As its name implies, the ATC Chameleon has been inspired by the chameleon – a creature that can see both forwards and backwards at the same time. The camera has two built-in, 170-degree adjustable lenses. These allow users to capture two high-definition videos from different angles simultaneously and in sync, and to later play them back in split-screen format. The camera operates for up to two hours on a re-chargeable battery. Other features include a built-in microphone and speaker, and a micro SD card slot that supports up to 32GB of memory. With a variety of mountings and an optional waterproof case, the camera can be used during a wide range of activities from running a marathon to walking down the aisle at a wedding. It retails for $200 from www.oregonscientific.com
