Wireless camera powered by fluorescent light
The magic lies in a ring-shaped component attached to the bulb.
Japan's NEC has unveiled a wireless camera that can be powered by something as frugal as fluorescent light, which provides an indoor version of solar power. The magic lies in a ring-shaped component attached to the bulb, which then generates a magnetic field of power.
Tech-On reports that the wireless camera can automatically adjust its video-shooting frequency according to the power supply from the fluorescent light. It can be set to shoot images every 10 seconds and supports VGA (640x480), QVGA (320x240) and QQVGA (160x120) resolutions.
