This is the hands-free, high-definition video camera that captures the action while you snowboard, scuba, sail, or cycle. The camera can be mounted to a helmet, handlebars, seat post, or snorkel–just about anyplace–using the included mounting hardware; its waterproof housing allows you to capture underwater action down to 180′. It can capture video (as well as audio) in 1080p high-definition resolution with its 127º wide-angle lens (170º for 960p and 720p resolutions), saving content as an MP4 digital file onto an SD card (sold below). At 1080p resolution, a 16 GB SD card can store up to 2 1/2 hours of video (it can support 32 GB SD cards). Videos are downloaded to a Mac or a PC running Windows 7, Vista, or XP using the included USB cable.
