    Xiaomi Yi 4K+ Action Camera

    Yi represents incredible innovations. Make each your day breathtaking with the 4K video format.

    • SONY IMX377 image sensor
    • Ambarella H2 chipset
    • Quad-core ARM®Cortex®-A53
    • 2.2″ touch screen AUO display
    • 4K — incredible video format
    • Dual band 5GHz WiFi

    Your world in 4K/60FPS format

    Professional quality created for you

    YI 4K+ has twice the frame rate of its previous model.

    We used an energy efficient chip of new generation Ambarella H2, a Sony IMX377 matrix and a 7-layer glass lens to provide you the ability to shoot video in the 4K format at 60 fps. Just imagine a fourfold 1080p quality — this is the 4K format, and now it’s available for you.

    Ambarella H2 master chip

    • the first 14nm video processing/encoding SOC
    • high-performance
    • low power consumption

    A new high-performance and energy-saving the newest Ambarella H2 SOC is the heart of Yi 4K. To create the camera which is so powerful and compact at the same time, we have used a cutting-edge 14 nm CMOS technology. The H2 SoC model is more suitable for high-end cameras with support for 4K Ultra HD H.265 / HEVC video with a frame rate of 60 fps and 4K. The advantages of H2 include 10-bit data representation, which provides a wide dynamic range (HDR).

    Higher speed and reduced energy costs became possible through the use of quad-core ARM®Cortex®-A53 64-bit processor and a high-performance DSP. Н.264 ВР / МР / НР encoding delivers a high-quality video recording at a lower bitrate, increasing the allowable recording time, even if you shoot in 4K / 60fps.

    • Н.264 video encoding
    • 14 nm CMOS
    • 3D noise reduction
    • 800 MHz quad-core CPU

    Eyes like a hawk
    7-layer glass lens

    Yi 4K Action Camera is equipped with a 7-layer optical glass lens, which in combination with a wide aperture of f / 2.8 and 155° FOV increases the amount of light absorbed, so you can shoot live and detailed footages.

    Combining of Gorilla Glass and Retina Touch Screen
    Perfect LCD screen

    The bright, large and highly responsive 2.2″ retina touch screen gives you a convenient, intuitive and fast control, preview and playback experience.

    This custom design combines a high-sensitivity 330 ppi Retina Touch Screen sensor technology for easy and simple operation and a Gorilla Glass, which is able to protect the screen from scratches and bumps. The display viewing angle reaches 160 ° without distortions, the resolution is 640 × 360. With the optimal screen ratio of 16: 9, you can quickly and easily adjust the desired frame and make the perfect shot. Manage your Yi 4K action camera using only your fingertips. You no longer need a lot of additional devices.

    • 2.2 ″ touch screen
    • 16: 9 aspect ratio
    • 640 × 360 resolution
    • 160 ° viewing angle

    Longer video shooting with Yi 4K

    When developing the new Yi 4K action camera we were thinking of photographers and travelers. We have used the world’s leading Lithium Ion Battery with Energy Content 5.39 Watt Hours and a high voltage of 3.85 Volts. Thus, the Yi 4K action camera weights only 27.1 grams, and in the table below you can see the approximate continuous recording time you can expect when shooting in various video modes using a fully charged battery:


    Connect. Discover. Edit. Share.
    There is no more need to wait with high-speed dual-band WiFi from Broadcom

    Broadcom, the leading provider of innovative telecommunication solutions, has created a BCM43340 chip, which operating speed will not give you time even to blink. Support for 802.11 a / b / g / n 5 GHz WiFi transmission increases the electromagnetic penetration and creates the effect of anti-interference, which is an additional improvement to the 2.4 GHz transmission. Download speed up to 30 Mbps, more time to shoot, edit, and share stunning videos.

    Shoot, mount and share videos as a professional with Yi Action APP

    6–30 seconds for video editing, colorful filters, and sound design. Even if you are a beginner, you can work as a professional. You’ll never want to go back to the PC.

    Join the discoveries, join the world

    Share your life with the world Yi fans community

    Shoot, create and even share your epic videos with a global Yi community. Explore fun, creative and innovative ways to shoot with Yi. And even if you just want to view photos and videos of other users you should join the Yi community in social networks.
