Abstract

A thermal imaging camera includes a fastening device, which is configured to be mechanically coupled with a fastening element of protective clothing of a user, to detachably fasten the thermal imaging camera to the protective clothing. The thermal imaging camera further includes a first interface as well as a second interface, which are each configured to output data of a thermal image. The thermal imaging camera further includes a control circuit, which is configured to detect a mechanical coupling of the second interface with a third interface of a display device and to output the data of the thermal image exclusively via the second interface as a result of the detection of the mechanical coupling. The control circuit is further configured to output the data of the thermal image via the first interface when the second interface is not coupled mechanically with the third interface.
