sonsor - alarm system

Security alarm made simple – no subscription, no camera, no compromise.

sonsor is the smart alarm system you simply plug in via USB and start immediately – no installation, no technician, no monthly fees. Your smartphone becomes your alarm centre: you're notified instantly via push notification whenever something is detected.

Burglary Protection – without a camera
sonsor detects motion, vibration, sound and light changes reliably – and triggers an alarm immediately. No video recording, full privacy. The integrated live mode shows you real-time sensor data so you know exactly what's happening the moment an alarm goes off.

GPS Tracker & LTE – always connected
The LTE model sends its GPS location directly to the app – perfect as a camper van alarm, RV security system, or trailer tracker. You always know where your vehicle is, even when you're not around.

Built for every location
Whether you need camper security, vacation home monitoring, workshop alarm, garage protection, boat alarm or Airbnb security – sonsor adapts to your location. Pre-configured profiles get you set up in minutes.

More than just a burglar alarm
sonsor continuously measures temperature, humidity, air quality, noise levels and detects mold risk and smoke alarm signals. Set your own thresholds and get automatic alerts when a value is exceeded – for example, frost in your RV or heat in a parked vehicle.
