Beyond basic thermal imaging capabilities, you can find infrared cameras with a wide range of additional features that automate functions, allow voice annotations, enhance resolution, record and stream video of the images, and support analysis and reporting. Since infrared cameras' main function is to detect the heat of an object and not its color, the images are usually displayed as either monochromatic or green. The signal-processing unit sends the information to the display, where it appears as various colors depending on the intensity of the infrared emission. Wireless cameras work by transmitting video and audio through radio waves. Infrared cameras are able to detect infrared energy (or heat) without being in close contact with the subjects. However, infrared light can be felt as heat. However, near-infrared and thermal cameras have very important distinctions, particularly in heat sensitivity. The combination of all the impulses from all of the elements creates the image. And since heat can be transferred, elements like colors, textures, the sky, trees, and even human subjects will reflect and radiate infrared light differently as opposed to visible light. So the electricity cost to run it for 24 hours can be calculated as 1500 x 24 x 0.13 1000 (where division by 1000 is to convert watts to kW and multiplication by .13/kWh is the average American electricity rate). This unique and challenging type of photography involves capturing what our eyes cannot see with the use of specialized camera equipment that can see and record light that is beyond the visible spectrum. An IR camera, also called a thermal imaging camera or a thermal imager, records infrared radiation given off by the objects in its field of view, producing a thermogram (infrared image).
