Video baluns are an excellent choice for long cable runs. Standard coaxial cable is usually the best medium for transmitting video, but video over those runs is limited to about 600 feet before the quality degrades. CCTV video baluns allow signal to travel over Cat5E for several thousand feet. Additionally, Cat5E cable is less expensive and easier to pull. There are 2 types of CCTV baluns, passive and active. Passive video baluns are good up to 1,000 - 1,200 Ft. Active video baluns can extend the range to 4,000 feet, but they require external DC power.
