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 .

** **** *** ***** *ecord * *****, you can now record * *****...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 ..
