The Nano 3 has a 1/3'' 800TVL high-resolution sensor which is over 30% bigger than the sensors commonly used in other whoop cameras on the market. That means bigger pixel units, lower distortion and better image quality.
The Nano 3 has an ultra-small high-resolution lens with a FOV that reaches to 160°. Although the lens is incredibly tiny, it performs well on distortion correction. Even with this huge image sensor, the camera still weighs in at just 1.1g (without the cable) thanks to that tiny lens.
