LICENSED PERTH INSTALLERS OF PARADOX, RELIANCE XR/HILLS AND DAHUA COMMERCIAL ALARM SYSTEMS
Building a business and acquiring all of the assets within a premise is no small feat. The last thing you want is for your years of hard work to be left exposed and for you left empty handed. A commercially-savvy security system truly is your best defence.
Commercial alarms are typically more advanced than their residential counterparts. In addition to intruder detection, they offer a range of features specific to the needs of a business environment, for example panic buttons, integrated access control, user allocation and much more.
With instant automated alerts, remote access, and the ability to integrate with other security systems, when you choose Decode Security to install your commercial alarm system you can rest assured knowing your business assets are protected and you're in control.
SOME OF THE PERTH BUSINESSES & ORGANISATIONS WE'VE SUPPORTED
Automated Alerts
With all of our commercial alarms we can set up automated alerts via text or email for key business managers or personnel in case of security breaches or other emergencies.
Wireless & Hard Wired Options
Based on your preference, we can install your alarm as wireless, hard-wired, or even a mix of both depending on the manufacturer we go with. If you're renting your premise, this can give you greater flexibility should you ever need to relocate.
Varied Monitoring Options
All of our commercial alarm bundles come with user-friendly apps, which allow 24/7 self monitoring. Additionally, a professional security company can also monitor your space, alerting authorities or sending a response team if the alarm is triggered.

"They make sure everything is working properly..."
Jason, Kaz, and the team have been a pleasure to work with across many of my properties. They make sure everything is working properly, and if not, they come back, no issues or extra charges. I’ve been very impressed with their service over many years now.
- PAUL, OWNER OF BEAVER TREE SERVICES
"Love your work guys..."
We had Jason from Decode out to our business to fix up the mess of a security system that had been installed long ago by another company. Jason also added new cameras and set up some other features for extra monitoring. Such a knowledgeable professional. We are so happy with how our security system is functioning now! We’re so stoked with the work that we’re getting Jason to fit out our home with cameras and security too. Love your work guys!

Commercial Alarm System FAQs
-
How does a burglar alarm work?A burglar alarm uses sensors on doors, windows, or within rooms to detect motion or entry. When triggered, it activates an alert system — audible, visual, or remote. When installing your alarm system we can walk you through which kinds of sensors and alerts are best suited to you and your property.
-
What types of sensors are used in burglar alarms?Common types of burglar alarm sensors include door/window contact sensors, motion detectors (PIR), glass-break sensors, and vibration sensors. At Decode Security, we can advise which sensors are best suited to your property and preferences.
-
Can I control my burglar alarm remotely?Yes, most modern systems can be controlled through smartphone apps—allowing arming, disarming, and real-time alerts. At Decode Security, our preferred manufacturers Paradox, Reliance XR (previously Hills), and Dahua all offer this capability.
-
What happens when my home alarm is triggered?When your home alarm goes off the system sounds a siren, notifies you via app or SMS, and may contact a professional monitoring service if connected.
-
Are burglar alarms effective?Yes, visible alarms and signage significantly deter intruders. They also speed up response times in emergencies. At Decode we're BIG believers in having a proactive approach to home security. Don't wait for the bad thing to happen. Get a system installed and secure your home from the get-go.
-
Do burglar alarms work during power outages?At Decode Security, the home alarms we install have battery backups to ensure continued operation during outages. You can also opt for a UPS to be integrated too for further peace of mind.
-
Is professional installation required for home alarms?For the systems we use, yes. Professional installation ensures correct setup, optimal sensor placement, and integration with other security systems (if you have them). Plus it means we're then always there in your back pocket should you ever need us.
-
Can I use a burglar alarm in a rental property?Yes—wireless systems are ideal for renters since they don’t require permanent changes and can be moved easily. At Decode Security we offer both hard-wired and wireless home alarm systems.
