NEC Camera Powered By Lightbulbs

�

NEC has developed a prototype for a wireless security camera that run off of the power generated by fluorescent light bulbs. The camera just needs to be hung on the ceiling in close proximity to a florescent light source, where it is connected with a wire with a ring-like adapter on the other end.

The flourecent light produces energy through the adapter using electromagnetic induction. The key to the power is not the actual glow, but the magnetic field generated by the AC source in the light. The camera is of VGA resolution, taking shots every 10 seconds and sending the images to a PC through a WiFi connection. — Andrew Dobrow
