Thermal imaging cameras in video surveillance systems

The use of thermal imaging cameras is no longer limited to buildings or installations critical to the defense of a country, or scientific applications. Cameras of this kind are employed to monitor unlit areas with dense vegetation, various processes in factories, power plants, oil and gas installations, at airports, etc. The best results can be achieved by creating systems consisting of optical and thermal cameras. This is due to different principles of operation and diverse forms of the generated images. An important part of such systems is image analysis. Thermal imaging cameras used for monitoring purposes usually have essential tools for image analysis, such as motion detection and detection of temperature changes beyond a preset range.
