The European Championship games are in full swing. A total of 51 football matches will be held in Germany as part of EURO 2024. Even after the tournament, large events and concerts will regularly take place in the stadiums. These are true festivals of superlatives, and high visitor numbers are expected accordingly. To ensure the safety of visitors at all times, the managers of several train stations and stadiums in Germany decided to deploy A's crowd monitor. This system anonymously monitors the flow of visitors and alerts security personnel when the number of visitors reaches critical levels. This enables early implementation of relief measures and ensures that fans have enough space. We are pleased that our system contributes to the safety and success of this sporting event.
