Flourescent Spycam

NEC HAVE a wireless camera that can be powered by a fluorescent light. All you need to do is simply attach a ring-shaped component for power acquisition to the bulb. This is a lot more convenient than having to wait for the sun to break through Irish cloudy skies. And since you can run your fluorescent lights all day without drawing anyone's notice, you can also use your spycam around the clock too. The camera uses electromagnetic induction in order to obtain power by using the magnetic field generated by the AC source (45-100kHz) in the fluorescent light. This wireless camera will be operable at 120mW and is capable of automatically adjusting the frequency of shooting video in response to the power supply from the fluorescent light. The camera shoots images every 10 seconds and supports VGA (640 x 480), QVGA (320 x 240) and QQVGA (160 x 120) resolutions. Image transmission is made possible via IEEE802.11b-compliant wireless LAN.
