beyond basic tracking, professional-grade watches must include Fall Detection (G-sensor) with adjustable sensitivity levels to reduce false alarms. Essential health sensors include Heart Rate, Blood Pressure, and SpO2 monitoring, with data sync capabilities to a mobile app or management platform. For institutional use (nursing homes/security firms), ensure the firmware supports Geo-fencing alerts, Two-way Voice Calling, and Remote Voice Monitoring. IP67 or IP68 waterproof ratings are mandatory to ensure the device remains functional during handwashing or accidental immersion.
