Wireless and wired intrusion alarm systems for homes and businesses, designed around your entry points and layout — not a one-size-fits-all kit pulled off a shelf.
The focused diagram shows only the system nodes covered by this page. Read the highlighted path, role and scope condition to understand what is included and what needs separate confirmation.
Connects selected detectors, panel logic, user controls, local warning, communication and optional visual verification.
This page covers: Selected detectors report to the alarm panel or hub and trigger only the agreed local or communication response.
Open component 01 in the complete Solution →An alarm system is only as reliable as its sensor placement. We plan sensor and keypad locations around how you actually move through the property, so the system arms and disarms cleanly without nuisance triggers, and covers the entry points that matter most.
A well-designed alarm system combines a few sensor types, placed where they actually matter for your property.
Detect movement across a room or corridor — the most common sensor for covering open interior spaces.
Magnetic sensors that trigger the instant a door or window is opened — placed at every entry point during the survey.
Listen for the specific frequency of breaking glass — useful for large windows or sliding doors where a contact sensor alone isn't enough.
Sensors facing windows or air-conditioning vents trigger constantly, until the household stops arming it altogether.
An alarm alone deters — paired with cameras, you also get a recorded record of what actually happened.
Systems installed without a proper handover often sit unarmed because the household never learned the daily routine.
We walk the property with you, identify entry points and everyday movement patterns, and place sensors to cover real risk areas without tripping every time someone walks past. Every installation includes a walkthrough so your household or staff know how to arm and disarm confidently from day one.
We map entry points and everyday movement patterns on-site.
Sensor zones and panel choice matched to your property.
Clean sensor, keypad and siren installation by our own technicians.
Full arm/disarm test and walkthrough with your household or staff.
Optional AMC maintenance to keep sensors and batteries in check.
Sensor batteries fade and sensitivity drifts over time. Our maintenance (AMC) plans include regular checks so your alarm stays reliable, not just installed.
