Figure 21. Single-person temperature measurement mode The default warning range is 37.3 °C ~ 42 °C. When the highest temperature detected in the center of the screen locates in this range, it will trigger an audible and visual alarm. This mode can be used for accurate temperature measurement in all scenarios, particularly suitable for the fast temperature measurement outdoors at daytime or in environment with complicated thermal radiation sources.
Figure 22. Large-crowd temperature measurement mode Note： The thermal imaging module could not distinguish the properties of the imaging objects at current version. If the lamp box, water cup or metal parts exposed to direct sunlight appear in the screen, the temperature value of these parts may be displayed and the readings will be affected. Therefore, single-user mode is recommended for the complicated environment. 4.4.3.
