The Complete Home Security Guide for Adelaide Homeowners

Adelaide is a great place to live, but no suburb is immune to break-ins. Whether you are in the eastern suburbs, along the coast, or further out in the Adelaide Hills, taking a few deliberate steps to secure your home can make a significant difference. This guide covers everything from basic door and window security through to alarm systems, CCTV, and access control — so you can build a layered approach that suits your property and your budget.

Why Adelaide Homeowners Need to Think About Security

Property crime remains one of the most common offence categories in South Australia. According to national crime data, break-ins and attempted break-ins rose across Australia in 2023-24, and Adelaide was not exempt from that trend. You can read more about local statistics in our Adelaide crime statistics breakdown.

The important thing to understand is that the vast majority of residential break-ins are opportunistic. Offenders look for easy targets — unlocked doors, open windows, dark properties, and homes that clearly appear unoccupied. They are not typically planning elaborate heists. They are walking or driving through a neighbourhood looking for the path of least resistance.

That is actually encouraging news, because it means simple, practical measures genuinely work. A locked deadbolt, a sensor light, a visible camera — each one adds a layer of deterrence that makes your home less attractive to an opportunist. When you combine multiple layers, you create a security posture that sends a very clear message: this home is not worth the risk.

This guide takes you through those layers one at a time, starting with the most basic steps and working up to full security systems. You do not need to do everything at once. Even implementing a handful of the suggestions below will improve your security meaningfully.

Start With the Basics: Doors and Windows

Doors and windows are the most common entry points for break-ins. It sounds obvious, but a surprising number of burglaries occur through unlocked doors or windows that were left open. Before you think about cameras and alarms, make sure the physical entry points of your home are properly secured.

Front and Back Doors

Every external door should have a deadlock that conforms to Australian Standard AS 4145.2. These locks are rated for resistance against picking, drilling, and forced entry. A simple spring-latch lock on its own is not sufficient — it can be bypassed with a credit card or a thin tool in seconds. A quality deadlock is your first real line of defence.

Check your door frames as well. A strong lock in a weak frame is like putting a padlock on a cardboard box. Reinforce timber frames with longer screws that anchor into the wall studs, not just the door jamb. Steel striker plates with three-inch screws make a meaningful difference to kick resistance.

If your home has a sliding door, invest in a sliding door lock or a security bar that prevents the door from being lifted off its track or forced open. Many older Adelaide homes have aluminium sliding doors that are particularly vulnerable without additional locking hardware.

Windows

Window locks are inexpensive and straightforward to install. Key-operated window restrictors allow you to lock windows in a partially open position, which is useful for ventilation without compromising security. This is particularly relevant during Adelaide's warmer months when leaving windows open overnight is tempting.

Pay attention to louvre windows — they are common in older South Australian homes and are notoriously easy to remove from the outside. If you have louvre windows in accessible locations, consider replacing them or fitting security screens.

Habits That Matter

Never leave keys in locks or hanging on hooks near doors where they can be reached through a letterbox or broken panel. Do not hide spare keys under doormats, pot plants, or fake rocks — these hiding spots are well known to offenders. If you need to leave a spare key accessible, give it to a trusted neighbour instead.

Consider fitting a peephole or door viewer to your front door so you can identify visitors before opening up. Wide-angle peepholes are inexpensive and take minutes to install.

Exterior: Your First Line of Defence

The area around your home is the first thing a potential intruder assesses. A well-lit, well-maintained exterior with clear sightlines signals that the property is cared for and likely secured. A dark, overgrown property with plenty of hiding spots signals the opposite.

Lighting

Automatic sensor lights are one of the most cost-effective security measures you can install. Position them at every entry point — front door, back door, side gates, and garage. A sudden flood of light is a strong deterrent to anyone approaching your property at night.

For areas that are always visible from the street, timer-controlled lighting can create the impression that someone is home even when the house is empty. Smart bulbs or timer switches allow you to set schedules that vary slightly each day, which looks more natural than a light that comes on at exactly the same time every evening.

Landscaping

Trim hedges and shrubs below window height, particularly along the front of your property and beside entry points. Dense bushes next to windows or doors provide concealment for someone trying to force entry. Gravel paths alongside the house are a low-tech but effective measure — they make noise underfoot, which is a natural alarm in itself.

If you have large trees near the house, ensure branches do not provide easy access to upper-storey windows or the roof. This is especially relevant for two-storey homes in suburbs with established gardens.

Fencing, Gates, and Access

Side gates should be lockable from both sides. Many break-ins involve entry through a side gate that leads to the backyard, where the offender can work on a back door or window out of sight from the street. A simple padlock or key-operated gate latch addresses this.

Your front fence and driveway should allow clear sightlines from the street to your front door. Solid, high front fences can actually work against you by providing concealment once someone is inside your property boundary. A balance between privacy and visibility is ideal.

Letterbox and Bins

An overflowing letterbox is one of the clearest signals that nobody is home. When you are away, arrange for a neighbour or friend to collect your mail. The same applies to bins — if your bins are left out on the kerb for days after collection day, it tells anyone watching that the house is empty.

Making Your Home Look Occupied

Deterrence is about perception. If your home looks occupied, an opportunistic offender will move on to an easier target. There are several simple strategies that create the impression of activity even when you are away.

Timer switches for lights are a starting point. Set them to turn on lamps in different rooms at staggered times during the evening. You can also use smart plugs to control a television or radio, adding sound and the flicker of a screen to the illusion.

If you have a second car, leave it in the driveway. A car parked out front is one of the strongest indicators that someone is home. If you are going away and both vehicles are travelling with you, ask a neighbour or friend to park in your driveway occasionally.

Ask a trusted neighbour to collect your mail, bring in your bins, and generally keep an eye on your property. Neighbourhood relationships are one of the most underrated security measures. A neighbour who knows your routine will notice when something is off.

One often-overlooked detail: do not leave packaging for expensive items — televisions, computers, gaming consoles — visible at the kerb on bin night. Break down the boxes and place them inside the bin, or take them directly to a recycling centre. Packaging on the kerb is an advertisement for what is inside your home.

Alarm Systems: What to Look For

An alarm system is one of the most effective security investments you can make. Modern systems are far more sophisticated and user-friendly than the basic setups of a decade ago, and there are options to suit every property type and budget.

Wired vs Wireless

Wired alarm systems use physical cabling between the control panel and each sensor. They are extremely reliable and are not subject to wireless interference or battery issues. However, they require more involved installation, which makes them better suited to new builds, renovations, or properties where cable runs can be concealed neatly.

Wireless systems communicate via radio frequency between sensors and the panel. They are faster to install, less disruptive to existing interiors, and easier to expand over time. Modern wireless alarm technology is highly reliable, with encrypted signals and tamper detection. For most existing Adelaide homes, a wireless system is the practical choice.

Zones and Arming Modes

Alarm systems divide your property into zones — front door, back door, hallway, garage, and so on. Each zone can be configured independently, which allows for flexible arming modes:

• Away mode: Arms all zones. Used when the entire household is out.
• Stay mode: Arms perimeter zones (doors and windows) while leaving internal motion sensors inactive. Used when you are home and moving around inside.
• Night mode: Similar to stay mode but may include specific internal zones such as hallways or living areas that you would not normally enter while sleeping.

These modes mean you can have your alarm working for you at all times — not just when you leave the house.

Mobile App Control and Monitoring

Most modern alarm panels offer app-based control, allowing you to arm, disarm, and check the status of your system from your phone. You will receive push notifications if an alarm triggers, and you can review event logs to see exactly what happened and when.

When it comes to monitoring, you have two main options. Self-monitoring means you receive alerts directly and decide how to respond. Professional monitoring means a monitoring centre receives the alert and can dispatch a response or contact you and the authorities on your behalf. Professional monitoring provides an additional layer of assurance, particularly when you are travelling or unable to respond quickly.

CCTV and Security Cameras

Security cameras serve two purposes: deterrence and evidence. A visible camera discourages opportunistic offenders, and recorded footage provides critical evidence if an incident does occur. Modern camera systems are more accessible, more capable, and more affordable than ever.

Camera Types

The three most common camera types for residential use are:

• Dome cameras: Compact and discreet, mounted flush to ceilings or soffits. Their dome housing makes it difficult to tell which direction the camera is pointing, which adds to their deterrent value.
• Bullet cameras: Cylindrical and more visible. They are well-suited to outdoor use and are effective for covering longer distances such as driveways and fence lines.
• PTZ cameras (Pan-Tilt-Zoom): These can be remotely controlled to pan across an area, tilt up and down, and zoom into specific points. They are more commonly used in commercial settings but can be valuable for larger residential properties.

Resolution and Night Vision

Camera resolution directly affects the usability of your footage. A 1080p (Full HD) camera is adequate for general surveillance, but if you need to identify faces or read number plates, 4K resolution is a worthwhile investment. The difference becomes particularly evident when you need to zoom into footage after the fact.

Night vision is essential. Most security cameras use infrared (IR) LEDs to illuminate the scene in complete darkness. Higher-end cameras offer colour night vision using supplemental white-light LEDs, which provides more detail than traditional black-and-white IR footage. Given that most break-ins occur during darkness or low-light conditions, night vision quality should be a priority.

Storage Options

Footage needs to be stored somewhere accessible and secure. The main options are:

• NVR (Network Video Recorder): A local device that stores footage on internal hard drives. Reliable, fast to access, and not dependent on internet speed. This is the most common setup for residential systems.
• Cloud storage: Footage is uploaded to a remote server. Useful as a backup, but dependent on your internet upload speed and usually involves an ongoing subscription fee.
• Hybrid: Local recording with cloud backup for critical events. This gives you the reliability of local storage with the redundancy of cloud access.

Camera Placement Priorities

For most Adelaide homes, the highest-priority camera positions are:

1. Front door: The most common point of approach for both visitors and intruders.
2. Driveway: Captures vehicles and foot traffic approaching the property.
3. Side access: Covers gates and pathways that lead to the backyard.
4. Backyard: Monitors the rear of the property, including back doors and sheds.

Privacy Considerations

In South Australia, you are entitled to install cameras on your own property, but you should be mindful of your neighbours' privacy. Avoid positioning cameras so they look directly into a neighbour's windows or private outdoor areas. Focus your camera angles on your own property boundaries and entry points. Being considerate here avoids disputes and is simply good practice.

All modern systems offer remote access via smartphone apps, so you can check your cameras from anywhere with an internet connection. For a detailed look at costs, see our guide to security camera costs in Adelaide. You can also explore our CCTV installation services for more on what we offer.

Access Control for Residential Properties

Access control is not just for offices and commercial buildings. Residential access control solutions have become increasingly practical and affordable, and they solve real everyday problems for homeowners.

Smart Locks and Keyless Entry

Smart locks replace or supplement traditional keyed locks with PIN codes, smartphone access, or biometric authentication (fingerprint). They eliminate the risk of lost keys and allow you to grant and revoke access remotely. If your cleaner comes every Tuesday, you can set a recurring code that only works during their scheduled hours. If a tradie needs access for a one-off job, you can create a temporary code that expires automatically.

This is especially useful for managing access for cleaners, tradespeople, pet sitters, and family members who may need to come and go on different schedules. You maintain a full audit trail of who entered and when, which adds a layer of accountability that traditional keys cannot provide.

Intercom Systems

Video intercom systems let you see and speak to visitors at your front door or gate before granting access. Modern intercoms connect to your smartphone, so you can answer the door from anywhere — whether you are in the backyard, at work, or on holiday. Some systems integrate with electric gate or door releases, allowing you to let a visitor in without physically going to the door.

Gate Automation

Automated gates add both security and convenience. A gate that opens and closes automatically removes the need to get out of your car in the driveway — which is a practical benefit, but also a security one. It means your property boundary is secured as soon as you drive through, and it controls who can approach your front door.

Securing Garages, Sheds and Outbuildings

Garages, sheds, and outbuildings are frequently overlooked in home security planning, and offenders know this. A detached garage or garden shed can contain valuable tools, bicycles, power equipment, and other items that are easy to carry away.

Start with the basics: fit quality padlocks and heavy-duty hasps to shed doors. Cheap padlocks can be cut with bolt cutters in seconds — invest in a padlock with a hardened steel shackle rated for outdoor use.

Garage doors are another common weak point. Older tilt-a-door and roller doors can be forced open relatively easily. Modern sectional garage doors with auto-locking mechanisms are more resistant. If your garage is attached to your house and has an internal access door, treat that door as an external entry point — fit a deadlock and keep it locked.

Extend your sensor lighting to cover detached buildings. A sensor light on the side of a garage or shed provides deterrence and alerts you to movement in those areas at night.

When to Call a Professional

Many of the measures in this guide are things you can do yourself — fitting window locks, installing sensor lights, improving your landscaping, and developing better security habits. These are all worthwhile and effective steps.

However, there comes a point where professional advice and installation makes a real difference. Here are some signs it might be time to bring in a specialist:

• You want an alarm system: Proper alarm installation involves sensor placement, zone configuration, panel programming, and integration with monitoring services. Getting this right from the start avoids false alarms and coverage gaps.
• You want CCTV coverage: Camera positioning, cable routing, NVR setup, and network configuration all benefit from professional knowledge. A poorly positioned camera is worse than no camera — it gives you a false sense of security.
• Your property has specific vulnerabilities: Corner blocks, properties backing onto laneways, homes with extensive side access, and houses screened by vegetation all have unique security challenges that benefit from a trained eye.
• You have had a break-in or attempted break-in: If your property has already been targeted, a professional assessment can identify how the offender gained or attempted to gain entry and what measures will prevent a recurrence.
• Your existing system is outdated: If your alarm or camera system is more than eight to ten years old, it is likely due for an upgrade. Older systems may lack mobile connectivity, have outdated sensors, or no longer be supported by their manufacturer.

A professional security assessment looks at things you might not consider — the angle of approach from the street, the lighting conditions at different times of night, the signal strength for wireless sensors in different parts of your home, and how your property's layout affects camera coverage. It is a trained perspective that goes beyond simply installing equipment.
