Intrusion alarm
Know instantly if someone gets in. Wherever you are.
Installation of AJAX intrusion alarm systems for villas, seasonal homes and businesses: wireless sensors, sirens, keypads and app. Phone notification in seconds, integration with cameras.
A house in Costa Smeralda sits empty for months. AJAX is a professional wireless system: installed without marks on the walls, controlled from the app, it alerts you and whoever you choose, and with Hikvision cameras it shows you what is happening.

Who it is for
For the villa
Door and window contacts, pet-immune motion detectors, outdoor siren, arming via app, keypad or key fob. Every family member has their own access.
For the seasonal home
Beyond intrusion: flood, smoke and power-loss sensors. Alerts also reach whoever manages the house. In winter the connection stays on a minimal Starlink plan.
For shops, offices and warehouses
Separate zones, partial arming at the end of the shift, event history, integration with video surveillance and access control.
