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 […]
