Key products explained

Water sensor

The most underrated and potentially most valuable device. A €15–25 sensor under the sink, washing machine or dishwasher can prevent €20,000–50,000 in damage.

UPS

If the power goes out, the router shuts down and everything loses connection. A €40–80 UPS keeps router and cameras active for 4–8 hours.

Recommended installation order

  1. 4G router first — without connection, nothing works.
  2. UPS connected to router.
  3. Outdoor cameras at main entrances.
  4. Water sensors under risk points.
  5. Indoor camera for general house state.
  6. Door and window sensors.
  7. Configure all app alerts.
