With infrared camera detections that can run anywhere from 10% to 50% false positives depending on the scene and environment, the biggest challenge is not buying sensors but trusting what they see. At the same time, many properly calibrated uncooled microbolometers can achieve 1.0 to 1.5 °C temperature measurement uncertainty, and high-performance systems push NETD below 30 mK. This post pulls together the key industry statistics behind performance, contrast, drift, emissivity error, and market momentum so you can separate what is technically achievable from what is actually reliable.
