Hysos

Hysos is an independent alarm installer serving Lyon, the Rhône region and, progressively, customers across France. The company helps homeowners choose and install security systems from Ajax, Somfy and Diagral, with a focus on protection without mandatory subscriptions or long-term commitments. Hysos is an Ajax-certified partner and installs equipment that includes NF-A2P-certified Ajax products.

Its services include a free home-security assessment, a no-obligation quote typically provided within 48 hours, professional installation and after-sales support. Wireless systems can be fitted without major building work, with installation generally taking two to four hours. Depending on the home and chosen setup, systems can include motion and door sensors, a siren and smartphone alerts through the Ajax app. Customers can also choose optional remote monitoring, which can be added later without replacing the equipment.

Hysos provides pricing guidance, product information and comparisons to help customers assess costs and options. The company says it has completed more than 300 installations and emphasizes clear communication, practical advice and transparent customer feedback.
