1. An image-capturing device, comprising:
- a housing having at least one part;
a camera accommodated in said housing for continuous image capturing and a generation of corresponding image data, said camera is a thermal-imaging camera for capturing thermal images;
said at least one part of said housing one of lying in a field of view of said thermal-imaging camera or is embodied as an optical lens and constructed at least substantially transparent in an infrared range and nontransparent in an optically visible range; and
said thermal imaging camera containing a sensor selected from the group consisting of a thermopile thermal-imaging sensor and a micro bolometer thermal-imaging sensor with a resolving power such that a person is captured when the image-capturing device is mounted correctly on a ceiling, and said sensor having a maximum resolution in a range of from 1 to 20 cm.

Abstract
An image-capturing device contains a housing and a camera accommodated in the housing in particular for continuous image capturing and the generation of corresponding image data. Accordingly, the camera is a thermal-imaging camera for capturing thermal images. At least one part of the housing lying in the field of view of the thermal-imaging camera or a part of the housing embodied as an optical lens is constructed such that the part is at least substantially transparent in the infrared range and nontransparent, in particular opaque, in the optically visible range. According to one particular embodiment, the image-capturing device is configured as a person-counting mechanism.
