Is it really 4K? The SJ9000 Wifi "4K" Sports Ultra HD DV 30M Action Cam Unboxing vs Campark V30

Banggood offers an Action Cam that boasts 4K quality at a bargain price, but does it live up to the hype? I unbox the SJ9000 (not affiliated with SJCAM), try it out both indoors on a tripod and outdoors handheld, and compare it to my Campark V30 in a side-by-side test of the footage.
This SJ9000 is NOT a sponsored product. I purchased it from Banggood for the sole purpose of this KZbin unboxing and review. It was on sale when I placed the order, so the price has likely changed, but here is the product page for this item:

The Campark V30 that I used for comparison is available from Amazon.
