Whats the function of infrared?
General camera can’t produce a clear image at a dark environment, it just like the eyes of chicken. So, we need something that can help camera to produce a clear image at night. The something just is the Infrared . Infrared can help security cameras work in very little visible light. This can be quite useful if your CCTV application requires your security camera to work in the dark. Infrared light is invisible to the human eye, but to a security camera that is sensitive to this type of light, it may appear to be daylight while remaining dark to the observer.
