Sure your mobile phone has video recording capabilities, but can it be submerged underwater...?
Sanyo has a compact camcorder, the DMX-CA100 that not only has a full HD dual camera but it also can be submerged up to a depth of 3 meters.
...the Sanyo DMC-CA100 will have the capacity to record up to 60 minutes of full HD video (1920 x 1080 pixels) MPEG-4 files. Meanwhile, it will also be able to capture plenty of 14-megapixel stills (4640 x 3480 pixels) thanks to its SDXC memory card compatibility. As it’s designed for active use, its continuous shooting feature should prove popular, enabling photographers to capture up to 22 still images at seven frames per second. Additionally, for long-distance shots a “Double Range Zoom” feature will enhance wide-angle capture to telephoto zoom at a magnification level of up to 12x. With this feature in tow, photographers and videographers will be able to alternate between two zoom options. Although there’s no option for optical zoom, its digital zoom focal scope is fairly impressive with a Wide Mode focal range of 40mm to 240mm and a Tele Mode range between 80mm to 480mm.
