Thermal imaging cameras

Thermal cameras are different from a “camera”. Although we call them that, in reality this observation system is more like sensors. In order to understand more easily how they work, the principle of an ordinary video camera should be left aside. FLIR takes pictures of heat, not visible light. Heat (also called infrared or thermal energy) and light are both part of the electromagnetic spectrum, but a camera that can detect visible light cannot see thermal energy, and vice versa

Night vision devices (ÖVS/NVD/NVG)

Those “green shots” we see in movies and on TV come from a night vision device (NVG) or other devices that use the same technology. NVGs take in small amounts of visible light, greatly amplify it, and display it back to the user. Cameras made with NVG technology actually have the same limitations as the naked eye: if there isn’t enough visible light, you can’t see well with them (but you can use extra Infrared light picked up by the NVD)

Fusion technology

Fusion combines both of the aforementioned ways of viewing digitally. At this point, the development work through which they are set up is very important – Speed, sharpness, energy efficiency, etc.
