Intrusion protection is the core of the Ajax system: it covers every way into the premises and every way to control what happens next. Motion, opening and glass-break detectors watch the rooms; outdoor sensors guard the perimeter before anyone reaches a door; hubs tie everything together over the encrypted Jeweller radio and keep working through power and internet outages.

Around that core sit the controls — keypads and fobs for arming without a phone, panic buttons for emergencies, and indoor and outdoor sirens that make sure an alarm is impossible to ignore. Pick a direction below to browse the devices.
