My third hardware revision of 2016. The theme includes a parallel demonstration of GoPro Hero 4 Silver (1080p, 60FPS, Superview) that costs $ 399.99 to an Eken H9 (1080p, 60FPS, Wide) that costs $ 47 from Sweden or $ 69 from Amazon in the United States.
Actually, this seems to encode better than GoPro. At 1080p @ 60, the GoPro has 4 hours and 22 minutes on a 64GB card. This seems to have 6 hours, 2 minutes and 45 seconds on a 64 GB card. With 1080p @ 30, you'll get 10 hours, 33 minutes and 9 seconds of recording if you use multiple batteries or a $ 29 USB battery pack.
