Description
Netvox’s portable LoRaWAN® emergency push button features a simple switch button that is activated when pressed. This device uses a tact switch that is easy to operate and easy to carry. When the emergency button switch is pressed, the alert signal is sent to a centralised monitoring system via the LoRaWAN® protocol. “Safe” signals are also sent periodically to report range and battery status.
Features
- Wireless range of up to 10 km (depending on environment)
- LoRaWAN Class A compatible
- Frequency Hopping Spread Spectrum (FHSS)
- Improved interference immunity
