From physical alarm to rescue team — a fully automated process.
Two parallel paths reach the emergency services — data alerting through the server, and a direct voice call from the device.

SOS Točka uses the first available network in priority order.
Long range with low power consumption, ideal for mountains and remote areas.
Fast and reliable where mobile network is available.
Low power consumption for IoT devices with good coverage.
Optimized for low-power devices with deep signal penetration.
High-bandwidth satellite broadband that also carries VoIP emergency calls — ideal where there is no terrestrial network.
Skylo NTN — works anywhere in the world, even without terrestrial infrastructure.
A person in distress presses the red SOS button or activates the AED. The device detects the signal and immediately prepares a data packet with GPS location, timestamp and alarm type.
The device picks the best available path for the alert data — LoRaWAN over the Pi-HAT Notecard is the primary radio, with 2G/3G/4G, Cat-M1, NB-IoT, on-site Wi-Fi, Starlink and Skylo NTN as fallbacks. The data is sent to the Blues Notehub cloud platform.
The Blues Notehub platform receives the data and forwards it to the SOS Točka server via a secure HTTPS webhook. Notehub provides secure, reliable and low-power communication with IoT devices.
The server receives the webhook, verifies authenticity with the security key, identifies the device and processes the data. Location, time and alarm type are stored in the database.
The server sends an SMS with the GPS coordinates, alarm type and device identification to 112 (general emergency) or 113 (police), and an email to the regional notification centre (ReCO). The rescue team is alerted immediately.
The moment the alarm is triggered, the device checks for a broadband internet link — Starlink satellite or on-site Wi-Fi.
Over that link the device places an automated VoIP voice call directly to 112, 113 or the direct line of the regional notification centre (ReCO) — no mobile network required.
The emergency operator is reached by voice, so the situation can be confirmed and help dispatched without delay — in parallel with the SMS and email alert.
Blues Wireless Notehub is a cloud platform for IoT device management that SOS Točka uses as a communication intermediary between the device and the server.
Notehub provides secure, reliable and low-power communication with IoT devices via various network technologies.
When the device sends data to Notehub, it immediately sends a webhook to our server with the complete JSON data packet.
