There's hope, since
iPhone 6 has H.265 already.
Some Dahua NVR's have H.265 already.
Can you stream a Dahua NVR to an iPhone via H.265?
Exactly how Apple is implementing H.265 is unknown at this time, but considering the feature is restricted to the iPhone 6 and iPhone 6 Plus, some speculate the new A8 SoC incorporates a specialized encoder/decoder module not present in older handsets.
Today, (actually yesterday), must be your lucky day:
Hot off the press... Now I have to get one of them 4K NVRs...
For H.265, we will all know more in a few weeks after the Spring new product announcements are made. I suspect there to be some well-known manufacturers embracing H.265.
That said, I am skeptical about bandwidth savings. Even within H.264, there are lots of differences in bandwidth consumption even when the obvious things are controlled (resolution, frame rate, compression). For example, see: IP Camera Bandwidth / Storage Shootout
Also, Axis is now positioning its Zipstream as delivering just as much savings as H.265 but within H.264. We will have test results of that by end of April.
Hikvision presented its first equipments with H.265 compression at recent ISC Brazil:
Probably they will be showing that at ISC Las Vegas too.
This is a case where the fragmentation and "open" nature of the surveillance market is working against us. Given the need to decode (or transcode) H265 and its increased CPU requirements, we'll be the last industry to fully realize its benefits.
Drivers will be transmission bandwidth--although customers don't care about this directly--it needs to be explained to them, and storage, which customers find more directly compelling. But in the storage case they can get a bigger disk with lesser expense than new cameras AND new clients.
It will be great to have new H265 products on the market, but they'll need to be available at all price points and will not saturate the market for at least an obsolescence cycle or two.
