I need a camera that can capture infrared light. Is there a cheap solution?
Most low-cost video cameras have a certain response to infrared, and those used in even greater surveillance, as they can see people and objects illuminated with infrared LEDs. However, it must be remembered that the infrared spectrum is broad. Thus, for the so-called near infrared whose wavelength approaches the limit of our vision, it is easier to obtain a common surveillance camera that detects it, which does not happen if the infrared is in the range away from the spectrum, out of reach of the sensors.
