Thermal cameras are useful devices, Today, advanced thermal imaging devices with high sensitivity are being developed and used, especially in the medical field (Lahiri et al., 2012). Products from the research results of the author group towards compact size, easy to handle, convenient to carry, low cost of implementation, monitoring range in the measuring area of the sensor eye up to 7 meters, the monitoring temperature zone can be limited, the color displayed is equivalent to the temperature zone, and the resolution of the thermal pixels can also be adjusted simply through the buttons. In order to expand the application range of research products, improve accuracy, reliability, increase resolution, etc., it is possible to use more measuring sensor eyes, use wireless communication networks, accurate image recognition and processing algorithms, large display screen to facilitate monitoring more clearly.
