Novatek is a very popular platform. It's not my field of expertise but as I understand it their SDK is easy to work with including 'defaults' which make developing a good camera easy, so many cams using the 96663 processor will be very similar. Quite the norm in China to 'borrow' design ideas from successful products, so cases and PCB layouts can be very similar too. Rebranding (badge engineering) is very common with all Chinese electronics.
My thoughts are that if you want an Aukey (or any particular brand) it's something of a gamble to buy a similar cam. The 'clone' might be a lesser build quality or have a low-quality lens or be made with cheaper ancillary components. Then again you might get a great cam fully equal to the original- I've had that kind of luck once. I hope someone with more direct knowledge of this cam chimes in here for you but getting specific info (especially on newer products) may not be easy as few people outside of China know which factory builds what cam, and what is inside of it.
