This is the camera that mounts to a helmet and captures video in two directions simultaneously, displaying footage in a split screen. Mounting to any ATC-compatible helmet, the camera's twin lenses record in opposite directions and each swivels 180° manually for the desired angle (one tilts up/down while the other pans left/right) each providing a 110° field of view while cycling, canoeing, or skiing. A sliding bar pushed with the thumb or forefinger records video without the need to fumble for a button or take one's eyes off course. With built-in auto-exposure and white balance that provide high-quality footage, both cameras capture 720p resolution high-definition video at 30 fps when the vertical split screen option is chosen; horizontal split screen option records at 640x480 VGA resolution. Video is stored onto a microSD card (required); supports up to 32GB microSD cards. It connects to a computer with the included microUSB cable for downloading video or charging; its lithium-ion battery provides up to two hours of operation from a two-hour charge. 4 1/2" L x 1 1/2" W x 1 3/4" D.
