It's meant to compete with the dominant webcam, the Logitech C920, which does 1080p at 30fps. These are webcams. The Razer costs $150. There isn't a single $150 4k/60fps camera on the market.
Also, we are all ever so impressed by your bandwidth, but uncompressed 4k 60fps video is nearly 711MB (big B) per second. Don't think you've got that kinda bandwidth upstream. Even lossy compressed 4k 60fps video is yuge, and if you are doing that much compression, why are you even shooting in 4k/60... in fact why are you streaming at 4k/60 on a webcam anyway?
According to Netflix, I need to have 25Mbps to stream 4k movies. Assuming that's 25 fps, 60 fps would need 60Mbps. Now, video chat is much more compressible than movies (because the picture does not change much), so in reality I would need much less than 60Mbps for 4k@60 video chat. And guess what? I just did my internet bandwidth test: 391Mbps down, 124Mbps up. So yeah, I got plenty for 4k@60 stream.
Your behavior is of an insecure 14-yr-old. I say this to inform you, not to deride you. I suggest you observe better manners.
With that said, your comment expresses an incomplete understanding of video technology. Netflix uses well-tuned, precompressed HEVC video for 4K. No PC can encode HEVC in realtime in high quality at low bandwidth. Even a 10-core Broadwell-E cannot realtime encode with settings that would give you good quality at their bit rates, so a webcam, with its limited hardware, would of course have a much harder time.
Now it is entirely possible to stream realtime 4K at fairly poor quality but low bitrates using dedicated encoding hardware, but such hardware is expensive and not in high demand. Why would 4K matter on a webcam -- a device usually used to check when the kids get home, verify the hours claimed by the cleaning crew, or record burglaries?
So that p1esk can "zoom and enhance" to 1024x magnification on the burglar's license plate, and then keep zooming and enhancing so he can read the dna pairs on the burglar that's escaped.
In all fairness, broadcast and "broadcast" are different beasts compared to point to point communications. While someone like Netflix can afford to use the very best encoder implementations out there, they have to encode one or a few streams offline for a million customers. This means that the stream must be resilient against poor network and poor customer capabilities. Customers must be able to fastforward in the video.
A web camera working in a point to point scenario will have to worry about encoder cost. But unlike netflix, they only need to worry about a single, linear user. And the encoder can adjust to network conditions on the fly.
Finally, the progress of video coding standards is such that by simply going for the next-newest standard, processing cost and chip availability is significantly improved, while bitrate required for a given quality may increase by, say, 2x.
While a web cam can be used for surveilance, that is hardly the only usage. Nor the main usage in my view.
No 4K/60fps yet, but we are getting close; Action Cams such as the Xiaomi Yi 2 do 4K/30fps and 1080p/120fps and are $250 right now. With a capture card, particularly if it supports it is possible to use action cams (with A/V out) as "webcams", assuming the capture card has "DirectShow" drivers, which allows it to be selectable as a video-in source in programs such as Skype, like other USB webcams.
They sure activated my hilarity unit with pimping the "no green screen needed background removal through intel's AMAZING realsense technology" BS while showing off the practically pathetic and laughable results. Seems like "realsense" will be even more unimpressive than I anticipated. More like "real non-sense". Not only does it ALMOST manage to remove the background, but it also manages to remove the actual person, but as a compensation, leaves behind fugly artifacts.

What the hell is this? 1080@30? How about 4k@60? Or at least gimme 1080@120. And yes, I do have the necessary bandwidth.Cygni - Friday, September 2, 2016 - link

Worse yet, Realsense cameras require gen-6 core processor. Haswell-E even need not apply.BrolY_LT - Thursday, September 8, 2016 - link
where to get the camera to 4k 60fps on Skype to function and aplmai play on PC NORML ?
