Was there any increased CPU usage on the client? Does choosing H.264+ have any effect on the cameras ability to deliver multiple streams or higher frame rates?

A methodology question:
In the H.265 tests, the h.265 camera were compared to mainstream h.264 cameras from different models and from other brands. The key conclusions of the report came from this comparison, not from the cameras own h.264 performance vs h.265 performance:
explaining
Though in this tests there are no comparison to mainstream h.264. We only have comparisons among h.264+ capable cameras, switching between h.264 and h.264+ of the same camera to draw conclusions.
This would seem to set the bar higher for the h.265 cameras, then h.264+ cameras, no?

So for now it seems H265 has a competitor to "enhanced" H264 methods, but wasn't one benefit of H265 supposed to be you only needed one stream from which you could pull different resolutions, such as high-res for recording and low-res for viewing?

I recently installed 4 of the new 4MP value plus cameras and enabled h.264+. I installed them on a Milestone system and noticed a significant delay in the video streams "starting" in the viewing client versus turning h.264+ off. Anyone else try this out in Milestone and experience anything similar? Running the 2016 Smart client on a Core i5 with HW Acceleration enabled. I ended up disabling h264+ for the time being due to the delay being pretty bad at times up to 30 seconds or so when double clicking on a camera to enlarge then going back to a multi-view. CPU wasn't high just a long delay...

Thanks for the test and report. H.264+ turns out to be useful and probably more and more low cost H.264+ cameras will come out soon.

It's very funny to compare h.264+ with h.265, since the same technology that h.264+ used can be used for h.265 as well.

The fact that H.265 is more advanced does not mean it has to be successful in business. The same fact happened to MPEG-2, which had been used in the broadcasting industry for super long time, even if MPEG-4 was proved to be much more efficient in coding than MPEG-2.
If no big players like Google/Apple/Microsoft are embracing H.264/HEVC, and making it to be a successful market standard, then I don't see HEVC will soon be widely accepted, and the licensing issue of HEVC may not be quickly solved either.
The history why H.264 license was made to very low or free, was because Microsoft invented VC-1 to be competitor and made H.264 to be at a difficult position. After H.264 becomes cheap or free, it was soon supported by all popular operating systems, Windows, MacOS/iOS and Android.
Because H.265 has no competitor right now, it's hard to see H.265 license issue to be solved soon. so H.265 may be only limited, and use in some 4K or above 4K video only. also H.265 in surveillance market may take a few years to grow to bigger size, that's why H.264+ can be more useful than we thought.
