CCTV Video balun:
The CCTV video balun allows CCTV video signals to be transmitted via a single unshielded twisted pair (UTP) cable for more versatile cabling.
Used in pairs, the CCTV balun eliminates traditional costly and Bulky coax cable, allowing CCTV security and surveillance equipments to be connected to any convenient modular outlet. 
CCTV Video balun works with analog baseband video equipment: CCTV cameras, video multiplexers, scan converters, signal boosters, video switchers, monitors; NTSC, PAL or SECAM systems.
