Yi 4K

Ever since the original Yi action camera became a great success in 2015 it was clear that Xiaomi will make a successor. Now the wait is over. It took a little more than one year and in May 2016 the new Yi was launched in China. Named as “Yi 2”,  also know as  “Yi4K” this camera records video up to the 4K resolution. The latest Ambarella chipset and a big upgrade in usability make the new model a worthy competitor on the market.

The first Yi was known to be a great value for an good action camera. The new model includes more features and a LCD touch screen which sets it apart as a more premium option. Both models co-exist – the relatively simple Yi and the advanced Yi4K at a higher price point with still great value.
