Is it possible to get hit in the face when someone steals a video from under his ass while squatting in the toilet?

This question is very strange. If the camera is not blocked or the recorded person has good eyesight, he can recognize the location of the invisible camera. Only from the perspective of photographic optics, it is demonstrated that if the candid camera angle does not overlap with the face angle of the subject, the subject's face will not be photographed. Generally speaking, there is no risk of showing your face if you can't see the camera with your eyes (excluding the case where the recorded person doesn't pay attention or can't identify the camera).
