DEMA SA was established in 1976. With over 40 years experience in B2B distribution of security equipment we provide technical and commercial support as well as assistance in developing large projects for our customers.

We cover the entire Swiss market, with head offices in Geneva and a branch office in Zug. This allows our clients to discover our showrooms and follow trainings on specific products in French, German or Italian. We supply goods from our stock available in Geneva and our after-sale support has solutions which can be adapted to any situation.


All our activities: intrusion, video surveillance, access control, fire protection and transmission are covered by our specialists who train our professional customers and assist them with installations on site. Our company does not install any of the products we distribute. We do not supply end-customers but only professionals officially registered in the activity of security.


The products sold by DEMA SA correspond to brands of strictly selected manufacturers. Our objective is to offer the best products in their respective field of activity. The constant innovation of our manufacturers partners with whom we are closely working together, allows us contantly to offer the latest developments in technology.
