Unitraffic AB supplies video systems to the Nordic police amongst other things. These video systems get assembled into cars and often have client-specific requirements regarding usability and functionality. In order to satisfy these demands, a unit that could control all of the systems incoming components was needed and that’s why Weltgeist was hired to develop both hardware and software. To communicate with the camera, the digital video recorder and other electronic parts the unit has a micro controller that does just that. The interface is an OLED display (a display with high contrast and readability) and a couple of buttons.

The project comprised of coming up with a prototype, hardware construction (circuit diagram, PCB design, CAD/CAM) and firmware development for the application run on the micro controller.
