SJCAM SJ4000 Air Overview The SJ4000 Air is one of SJCAM's budget action cameras that still delivers QHD+ (close to 4K) video and 16MP photos. Doing away with image stabilization, a touchscreen, and native waterproof capability, the SJ4000 Air focuses on image quality and affordability. Although not waterproof out of the box, it comes with a 98' waterproof housing, which is also used to attach the camera to one of the several mounts included, such as the helmet mount.
