It's interesting how some technologies can be stretched to keep relevant and useful amidst new and upcoming technologies.

I once read a paper that Coax, in theory, can support way more bandwidth than what's providers make available today. But it comes down to develop and research the right transmitter/receivers, etc...

Nice article =)

Any chance to get a HD-TVI capture board to get those streams in a PC server ?

It's usually much cheaper to just use existing products to accomplish this. Most DVR manufacturers allow you to connect to their devices from a PC via RTSP, you just need to research and find the URL for the different manufacturer/models.

Here is ours which works across both IP and AHD product lines:

rtsp://<IP>:<port>/Streaming/channels/<channel #>

The IP and port are configured in the DVR's network settings.

The channel # is a number ranging from 0 ~ X depending on the device.

This is an option, of course, but were are doing video analytics and we need the best possible quality @ full framerate. From our past experiences , those DVR do not provide all streams in parallel with sufficient framerate/quality compared to raw HD analog inputs.

When will these cameras and DVR is become available to US market? And which brands will support them first?

Within the next few months. This isn't new news. The manufacturers have had internals on this since mid 2016. Most of the players have June/July launches of what I assume we'll call penta-brids? I think the intent was for people to have releases at ISC West and release May for hikua and June/July for the rebrands. That is what I have gathered from our Manufacturers and the docs we have been leaked by RSMs.

This isn't new news. The manufacturers have had internals on this since mid 2016.

You are conflating 3.0 with 4.0. See our previous coverage: TVI Launches 3MP, 4MP, 5MP Analog Cameras, Dahua Adds AHD & TVI Support With CVI 3.0.

3.0 was a bigger step forward given as you mentioned it allowed for interoperability amongst the HD analog types. 4.0 is a further improvement primarily in increasing bandwidth for higher resolution / higher frame rate combinations.
