One of urgent security problems is a detection of objects hidden on a human body. Obviously, for safety reasons, X-rays cannot be used for such object detection widely and often. For this purpose, the passive THz camera is used with high efficiency. However, IR camera is much cheaper in comparison with the passive THz camera cost. Therefore, using the IR camera for the detection of objects hidden on the human body under clothes is more preferable. We examine applicability for this aim the IR camera, produced by FLIR Company. For increasing of image quality we propose changing the temperature mode in a room where the detection of an object is provided. Using the temperature contrast between various rooms, in which sequentially a person is, one can essentially enhance the observability of an object hidden under clothes during about 5 minutes time interval, at least. We show that it is possible to see banknote (and other objects) concealed on the human body. It means enhancing many times of temperature resolution of IR camera.
