IR technology is currently the best solution for illuminating really dark areas without creating light that is visible to the human eye. The ARM Electronics C520BCDNVFIR is - in addition to its high resolution of 520 lines - equipped with 21 IR LEDs, allowing the camera to produce identifiable images at a distance of up to 49' in the dark. This makes it the ideal camera for securing parking garages, alleyways, backyards, pool areas and similar places containing little or no light.
