Intrusion Detection Systems
Multi-layered detection systems that protect your facility from unauthorized entry — combining intelligent sensors, alarm management, and rapid response to deter threats before they cause harm.
Detection first — response made faster
An intrusion detection system is only worth what it does when something actually happens. Legacy Data Technologies designs and installs intrusion systems that are engineered to detect accurately, alert reliably, and integrate with the surveillance and access control infrastructure already in place, so your response to an event is informed and fast, not reactive and fragmented.
Core Capabilities
Control panels & alarm management
Central alarm control panels with programmable zones, arming schedules, and user code management — giving administrators precise, flexible control over when and where the system is active.
Motion detection
PIR, microwave, and dual-technology motion sensors — tuned to minimize false activations from environmental factors while reliably detecting genuine intrusion events.
Door & window contact sensors
Magnetic contact sensors on all entry points — doors, windows, skylights, and roof hatches — that trigger an alarm the moment a protected opening is breached while the system is armed.
Glass break detection
Acoustic glass break sensors that identify the frequency pattern of shattering glass — providing early warning at vulnerable window and glass door entry points.
24/7 alarm monitoring
Professional central station monitoring around the clock — verifying alarm events, notifying designated contacts, and dispatching emergency responders when a genuine intrusion is confirmed.
Remote access & management
Arm, disarm, and monitor your system from any authorized device — with real-time event notifications, zone status visibility, and audit trails of all system activity.
Intrusion detection becomes significantly more powerful when integrated with CCTV and access control. When a sensor triggers, correlated camera footage and entry logs give your team immediate context — reducing false alarm dispatches and accelerating verified response.
A Layered Approach to Protection
Effective intrusion detection isn’t a single device — it’s a coordinated system of overlapping detection layers that ensures threats are caught at the earliest possible point, whether at the perimeter, at an entry point, or inside the facility.
Layer 1 — Perimeter
Fence-mounted sensors, beam detectors, and outdoor motion detectors that identify threats before they reach the building.
Layer 2 — Entry points
Door and window contacts, glass break sensors, and keypad zones protecting every access point into the facility.
Layer 3 — Interior
Internal motion detectors, passive infrared sensors, and duress buttons provide a final line of detection inside secured areas.
