datadiffusion Posted November 3, 2015 Share Posted November 3, 2015 Does anyone remember those ludicrously biassed 'cost of two wire vs conventional systems' comparisons in trade mags where they used to quote 'EOL units' at £150 each for the conventional price? So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment https://www.thesecurityinstaller.co.uk/community/topic/39296-tvi-cvi-sdi/#findComment-433721 Share on other sites More sharing options...

PeterJames Posted January 3, 2016 Share Posted January 3, 2016 SDI came along and then someone found a way to improve it they called it CVI Thats the problem with technology just a soon as you buy a 3D 60inch top of the range Samsung TV they will bring out a 4K version you buy that then they bring out the curved screen version, and so on.
