What's the difference between a sports camera and an ordinary camera?

1: The sports camera is light and compact, and can be fixed on the helmet and backpack of cars and motorcycles, and separated from both hands.

2. Sports cameras can dive, some are bare-metal waterproof, and some are equipped with diving shells, 30-60 meters deep.

3. Sports cameras mainly shoot videos, while ordinary cameras take more photos. The photos taken by sports cameras are not as good as those taken by mobile phones.

4. The motion camera is simple to operate, fully automatic, and the common camera is complicated to control, but it has complete functions and high photo quality.
