Bisou is an illumination and sound device with an innovative approach to lighting up residential areas and delivering penetrative audio media. A Bisou unit consists of a security lamp (with motion sensor) attached to speakers and connected to an electricity pole or another supportive structure from where it can plug into an electricity grid. The lights only come on when motion is detected and it is accompanied by audio media which could be a short piece of music, news, public announcement, advertisement, etc. This project was developed due to a considerable amount of crime occurring in areas that were poorly lit. The town council apparently does not have the resources to light up the entire municipality (particularly the suburbs) and thus a self-sustainable development project is necessary to deal with the problem.
