Alarm Monitoring Perth

At 2:47am on a Tuesday, a motion sensor tripped inside a West Perth warehouse we monitor. Our Grade A1 control rooms had WA Police notified within 90 seconds and the owner on a phone call before the patrol car turned into the street. The intruder was arrested on-site.

That is the alarm monitoring in Perth businesses actually need. At Castle Security, founded in 1989 by Bill and Val Thorp as Castle Security & Electrical, family-owned, running security monitoring Perth operations from Unit 2, 9 Fallon Road, Landsdale.

24 Hour Alarm Monitoring

What Is Alarm Monitoring?

Alarm monitoring is a 24/7 professional monitoring service that watches your alarm system for triggered events and responds before a situation escalates. When a sensor, door contact or panic alarm fires, the signal transmits over a dedicated phone line, IP path or 4G backup to our monitoring centres, is assessed by a licensed operator, and is escalated within seconds. Depending on event type, we dispatch emergency services, notify your contact, or verify via video surveillance before calling police, which cuts false alarms.

Our Security Monitoring Services

We run alarm monitoring services across residential, commercial and industrial sites in Perth and regional Western Australia. Residential clients get 24/7 monitoring for home alarms, break in detection, medical duress and fire.

Commercial properties add lone workers duress, after-hours access monitoring, and integration with CCTV and motion sensors so a signal is matched against live video before police are dispatched. Plans start from $20 per month and scale as devices are added.

How Our Grade A1 Monitoring Centre Works

Alarm events are handled through a Grade A1 monitoring centre with redundant power, dual carrier links and operators licensed by WA Police Licensing Services. When your alarm system signals an event, the operator matches it to your site profile, verifies with video where available, and follows the exact response plan you approved at installation. Average operator response sits below 45 seconds. Reporting is available on-demand, so you can review every event across the last 12 months without lodging a support ticket.

Types Of Systems We Monitor

We monitor security systems we installed and systems installed by other providers, provided the panel supports Contact ID or SIA reporting.

Home Security Systems. Motion sensors, reed switches on doors and windows, bedside panic buttons and smoke detectors tied into the same alarm.

Business Security Alarms. Multi-partition panels for retail and commercial premises, with separate codes per user and per zone.

CCTV Verified Alarms. Security cameras tied to alarm events so the operator watches the scene before calling police, dropping false dispatches.

Medical And Duress. Pendant and fixed panic alarm buttons for vulnerable residents and lone workers, with medical escalation built in.

Remote Access And Mobile. App-based control so you can arm, disarm and stay connected from a mobile device anywhere in Australia.

Why Castle Security For Alarm Monitoring

We have protected Perth premises for over three decades. We won our first State Government school contracts in 1993, became an accredited Gallagher Security partner in 2015, and hold our own stock of Bosch, Inner Range and Paradox panels at Landsdale so a failed device is replaced within 48 hours. We are members of the Australian Security Industry Association, fully licensed, and we run our own technicians rather than sub-contracting, so the installer who commissioned your alarm is the team that answers when it misbehaves. Our industry advice reflects what we see happening in Perth, not what a national call centre reads off a script.

Case Study: Monitoring Upgrade in West Perth

Before:

A small office in West Perth relied on a legacy alarm system connected to a landline. After a false alarm triggered an emergency call-out, the business wanted to upgrade to a more accurate, monitored alarm.

After:

Castle Security installed a wireless alarm system with motion detectors, CCTV integration, and 24/7 monitoring. The system now alerts the business owner via mobile phone and escalates only verified alerts to emergency services. The client now enjoys consistent monitoring and appropriate action in response to any alarm signal.

Central Monitoring Services You Can Trust

Our central monitoring services in Western Australia are designed to detect break-ins, fires, and medical emergencies. When an emergency occurs, the system sends a signal to our Grade A1 control centre where trained operators verify the alert and notify the appropriate authorities. Duress alarms can also be triggered for fast emergency contact. We use passive infrared motion detectors, smoke and heat sensors, and pet-friendly devices to reduce false alarms. Video door phones and perimeter alarms add another layer of protection, while wireless alarm systems are ideal for homes with installation restrictions. Technicians inspect and maintain each system to ensure full coverage across windows, doors, and high-risk entry points. All systems can integrate with smart home automation for remote control and live notifications.
