A method for performing a checking of a person, by infrared light, comprising:
- determining a distance between a source of infrared radiation and the person by way of light according to a distance definition, wherein the intensity of the infrared radiation is set in dependence on the distance as determined.
A device for performing a checking of a person, comprising:
- an infrared source, a light source situated at the infrared source, an optical camera, and a controller, wherein the controller is configured to illuminate the light source on the person, wherein the controller is configured to determine the distance of the person from the infrared source according to a distance definition based on a picture taken by a camera, and wherein the controller is configured to establish the electric power of the infrared source and/or the radiation intensity put out by the infrared source based on the distance.
