Xiaomi Mijia Action Cam Specs

Xiaomi Mijia 4K Action Camera uses a 1/2.5″ 8MP Sony Exmor sensor, IMX317. I think that’s the same sensor used in the recently introduced GitUp F1 4K Action Camera and might be the same sensor used in Sony’s top model: FDR-X3000. As the sensor is a little larger than the commonly used 1/2.3″ action cam sensors, I think it benefits low light recording. On the downside it limits photo capabilities, the max. is 8MP in 16:9 whereas the commonly used 12 MP sensors can do 12 MP in 4:3.

Xiaomi Mijia uses the Ambarella A12 processor, same can be found in many action cameras like SJCAM SJ7, Firefly 8S or Thieye T5. YI 4K Action Camera and GoPro Hero5 use the faster Ambarella A9 processor, furthermore the latest generation Yi 4K+ the Ambarella H2 and SJCAM SJ8 Ambarella H22.

The lens looks quite large in diameter on the pictures, not sure how it will turn out in the real product. It’s an F2,8 7-glass lens with 145° FOV. Field of view is a bit less than for most action cameras (around 170°) which will benefit in fewer distortion images by compromising on the wide angle. It also seems that a UV filter is already built in.

Frame Rates & Resolutions

Xiaomi Frame rate
The following resolutions and frame rates are available (some might be added):

  • 4K – 3840 x 2160p (16:9) – 30 fps (real 4K)
  • 1080p – 1920 x 1080p – max. 100 fps
  • 720p – 1280 x 720p – max. 200 fps

Photo Resolution
Photo Resolution will be 8MP, due to the 8MP sensor, Format is .jpg,it seems that RAW will be available.

Image Stabilization
Xiaomi Mijia Action Camera will feature 6-axis electronic image stabilization. The integrated Bosch BMI160 IMU 3-axis-gyroscope and a 3-axis-accelerometer is combined with a software algorithm to achieve digital image stabilization.


The camera will feature a 2.4″ Touchscreen, which is the largest among action cameras. YI 4K features a 2,19″ touchscreen, whereas GoPro uses a 2″ touchscreen. Similar to YI 4K the camera only shows one button on top and the settings will be done via the screen.

Also, the battery seems to be larger than others. Xiaomi Mijia holds a 1450 mAh exchangeable battery that should last 2 hrs of 4K video recording and up to 3 hrs in 1080p. YI uses a 1400 mAh battery whereas GoPro uses a 1120 mAh battery.

In the video at the bottom you can see that Xiaomi lasts way longer than GoPro Hero5 and also quite a bit longer than YI 4K!
