Camera Cadges from Fluorescent Light

The nature of the mounting mitigates any real ability to perform as “spy cam,” the ring that slips around a fluorescent light bulb to harness the magnetic field generated by the light’s normal operation is powerful enough to power both the camera and the Wi-Fi chip inside. The VGA-resolution camera, made by NEC, can snap images every 10 seconds, beaming them back to a PC.If the ring doesn’t cause any additional power to be drawn in the operation of the lamps—and using my rudimentary grasp of light bulbs I don’t see how it would—then it’s a very clever way to harness cast off electricity, even if it’s only 120 milliwatts.
