About Us

We're enthusiasts, who are interested in the warning technology for the civil defence, and we're uploading recordings of sirens, PA warning systems etc. on YouTube. As a part of our interest, we're constructiong our own warning devices, collect and create our own generated tones and sounds for sirens. We are primarily focused on devices found in the Czech Republic. There are four people behind the project: Jiří Knížek, Lukáš Badura, Tomáš Hradecký and Karel Pelichovský.

What We Do

​

Our Mission

Our goal is to bring quality content to the Czech and international siren enthusiast community. The Czech Republic itself lacks quality channels focusing on this topic, and in comprasion with international channels, the country has little to no specific channels regarding civil defense technology. We feel the urge to improve this, by being one of the first siren tech channels focusing on this very specific kind of interest in the country and we hope we'll be able to bring both domestic and international viewers as much infomation as we can about the system and devices used in Czechia with as many details as possible.
