Hardware Comparison:


As we have already mentioned that both these cameras possess almost similar kind of specifications so we need to go into deeper details to find design differences. The Yi 4k action cam appears more trendy and sleek with its smooth plastic finish and the attractive rounded corners. Whereas, SJ6 has a rugged appearance with rubberized material that provides textured finish with added grip. You will also find few indicating LEDs on SJ6 body.

Yi Action cam is designed with a 2.19” LCD screen but SJ6 has little smaller up to 2” only. You will find MicroSD and MicroUSB slots on Yi’s body but in case of SJ6, MiniUSB, MicroSD and Micro HDMI make connectivity much easier. Another difference lies in their buttons as Yi 4K has only on button on its body but you will find 3 control buttons on SJ6 Legend.


Second noticeable difference is in accessories of both action cam units. Note that, both of these companies are offering cameras with threaded tripod type hole on bottom side of their body so that users can easily attach them to mounts. But you will find more flexibility with SJ6 as its box includes all necessary mounts that can meet action recording needs with ease. On the other side, Yi 4K box does not even offer a waterproof case to buyers. You have to make all the expenses yourself to fulfill your needs.

The image quality with such interpolated system goes really bad. But if you compare performance of both devices at Full HD 1080p resolution level then you will be able to find impressive quality with Yi cam and it also provides support to 120fps frame rate at 1080p.
