I have a Go Pro HD camera that I use for recording things in a car and for a few other purposes. The camera is a waterproof sports camera, but for it to be waterproof it has to be inside a plastic shell. V.I.O. has unveiled new sports camera called the POV.HD that is waterproof and doesn't need a plastic shell to survive the rough world of sports recording.
The camera is up for pre-order right now and it's not cheap at $599.95. The camera records in 1080p HD resolution and can be mounted on helmets, goggles, and in other places. When in 1080p mode the camera has a 142-degree field of view and in 720p 60fps slow motion mode the camera has a 95-degree field of view.
The camera comes with a small control box that allows the viewing of video in the field, which is something the cheaper Go Pro camera lacks. That box has a TI Da Vinci processor inside. The processor allows for automatic lens distortion correction, vignetting correction, and lens softness correction. The camera also has a wireless remote for controlling the functions that can be mounted as well. The cam can survive submersion in 1 meter of water for half an hour and has an environmental rating of IP67. Video is stored to SD cards.
