CHAPTER 5 Thermal cameras
Thermal network cameras create images based on the principles of infrared (IR) radiation. All objects and organisms generate some amount of heat. Heat is a form of light that is invisible to the eye and is also known as thermal IR radiation. The thermal camera serves as a heat sensor that detects temperature differences between objects and the scene itself. Rather than a picture of light, the thermal image is a visual capture of heat. The more heat an object emits, the brighter it appears in a thermal image.
