The EZ-VU Video Balun can also operate at extreme temperatures. Since the device is passive (as opposed to active) its operational performance will be unaffected by high heat (up to 133 degrees F) and sub-zero cold (-2 degrees F).

In summary, Baluns are the essential link between the CCTV equipment and the structured cabling system. Used in pairs, Baluns allow CCTV video to be transmitted via UTP (Unshielded Twisted Pair) without visible picture interference or distortion. The word "BALUN" is an acronym for BALanced to UNbalanced. Baluns convert an unbalanced signal (coax) to a balanced signal (UTP). The unbalanced signal is protected by an outer shield on coax cable. This shield protects any outside interference that hits the cable. UTP, on the other hand, does not have a shield to protect against interference. Therefore, the signal must be converted to a balanced one. In essence, baluns, when used in pairs, function as "noise" eliminators so that any interference that impinges on the individual twisted pair wires is cancelled out by the baluns. The end result is that the UTP link is more immune to interference due to the “twists” and the CCTV picture quality is transmitted reliably over extended distances.
