Radiation intensity: The radiation intensity of the 850nm Infrared LED is about two to three times higher than that of the 940nm IR light.
The human eye can see the light wavelengths in the range of about 380nm to 700nm. Light above 700nm in the infrared spectrum (IR Light) is not visible to the human eye. The shorter “near-infrared” wavelengths, which are closer to visible light, from about 700nm to 900nm, can appear as a faint red glow when looking directly at a high powered IR LED source. However, it is invisible to human eye as “light” that illuminates other objects.
Are all cameras IR compatible/sensitive to IR light?
Answer: Only the true Day/Night cameras using a physically removable IR cut filter perform well with IR illuminators.
