I wish people would understand that a bigger number does not necessarily means better... H.265, 30Mpx... people see bigger numbers and always assume it is better...

Patent Issues
H.265 is cited as having "a much higher patent cost", though no specifics are given. While these patent costs are not directly seen by the end-user, they are seen in the form of increased product cost.
ha since when have the chinese cared about patent laws. they copy, what ever is sent over there and manufacture it under a new name and when legal problems arise the dissolve and start another new one under a different name.
I will say h265 will have to have some serious horsepower to decode for VMS's or live viewing for that reason alone it wont take very well

Too often our industry jumps the gun on new technology and launches it into the market prematurely. I prefer refinements in existing technology to create a great product, than creating new products that might not work much better. We are using Hikvisions H.264+ with Hikvision recorders and DW Spectrum and have seen great results. This is a smart move IMO.

That statement is either pure hyperbole or pure idiocy, take your pick.
Because regardless of how much better h.264+ is than h.265, they are both trying to solve the same fundamental problem, namely more efficient compression.
Moreover, they're not exclusionary technologies. Even the uber-cautious Axis sees smart codecs and h.265 as complimentary technologies, as indicated here:

Gotta give credit to Hik on calling their own bad bet. Looking at the Chinese site one might not realize the contempt they have for h.265, as a third or more of the network cameras listed are h.265 and get top billing:

Keep in mind H265 first usage won't be for CCTV solutions.... Mass market industry needsmore efficient compressors to bring larger streams to our large 4K TV sets in our homes... No Smart Codec in TV because, to display Avatar from J Cameron it's realy very very bandwidth consuming in IPTV - no still pixels. 4K , 30MP...and more cameras located in very complex and moving areas will also need something better . So now H265 isn't mature, too new.. ok, like the High H264 profile in a camera, which improves H264 quality but put the mess in term of CPU in your server
But be sure it's what we will find soon in our set-top box iand that day, the CCTV cameras will obsviously take advantage of this codec when the costs end efficiency is more realistic. When our Telecom & Internet providers will disptach larger streams to larger TV sets is one of the key points of upcoming years , this will decide if the technology is mature and cost effective or not (so might be in 2018 instead of 2016 or 2017..)
Usually now, Mass market industry adopts new technologies firts, and security follows (remember H264, EIS, WDR, face detect, or Cmos) Right now Security is back ahead with H265 which isn't realistic. A too small market can't decide by it self ...so wait & see...
Back to H265 it is also working with smart codec ... if you spare naturally 30%.... when combined with Smartcodec and Dgop (so H265+) you can reach 30% savings vs H264+
So when you could record 3 weeks, you can now record 4 weeks...and keep H265 only for records and H264 streams for display to save CPU. How much does it cost you to choose right now a H265+/H264+ camera instead of a H264+ camera to prepare the future and eventually migrate later to a full H265 solution is the question ..
The other question is also , with current H265 NVRs, do we save 30% of the storage and for which additionnal costs in the NVR? John; this could be tested once

So what's wrong with combining smartcodecs with H265.....? [Rhetorical]

Then again, it might get more than 100% savings, like in this actual test of a Hikvision h.265 surveillance camera. Which, by the way, this camera continues to do in a real, if somewhat unchallenging courtyard scene, largely devoid of moving fans.
Which makes you wonder why a company like Hik, who would easily make a statement like "May improve bitrate by 100%", if it could be be justified at all, would transform it into the logically compatible but far bleaker "May NOT improve bitrate by 100%".
Because they're just that dang gone honest?
