Does Todd know that? I guess that's why he took the red pill and partnered with Dahua. Funny, I posted essentially the same conclusion on LinkedIn and he has not responded - though he still claims HD-SDI-based HDcctv 3.0 is on the horizon <chuckle>

Of all the 'other' ones listed that's true, but there is one general exception, StarDot Multi-Channel Long Distance Coaxial (MCLDC).
No need to defend their omission from the list; you have made it clear that the technology is not now, and is not likely to be a major force in the non-ip-mp space. I just figured that I'd save Ben the trouble of responding, as well as show him that we had not forgotten the technical aspects of his product.

I just have to wonder what some of these companies are thinking. Do they really think they can differentiate themselves from one another?
It's bad enough with the primary technologies: HDcctv / HD-SDI, HDCVI, HD-TVI, etc. but when you add all of the other "HD" acronyms, do they think people just see the "HD" and aren't concerned about compatibility?

It's two way comms. So all those analog cameras that output messages to the screen on motion detection, tampering etc finally have a path to get that information back to the DVR.
Expect some level of intelligence in the cameras at some point.
Audio can also be transmitted as well.
TVI too.

In a new interview, the HDcctv only employee Executive Director has admitted that SDI is dead and that they are now focusing on Dahua CVI, noting:
"With SDI, we weren't there with convenience or price. With CVI, we have reliability, convenience, works over any composite infrastructure, and the pricing is similar too."

I sell HD-SDI, my customers love it. The distance is an issue, and legacy RG59 causes transmissin issues on longer runs, but overall, it is HD over coax with zero latency. An the most important factor seemingly ignored in this debate: it is a television standard, just like its analog cousin. This means there is a technology "backbone" in a way. So far, all of my vendors licensed to produce CVI are limited to 720P. And the 1080P is limited to 500ft or so. I can squeeze 750 out of HD SDI with extenders. I wouldn't count it out yet. Especially with the recent price drop in equipment cost. I find new HD SDI product being released all the time. One complaint, wireless transmission is quite limited, but I have found a product suite to combat that too!

John, you know I'm a fan of yours and IPVM, but I really didn't find this article that beneficial regarding weighing IP vs non-IP (I say non-IP instead of 'Analog' because HD-SDI is digital).
Instead this article felt more like, "Why IP is awesome and non-IP sucks." which really doesn't give a fair shake on the relative strengths and weaknesses. True, IP is where everything is at and going, but that should be irrespective (or at best a footnote) to this discussion.
Don't betamax the non-IP discussion by only stating the strengths of one side, then cementing it by saying that the side you just described the strengths of is what everyone's buying.
Just my 2 cents.

That said, the chart you have at the beginning was EXCELLENT and compared and contrasted the speeds and feeds very well...it was just hard to dig deeper after that.

You're correct of course about lack of Matrix, but I can see infrastructures that deal with this in a virtual matrix, but again, I'm not talking enterprise systems here, I'm talking systems fewer than 20 cameras. That's where I think HDCVI and competing technologies might have some traction.
Yes you mentioned pricing, but you weren't very granular about it.
Generally speaking I don't comment about the format or specific content of your articles, because they're generally fair and thorough. I just felt like this one wasn't. Put another way, if I were a small business owner, I couldn't make an informed decision on IP vs non-IP from the content of this article.

Thanks, this was a great article to help us make sense of the new alphabet soup.
Regarding ethernet over coax @ $150-400 per link, I don't know if these units have relevance to the professional environment, but the least expensive ethernet over coax (MOCA) adapters I have seen are these from TIVO (100Mbps):
https://www.tivo.com/shop/detail/moca $49.99 each end
Slightly more expensive is the Amazon.com twin pack @ $112.05/pair but maybe less expensive with Amazon prime free shipping:
http://www.amazon.com/Actiontec-Ethernet-Adapter-Service-ECB2500C/dp/B008C1JC4O/ref=sr_1_1?ie=UTF8&qid=1410450363&sr=8-1&keywords=moca+network+adapter
Would you trust your professional reputation to these units?
Thx.

I don't think this is right:
"Bandwidth is essentially 'unlimited' . Because the video is compressed (typically using H.264) in the camera, the output can be 3MP, 5MP, 10MP, 20MP or more and can easily 'fit' inside standard networking infrastructure (e.g., 100Mb Ethernet).
I think unlimited is not the correct adjetive here.
