Concealed weapon detection (CWD) is an important part of everyday law enforcement. There are numerous facilities that are endangered of an terrorist or an fanatic individual attack. Commercially used weapon detection gates are very expensive and sometimes impossible to install into already existing security infrastructures. Here we present a miniature prototype device for concealed weapon detection using two cameras: IR and visual. The prototype consists of two printed circuit boards (PCB). First PCB is responsible for analog to digital and digital to analog conversions of the video stream. The second board is the main processing unit realizing the presented fast image fusion algorithm. The relative size of the prototype can be assumed as a miniature in comparison to the current used solutions. Such miniature device could be mounted under the ceiling or inside 3 DOF gimbals for wider view angle. Presented device can be considered as an alternative to already existing man-sized gates traditionally used for CWD.
