What is the difference between facial recognition temperature measurement all-in-one machine and infrared thermal imaging temperature measurement equipment?

The temperature measurement principle of both is infrared thermal imaging, but the temperature measurement methods and uses are different.

The facial recognition temperature measurement all-in-one machine has a temperature measurement distance of 0.3-0.6 meters. It measures one person at a time and matches the identity information and photos obtained after facial recognition with the body temperature, which is conducive to data collection and can be used with gates and access control. It can forcibly intercept people who fail face recognition or have abnormal body temperature. They are sensitive to the environment and need to be placed indoors or outdoors in a sheltered place.

The temperature measurement distance of infrared imaging temperature measurement equipment is 5-10 meters, which is suitable for conducting a wide range of body temperature screening for people flow. However, the more densely populated and the more targets are identified, the worse the accuracy will be. The body temperature data is displayed in real time and no data is retained. During actual use, if multiple people with abnormal body temperatures pass through the access control at the same time, multiple people need to be detained at the same time. If there are any omissions, it can only be based on the photos recorded in the background (supported by relevant software) case), conduct troubleshooting manually.
