Vizit is a well-known brand of domofon intercom panels installed at the entrances of apartment blocks across Russia and other post-Soviet countries, where visitors use them to call a flat before being buzzed in. Recordings of its distinctive ring have circulated online as a recognisable shorthand for that everyday entrance ritual, especially in Russian-language videos, memes and soundboards. Like door knocking, it instantly signals that someone is outside and waiting, which is why creators keep returning to it for arrival, delivery and unexpected-visitor scenes rather than using a generic bell.
