Nowadays, in many Italian and European universities, teachers' training includes one or more examinations related to new didactic methodologies and practices. The topic of this paper is how it is possible to realize a new video analysis laboratory as a didactic and research "tool" for teachers' training at the University of Salerno that can support teaching-learning process for new teachers. The main idea of this project is to design and implement a mobile video analysis laboratory for video recording real or simulated didactic activities. In addition, the concept that drives this research is to develop a "plug-and-play" laboratory that can be installed everywhere in less than 15 minutes by everybody. This laboratory is already designed and tested and is composed of five cameras, a control room software and an open source video analysis software.
