Пасивен UTP видео балун

Пасивен UTP видео балун (от 100 Ома до 75 Ома)
Основнят видео сигнал използва честоти до няколко мегахерца. А балун може да се използва за свързване на видео сигнали към усукана двойка кабели, вместо използване на коаксиален кабел. Много камери за сигурност вече имат балансиран неекранирана усукана двойка (UTP) изход и небалансиран коаксиален един чрез вътрешен балун. A балун се използва също така в края на видео рекордера, за да превърне обратно видео сигнала от 100 Ω балансиран до 75 Ω небалансиран.
