Integrated two lens of visible light and thermal imagery, the dual-light camera can output visible light and thermal imagery videos simultaneously. Among which, the thermal imagery len supports measuring temperature of focus point, highest temperature point tracking, with accuracy of temperature measuring within ±2%. Infrared imagery and video processing software will go on the analysis and process of the infrared images and video gathered by thermal infrared imager. It can realize the image’s point, line, and frame temperature analysis and generates a analysis report. It is widely used in such areas as forest fire prevention, search and rescue, border patrol, Earthquake relief and do on.
