This gives you the pros and cons though I think it may be a little one sided.

Cost hight?

Definitely biased

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

How can CVI / TVI be analogue is using coax but sdi is digital using coax? 

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.

It's just a signal. Like tv, you can send analogue and digital down a coax
