How does an Infrared Illuminator work?
IR catches the heat emitted by the body and helps to see in the dark with the help of IR devices equipped with a camera or IR illuminators. IR illuminator are the devices which able us to view in the dark. For more visit – http://www.axtontech.com/
In situations where events need to be monitored at night, black and white cameras are used with infrared illuminators. Infrared light is used because black and white CCD cameras have very good sensitivity in and near the infrared region. These are wavelengths longer than 7000nm (nanometers). The human eye can see up to 700nm wavelength, and anything above 700nm is invisible to the human eye. Most infrared illuminators come in 730nm, 830nm, and 950nm wavelengths. These infrared illuminators are invisible to the human eye, and that’s why they’re perfect for night monitoring. You will be able to see in total darkness with these infrared illuminators, without anyone knowing.
