"If you’re looking for an action camera on a budget,
just to try things out, you can't go wrong with the
Yi Camera"
According to Xiaomi on its official blog, the Yi Action Camera is able to shoot videos at 1080p and 60 frames per second through a 16MP camera that packs the acclaimed Exmor R BSI CMOS image sensor developed by Sony. From these specs alone, the device is already superior to the Hero, which is only able to record 1080p video at 30 fps or 720p video at 60 fps using only a 5MP camera.
With a much cheaper price, Xiaomi's Yi camera is able to deliver matching quality with the GoPro HERO3, although there is an obvious gap between the Yi and the GoPro HERO4.
