Most action cameras are designed to be used in extreme environments, including underwater. Many action cameras come with a waterproof housing that allows them to be submerged in water and protect the camera from damage. The housing can usually withstand depths of up to 30 meters (100 feet) or more, depending on the model.
Action cameras are also built to be rugged and shock-resistant, making them ideal for use in other extreme environments such as snow, sand, and high-altitude environments. Some action cameras even come with additional mounts and accessories that allow them to be attached to helmets, bikes, cars, and other objects to capture unique angles and perspectives.
