The SDR-4 is a secondary display for the SDR-3 model, designed for public spaces and high-traffic areas such as tourist attractions, beaches, water parks, and cultural or sporting events. This model is ideal for making the lightning detection system’s data more accessible to tourists and general visitors, as it can be installed on external displays like TVs and large screens.

The model supports four languages ​​(Portuguese, English, Spanish, and Italian), all available on the same screen.
