In Adelaide, many break-ins happen each year – and many occur not because of sophisticated criminals, but because of simple security mistakes. After over 40 years protecting South Australian homes, our team at Infratec Security Systems has seen the same issues repeated time and again.
The good news? These mistakes are easy to fix once you know what to look out for. Here are the top 10 home security mistakes we see, and the steps you can take to avoid them.
1. Relying on Just One Layer of Security
Many homeowners install a CCTV system and believe that’s enough. But cameras alone don’t stop intruders – they just record what happens. Similarly, an alarm without cameras can miss vital evidence.
Solutions: Combine layers – CCTV, alarm systems, and monitoring. This creates a complete protection strategy that deters, detects, and responds.
2. Hiding Spare Keys in Obvious Places
It’s classic mistake: leaving a spare key under the doormat, in a pot plant, or inside the letterbox. Unfortunately, burglars know exactly where to look.
Solutions: Use a lockable key safe, or upgrade to a smart lock system that eliminates the need for physical spare keys.
3. Forgetting Side Gates and Outdoor Sheds
Unsecured side gates, sheds, and outdoor storage are common weak points. Intruders often use these access points to get closer to the house without being noticed.
Solutions: Install gate locks or automated gates for convenience and security. Extend your alarm system to cover sheds and garages.
4. Leaving Valuables Visible
Expensive bikes, tools, or electronics left visible from the street are easy targets. Even something as simple as a laptop left on a table near a window can tempt opportunists.
Solutions: Keep valuables out of sights, add curtains or blinds, and use motion-sensor lighting combined with CCTV.
5. Relying on DIY Installations
DIY alarm or camera kits might seem cost-effective, but often they’re installed incorrectly – leaving blind spots, weak connections, or systems that aren’t integrated properly.
Solutions: Use a licensed installer who designs systems professionally and ensures monitoring is available. A correctly set up system is far more reliable.
6. Ignoring Alarm & CCTV Maintenance
We often find systems with flat batteries, dusty sensors, or cameras that have been offline for months. A security system that isn’t maintained is effectively useless.
Solutions: Schedule preventive maintenance checks. Our team offers maintenance programs to keep your system in top working order.
7. Skipping Professional Monitoring
Many people rely on smartphone notifications from their DY systems or self monitoring systems. But what if you’re asleep, at work, or on holiday? A missed alert can mean the difference between protection and loss.
Solutions: Invest in Grade 1A professional monitoring. Our 24/7 control room ensures an immediate response – every time.
8. Sharing Holiday Plans on Social Media
It’s tempting to post holiday snaps in real time, but this can signal to potential intruders that your home is empty.
Solutions: Wait until you return to share photos. Consider smart lighting systems that create the impression someone is home while you’re away.
9. Overlooking Garages and Driveways
Garages often contain expensive items – cars, bikes, tools – yet they’re one of the least secured areas. Many aren’t connected to the alarm system at all.
Solutions: Include garages and drive ways in your alarm zones and CCTV coverage. Automated gates add another layer of security.
10. Assuming “It Won’t Happen to Me”
The most common mistake of all is complacency. Many homeowners believe burglaries happen to “other people” – until it happens to them.
Solutions: Take a proactive approach. Even small upgrades, like installing a monitored alarm or adding a camera to blind spots, can dramatically reduce your risk.
Security mistakes are easy to make – but they’re also easy to avoid once you know the risks. At Infratec Security Systems, we’ve been protecting Adelaide homes since 1985 with tailored solutions that combine generational expertise and modern technology.
