A city road-works department in Germany is responsible for installing and maintaining traffic lights and street lights. The department houses its raw materials, including lampposts and cable reels, in an outdoor area on its premises. Until a few years ago, there was never any problem with the outdoor storage area. But, as metal prices rose, the department found itself the victim of metal theft, not once, but multiple times. Lockers and barriers set up to protect the materials proved to be an unsuccessful solution as the thieves were quite professional. The city needed a better solution to secure its outdoor storage area.
