The Muxlab 500009 Screw Terminal Balun is a video extender that allows a single CCTV video signal to be transmitted via a Cat3/5E/6 cable, eliminating the need for coaxial cable. Providing a hassle-free cabling solution, it connects to CCTV security / surveillance equipment that includes cameras, IP camera encoders, video switchers, sequencers, multiplexers, DVRs, and camera servers. The balun can also be used with other composite baseband video equipment such as DVD players, cable boxes, media servers and audio-video monitors.
The screw terminal balun is used in pairs to transmit standard composite video and supports transmission of color signals up to 1200' via Cat3; it can be extended to 2200' via Cat5E/6 or a higher version. For black and white signals, the maximum transmission distance is up to 1500' via Cat3 (can extended up to 2500' via Cat5/6). The balun uses 2 screw terminals.
Made of ABS fire retardant plastic, the compact screw terminal balun measures 1.75 x .75 x 1.00" (4.44 x 1.9 x 2.54 cm), and features low return loss that ensures maximum power transfer with no line faults between the input and output. Besides using Cat3/5/6 as a cost-effective alternative to coaxial cabling, the balun also makes changes / additions to modular outlet connections faster and easier.
