What are the advantages of infrared lights?

Although the IR light is invisible to the human eye, the IR LED’s will produce a faint red glow when looking directly at the camera or source. The main advantage of the 940nm wavelength is that the IR LED’s do not produce any visible glow.

Are security cameras sensitive to 850nm?

In other words, if the illuminator is 850nm, your security camera must be sensitive to that wavelength. Most cameras are sensitive to 850nm. Security Cameras that are 940nm are available as well, but much less common.

850nm vs. 940nm, IR Wavelength Comparison for CCTV Applications

There are two common IR wavelengths used in CCTV applications today. IR or Infrared wavelengths are measured in ‘nm’ or nanometers, which are used to specify the wavelength of electromagnetic radiation near the visible part of the light spectrum. Visible light ranges from about 390 to 700nm. The IR in CCTV applications take over from there, commonly 850nm and 940nm, which allow us to see images that would normally fall outside of our visible range, thus IR Illuminator. These IR LED’s are used to produce, or improve ‘Night Vision’ capabilities for security cameras

850NM LED WAVELENTG

Although the IR wavelengths 850nm and 940nm, respectively, are fairly similar in performance, there are a few important differences worth noting. The use of IR LED’s in security cameras has become commonplace as technology has improved dramatically and cost has come down. Generally, the great majority of security cameras or CCTV Cameras are sensitive to the 850nm wavelength. Although the IR light is invisible to the human eye, the IR LED’s will produce a faint red glow when looking directly at the camera or source.

The main advantage of the 940nm wavelength is that the IR LED’s do not produce any visible glow. In other words, they are completely invisible and can be used in applications that are required to be more covert. In fact, many people refer to them as ‘Covert IR’. This type of IR is also useful in places where a red glow may be mistaken as a signal and can not be used. The disadvantage of 940nm is that they are about 30-40% less effective and will illuminate less distance.
