Thermal imaging cameras are generally accurate in detecting heat levels, with typical temperature measurement accuracy ranging from ±2°C to ±5°C or ±2% of the reading, whichever is greater. The accuracy depends on several factors, including the quality of the camera, the calibration, the emissivity of the object being measured, and environmental conditions. High-quality thermal cameras, often used in industrial and scientific applications, offer better accuracy and resolution. These cameras are calibrated to ensure precise temperature readings and can detect minute temperature differences, sometimes as small as 0.05°C. The resolution of the camera, measured in pixels, also affects accuracy; higher resolution cameras provide more detailed images and better temperature differentiation. Emissivity, the efficiency with which an object emits infrared radiation, is crucial for accurate temperature readings. Most cameras allow users to adjust emissivity settings to match the material being measured. Incorrect emissivity settings can lead to significant errors in temperature readings. Environmental factors such as ambient temperature, humidity, and distance from the target can also impact accuracy. For instance, high humidity can absorb infrared radiation, affecting the camera's readings. Similarly, the distance between the camera and the object can influence accuracy, as greater distances may reduce the camera's ability to detect fine temperature differences. In summary, while thermal imaging cameras are reliable tools for detecting heat levels, their accuracy is contingent upon proper calibration, appropriate emissivity settings, and consideration of environmental conditions. For critical applications, it is essential to use high-quality cameras and adhere to best practices to ensure precise temperature measurements.

Yes, thermal imaging cameras can see through smoke to some extent. These cameras detect infrared radiation, which is emitted by objects based on their temperature. Smoke particles are generally not dense enough to block infrared radiation completely, allowing thermal cameras to detect heat signatures through smoke. This capability makes them valuable in firefighting and search and rescue operations, where visibility is often compromised by smoke.
