Abstract

The invention provides a system and process in which more than only one category of information must be made available in an optically simultaneously recognizable form to a person in a portable system (17) for protecting and/or guiding persons in dangerous situations, firefighters or rescue teams in buildings. The system includes an infrared camera (12) for recording data, especially heat image data; an energy supply device, especially a battery; at least one interface (18) for transmitting data; and at least one display device (16), especially a monitor and/or a warning light, for visually displaying data. At least one exit finder (13) and/or at least one gas sensor (14) and/or at least one motion detector is also provided. The data determined by the at least one exit finder (13) and/or by the at least one gas sensor (14) and/or by the at least one motion detector and the heat image data of the infrared camera (12) can be displayed on the display of the at least one display device (16) such that the visually displayed data and visually displayed heat image data are visible by the person within a field of vision.
