The TP-Link Quarter Camera is a wearable digital video camera the size of a quarter (an American 25 cent coin). It is operated through a mobile charging base that features an interactive display and a memory card slot. The cylindrical camera can be removed from its base and used as is, or with one of three sophisticated attachment solutions: a suction cup to mount on stationary objects, a magnetic system for thicker materials, or a spring steel clip to attach to clothing.
