Portable video camera. Small in size. Durable. Water resistant. And just like typical digital recorders and camera, the video screen is meant to view on the fly. For proper viewing you'd download content onto the device of your choice. And for all intents and purposes, the nature of it's build make it the preferred option when recording without having to worry about about it breaking or getting damaged in any way.
We've used ours while out at the beach in the water, at the Dells and on boat rides. Dropped it a sh*t ton of times too. Still working.
