Video Baluns – What Exactly Are They?

Video baluns are devices that are used to convert balanced lines to unbalanced lines and vice versa. Video baluns are electronic devices used in aerial and its feeder cable and other electrical circuit elements wherein one is balanced and the other is unbalanced. The difference between a balanced and unbalanced line is that balanced lines have two conductors having equal currents in opposite directions, whereas unbalanced lines only have one conductor and that the current returns via a common ground or earth path.

Video baluns come in pairs, with one converting balanced to unbalanced and vice versa, while the other converts the signal back. Video baluns function by transforming an unbalanced video signal to a balanced frequency that originates from a different cable. With video baluns, frequencies are then balanced, transmitting a stronger signal while preventing signal interference.

As mentioned, video baluns come in pairs. They also come in passive and active forms. For example, passive video baluns are available in 3- and 2-Pair Powers, both for the camera and monitor side for security cameras. These video baluns are also cost-efficient, increasing the distance of security cameras by 1000ft using a Cat5e or UTP Cable. Active video baluns are also available, requiring Cat5, Cat6, or phone cables to function. Some active video baluns can even provide signals for up to 6000ft.
