Camera specs are actually a bit better than what's listed, at least it was on the unit I tested: * ~40° hFOV and ~30° vFOV * Range depends on the IR source: I had ~1.5m steady detection for a lighter flame and LEDs, but ~4m with a TV remote. Detection DOES require very precise 'aiming' at the sensor. LEDs need near perfect angles at greater distances. Only trouble I encountered was occasional trouble with the Processing code found on the wiki article. If you can code a bit, try to see if you can force resynchronisation of the serial port. I had to use LabVIEW for a school project and forced closing, reopening and reconfiguration of the port had it working every time on all tested computers. All in all, it's a very fun product for the price. I'd love to know if hacking the camera firmware is in any possible.
