I do a lot of work with CCTV equipment and the older equipment used to use coax and you could use an extender it was there was a baulin Transformer at each end and you could use just twisted pair between them I have cameras that are at a thousand feet of cable that have a baulin each end and the video spectrum is still just as clear as the camera that's 4 ft away from the from the recorder so I would have to say yes the twisted pair extenders were good as long as you have good baulin's in each end to adapt them.
