What's the difference between infrared thermal imaging thermometer and face recognition thermometer?

If you want to compare, you must first understand the principle. At present, the commonly used infrared temperature measurement methods are similar in principle, all based on the fact that objects above absolute zero will radiate infrared energy. If there is energy, there will be a wavelength, and if there is energy, it can be captured, and then the energy can be calculated through a specific photoelectric conversion device. This is the basic principle of infrared temperature measurement. In practice, the common technologies are thermopile and resistance micro-measurement of radiation, thermopile technology is the most common, and the ear temperature and forehead temperature are basically the same, including facial temperature measurement. When I say facial temperature measurement, I actually mean facial temperature measurement equipment.

The principle of the temperature measurement module of the two devices is the same, and the human body temperature is determined by detecting the infrared thermal radiation emitted by the human body. But the difference between them is that infrared thermal imaging temperature measuring equipment can measure the body temperature of many people at the same time, with a wide temperature measuring range, and the intensity of ambient light will have a great influence on the test results. If the accuracy of temperature measurement results is required, it is necessary to install blackbody calibration, so it can only be installed in an indoor closed environment. Moreover, infrared thermal imaging equipment needs multiple devices to complete the temperature detection, so once installed, it cannot be moved at will. So the cost is higher.

Face recognition temperature measuring equipment can complete human detection while brushing face, and only detect face temperature, which reduces the number of temperature measuring points, has relatively low environmental requirements, and has higher stability and accuracy. It can measure temperature in cool and windproof places indoors or outdoors. The size of the face recognition temperature measuring device is only 8 inches. You can move the equipment as needed, and you can also use the charging treasure to complete the temperature measurement work without a fixed power supply. Only one device is needed to complete face recognition, body temperature detection and voice broadcast of test results, and personal body temperature data is automatically saved to the background. The whole temperature measurement process does not need the cooperation of technicians, as long as a security guard is on the side to supervise. Compared with infrared thermal imaging temperature measuring equipment, it also has great advantages in price.

Of course, as far as the current use is concerned, both face recognition temperature measuring equipment and thermal imaging temperature measuring equipment can play a very good role in the temperature measuring process required by the epidemic. The face recognition temperature measuring equipment with health code recognition even won the title of "digital sentry". It can be seen that technology can really have a positive and effective impact on people's lives, and our wisdom in Hanma will continue to work hard to provide you with better and more convenient products. Finally, I sincerely wish the epidemic will end as soon as possible and let everyone feel the wind of freedom freely.
