They are often used for activities like sports, travel, and adventure filming due to their durability and ability to withstand harsh conditions. Many models are waterproof and shockproof, making them ideal for capturing moments during activities like surfing or mountain biking. These cameras typically feature wide-angle lenses to capture expansive scenes and can record in high-definition formats. They often come with various mounting options, allowing users to attach them to helmets, bikes, or even drones.
