LoRaWAN® Panic Button Applications

Indoor Location

LW004-PB uses Bluetooth for indoor location, its classic applications are in hotels, schools, hospitals and factories. Related personnel wear panic button, and deploy Bluetooth beacon indoors. A panic button has an RFID or NFC built-in, and periodically reports location information to facilitate the personnel location. In addition, when personnel encounter danger or emergency, the Alert can also be used to ask for instant help.

Outdoor Positioning

LoRaWAN panic button uses GPS to locate people outdoors. For example, when the site personnel into the non-work area, the management can timely obtain this information and deal with it. Moreover, when the construction site personnel encounter an emergency, they can also use the emergency button to alarm the SOS.

Indoor&Outdoor Positioning

GPS and Bluetooth are required in some scenarios, such as tracking the elderly in nursing homes. The panic button periodically reports their location. You can check whether they are in the corresponding area at the corresponding time. When they encounters an emergency, the SOS alarm can be used. In addition, when they remains stationary for a period of time, the device's Man Down function will send reminders to relevant personnel for prompt help.
