Sodi Costruzioni Elettromeccaniche – as it was originally named – was established in 1964 by Fiorello and Carla Sodi in a small workshop in Florence. At first the company specialized in technical design but soon began manufacturing electro-diagnostic equipment followed by environmental safety products and electronic systems for monitoring road traffic.
The Traffic Division is well-known for its Autovelox Speed Enforcement Device, which is synonymous with speed enforcement nationwide as it entered the Italian lexicon, and other law enforcement instrumentations. The Environment Division produces instruments - less known to the general public, but equally effective - for water treatment.
