Technologies

thermal_1
thermal_2

Thermal camera (Thermal)

Enables image recording in the medium and long infrared bands

Thermal imaging cameras capture images based on measured thermal radiation emissions. This allows them to detect objects even in complete darkness and monitor them for temperature anomalies. Industrial versions also enable temperature measurement, which is particularly useful for monitoring production processes and detecting fires.
