The new wireless camera developed by NEC can be powered by a fluorescent light. Having it attached close to a fluorescent light, you just need to connect a ring-shaped component to the fluorescent light to take power from the bulb. Its way of taking power from the bulb is by means of electromagnetic induction generated by the AC source (45-100kHz) in the fluorescent light. It’s kind of convenient for super stores or offices, which you need no additional power for this camera, as long as you keep the fluorescent lights on your ceiling on.
But the only inconvenience is during night time that you wanna have this camera to monitor your office or store environment, you’ll need to keep the lights on as well. But think further, if all those lights are off, the camera would mostly fail to capture anything for you as the environment is completely in darkness. So, you’ll need to keep one or a few fluorescent lights on, if you’re interested in any movement in your office space or store during late night.
The camera has the built-in intelligence to adjust its shooting frequency depending on the power it absorbs from the lights. It’s operable at a very low power as low as 120mW. The camera is capable of shooting images every 10 seconds and supports VGA (640 x 480), QVGA (320 x 240) and QQVGA (160 x 120) resolutions. No words on pricing and availability yet!
