Gen II Dahua HDCVI Cameras - What Is New / Different?

On Dahua's homepage, there is a graphic announcing "HD over Coax 2.0". It goes on to say "Gen II HDCVI Camera" and lists four features:

  • TX-chip embedded with ISP
  • Comprehensive product portfolio
  • 1080P
  • Support WDR

This is confusing to me:

  • I don't know what the significance of a transmit chip being embedded with the image signal processor might be, and how that might or might not differ to the Gen I cameras.
  • 1080P has been available for months and not just since the mention of Gen II camera arose.
  • I don't see any WDR support in the specs of the newer cameras. In fact, there is only one model which touts WDR support, HAC-HF3101, and it is a relatively old box camera.

Can anyone tell me if there really is "HD over Coax 2.0" and whether this means some kind of new standard with extra capabilities. Perhaps this is just marketing hype?

I can see for myself that some of the new camera models now come with options for varifocal lenses, and motorized varifocal lenses. The pixel resolution has also slightly increased in some cases. However I don't see any WDR support, nothing different about 1080p support, and no obvious increase in capabilities to the signals that can be sent via HDCVI so I'm wondering what this all means, if anything. Thank you for any insight you may offer.
