Thermal imaging can detect a person in 90-100 degree weather, but it is important to note that thermal imaging primarily detects temperature differences. In this temperature range, the human body will typically be warmer than the surrounding environment, allowing thermal cameras to differentiate between the person and the background.
However, it is worth mentioning that thermal imaging alone does not provide a detailed visual representation like a regular camera. Instead, it displays a heat map where warmer objects appear brighter or in different colors depending on the specific color palette used.
Regarding high winds, they can potentially affect thermal imaging to some extent. Wind can cause convective heat transfer, which can alter the temperature readings captured by a thermal camera. Strong gusts of wind can cool the surface of the human body, potentially reducing the temperature difference between the person and the environment, making detection slightly more challenging. However, under normal wind conditions, thermal imaging should still be effective at detecting a person's presence.
It's important to consider that the performance and effectiveness of thermal imaging systems can vary depending on the specific camera model, environmental conditions, and other factors. Consulting the manufacturer's specifications and recommendations for the specific thermal camera being used can provide more detailed information on its capabilities and limitations in different scenarios.
