Natural disasters are becoming more frequent and political uncertainty is also increasing worldwide. It has been shown in the past that sirens can reliably warn people of impending danger. Even in times when almost everyone uses the Internet and has a cell phone, there is no certainty of being reachable at all times and in all places. The alarm of an electronic siren is unambiguous. Digital electronic sirens, with their alarm function, are therefore the first means in the warning chain.
Countries whose coasts are threatened by tsunamis, earthquakes or flooding, for example, have often relied on sirens for years. As a result of the changed danger situation, the importance of the siren is also increasing significantly again in Germany. Siren networks are once again being modernized, expanded and rebuilt. The importance of the electronic outdoor siren issue is also reflected in the federal government's funding program, which has earmarked 80 million euros for the expansion of Germany's siren network. This sum is often supplemented by additional funding pots from the federal states.
