The B1 Panic Button is a portable emergency call tag designed based on Bluetooth Low Energy (BLE) communication. It can send the SOS signal immediately just by pressing the button by field workers, which can quickly respond to verbal abuse, assault and various threats in hotels, hospitals, nursing homes, and schools. Its IP65 rated waterproof and dustproof design and sturdy ABS/TPU housing make it reliable for industrial use and commercial use. Built-in acceleration sensors, RGB LEDs and vibration/booster notifications provide intuitive emergency call and communication status. Low power design and rechargeable batteries enable long-term operation in everyday use.
