[0002] At present, common flame detection devices include visible light cameras or infrared thermal imagers, which have their own advantages and disadvantages in actual use. In order to improve the accuracy of fire source detection and timely discover and prevent fires, some inventors have combined visible light imaging and infrared thermal imaging technology to design a fire source point detection device that combines infrared light and visible light. However, after the combination of the two, the structure and circuit of the equipment are complicated, which is not convenient for maintenance and repair. Once there is a problem with the components inside, it needs to be disassembled for inspection or replaced, which increases the difficulty and cost of maintenance.

[0003] In addition, when the existing fire source detection devices are used for fire source detection in places such as buildings or warehouses, the space in the above-mentioned places is relatively complex, with many corners and hidden spots.
