Sports camera is getting more and more popular, as a necessary partner for out-door sports, such as skiing, skating, riding, surfing, diving and so on.
Action cameras are unlike any other kind of camera. They're designed to be attached to helmets, surfboards, cars and other objects, and they're small, tough and simple, with a lens that captures the world in high-definition video in a wide-angle fish-eye perspective.
Their small size and dramatic POV ('point of view') footage has made them popular with extreme sports personalities who capture their adventures by attaching cameras to themselves or their equipment. They're also used by TV production companies where using a regular video camera would be impossible.
Action cams are almost the opposite of regular video cameras – they're small, they're inexpensive, they're simple to operate and tough.
GoPro is the market leader with its iconic box-shaped Hero cameras, but action cams also come in a 'bullet' style, like the iON Air Pro. There's lots of choice now, and you shouldn't just buy on brand – think about what you want from an action camera and how you plan to use it.
