The FireWatch optical sensor incorporates enhanced spectral sensitivity with near-infrared (NIR) sensing capabilities. This permits detection across a wide range of visible light wavelength (480 to 1200nm) day or night—far superior to that of the human eye/CCTV which has a range of only 400 to 750nm. Furthermore, the sensor’s extremely high grey-scale resolution enables it to distinguish between over 16,000 shades of grey.
