I just read more about this, the Hungarian government was questioned about this and denied that any agreement was made. They said “VSquare is spreading fake news”, but Viktor Orbán or the police wouldn’t answer to any questions about the cameras, writes telex.hu in this article (in Hungarian)

That’s what the cameras are for. And from the previous track record of the Hungarian government, they will not do anything about this even if the people protest or resist. See what happened to the teachers. They only got a small raise not long ago because there are upcoming elections. If this happens I’m just gonna move to Austria I guess ¯_(ツ)_/¯
