Wireless indoor alarm system with app control — installed in hours, not days.
The classic alarm system with key switches and cable conduits is dead. Ajax is a completely wireless, battery-powered alarm system that you operate yourself via app — from anywhere in the world. We install the system without chiselling work in 4–8 hours, depending on size. In ten years you might need to touch it twice — to change batteries.
Hub 2 / Hub 2 Plus as the reliable heart of the installation
The Hub 2 control panel is the brain — it communicates with all sensors via the encrypted Jeweller radio protocol, forwards alarms to you and to the monitoring centre, and controls the sirens. Four communication paths in parallel: LAN, WiFi and two SIM cards — if one fails, the next takes over instantly. In a power outage the built-in backup battery keeps the system running for 16 hours.
The most important indoor sensor types
We combine sensors depending on the property: DoorProtect (magnetic contact for doors/windows — detects opening), MotionProtect (PIR motion detector — with pet immunity up to 20 kg), GlassProtect (acoustic glass-break detector — reacts to the characteristic sound of breaking glass), CombiProtect (motion + glass-break in one device), KeyPad (control panel with code entry), HomeSiren (indoor siren at 105 dB).
Video overview
Ajax Hub 2 — complete installation of an alarm system in a residential property
Operating via app, keypad or key fob
Arming/disarming the system works via the Ajax app (iOS/Android), the KeyPad control panel or a SpaceControl wireless key fob. You can arm sub-areas separately — e.g. activate only the ground floor while you sleep upstairs. With photo verification (MotionCam sensors) you immediately see the image with every alarm.
