The VDA424-UTP Video Distribution Amplifier is used to amplify and distribute any B/W or color NTSC, PAL, or CCTV video signal. The unit has two channels of Unshielded Twisted Pair (UTP) wire inputs and four coaxial BNC outputs for each input. That is two separate one input and four output video distribution amplifiers on one board. This UTP input and Coaxial cable output eliminates the need for a twisted pair "Balun" transformer at the monitor site.
