4K resolution video will be the next big technological leap as far as film and television goes. But it doesn't take a massive, expensive camera like the RED Epic to shoot 4K resolution video. In fact, Point Grey's Flea3 webcam—equipped with a Sony Exmor R sensor—is up to the task but is hardly bigger than an inch in any direction.
The technical feat here is that the camera is able to push video to any compatible, USB 3.0-equipped device in real-time—something that requires a fair amount of bandwidth. Obviously, resolution isn't everything, and you probably won't be shooting cinematic masterpieces with this diminutive beast, but if you need a little extra size and clarity from your image, this might do the trick. Though at over £600, the only interested parties might be businesses with video conferencing and surveillance needs. [Point Grey via Engadget]
