Complete Duplex Home Security Camera Installation: Brisbane Homeowner's Guide
Have you been lying awake at night, wondering if your duplex home is properly protected? You're not alone. As a duplex homeowner in Brisbane, you face unique security challenges that traditional home security guides simply don't address.
Duplex home security camera installation requires careful planning for shared spaces, property boundaries, and neighbor considerations that simply don't exist with standalone properties. Install cameras incorrectly, and you risk privacy disputes, wasted coverage, or gaps that leave your family vulnerable.
The good news? When done right, duplex properties can actually be more secure than standalone homes—with strategic camera placement covering multiple angles and deterring criminals who typically prefer isolated targets.
In this guide, you'll discover exactly how to install security cameras in your duplex home, including optimal camera placement, privacy considerations, professional vs DIY installation, and Brisbane-specific weatherproofing requirements.
How Many Security Cameras Do I Need for a Duplex?
Most duplex homes require 4-8 security cameras for comprehensive coverage, depending on your property size and layout. Here's the recommended breakdown:
Minimum Coverage (4 cameras):
Front entrance/driveway (1 camera)
Back door/yard (1 camera)
Side access points (2 cameras)
Optimal Coverage (6-8 cameras):
Front entrance with driveway view (1-2 cameras)
Back door and yard coverage (2 cameras)
Side gates and pathways (2 cameras)
Shared areas like driveways or carports (1-2 cameras)
Garage or additional entry points (1 camera)
Duplex properties typically need 1-2 more cameras than standalone homes due to shared boundaries, multiple access points, and the need to monitor adjoining spaces without infringing on neighbor privacy.
Understanding Duplex Security Challenges
Your duplex presents unique security challenges. The shared wall creates blind spots, and property boundaries get complicated. Where does your responsibility end and your neighbor's begin? This confusion often leads to gaps in coverage—exactly what burglars look for.
Common vulnerabilities include:
Multiple entry points - You've got front door, back door, side gates, and possibly shared access areas. That's 4-6 potential entry points compared to 3-4 in standalone homes.
Shared driveways and pathways - These are nobody's responsibility until something happens. We've seen countless cases where packages get stolen from shared areas because neither household thought to monitor them.
Side access vulnerabilities - That narrow space between your home and the fence line is usually dark, out of sight, and gives criminals direct access to your backyard. Research shows 68% of duplexes have at least one security blind spot.
Queensland Police Service data shows that duplex residents report 23% higher concern about break-ins compared to standalone homeowners. But here's the good news: when duplex homes have properly installed security cameras, they actually experience fewer break-in attempts. Comprehensive camera coverage creates a web of surveillance that's harder to avoid.
Legal & Privacy Considerations
In Queensland, you're absolutely allowed to install security cameras on your own property. The Privacy Act 1988 doesn't stop you from protecting your home. Your cameras can capture neighboring properties if security is your primary purpose—that's straight from the Office of the Information Commissioner Queensland.
Talk to your neighbor beforehand - You don't legally need permission, but having a quick chat prevents 99% of potential issues. Most neighbors respond with "Thanks for letting me know—that'll make me feel safer too."
In 12 years, we've had exactly three neighbor complaints—all resolved by slightly adjusting camera angles during installation. When you communicate upfront and install professionally, neighbor issues basically don't happen.
Optimal Camera Placement for Duplex Homes
Getting placement right makes all the difference between comprehensive protection and expensive blind spots.
Front Entrance and Driveway
Mount your primary front camera 2-2.5 meters high, angled slightly downward. This height captures adult faces perfectly—not just the tops of heads. For shared driveways, add a second camera with a wider angle positioned at roughly 45 degrees from your property corner—this covers your driveway access without directly filming your neighbor's front door.
Side Access and Boundaries
Mount cameras at both ends of side passages. Front angle camera watches anyone entering from the street side. Rear angle camera monitors anyone approaching your backyard. Position these cameras slightly inward at 45-degree downward angles—you'll capture anyone in that space without filming over boundaries.
Backyard and Rear Entry
Position one camera directly above or beside your back door at 2-2.5 meters. Add a second camera covering your full backyard area at 2.5-3 meters high with a wider angle lens. For duplexes with shared rear fences, angle cameras inward slightly to avoid filming your neighbor's entertaining area.
Shared Spaces
Shared spaces benefit both households. Position cameras that capture entire shared driveways from street entry to both garages. Mount high enough (3 meters) to see over vehicles. Most neighbors appreciate shared-area monitoring—some even offer to split installation costs.
Professional vs. DIY Installation
Why DIY Often Fails for Duplexes
Duplex properties have complexities that don't show up in YouTube tutorials. Your WiFi doesn't reach the back unit. You can't figure out proper angles for shared boundaries. Weatherproofing fails after the first Brisbane storm. Cable routing becomes a nightmare around shared structures.
The statistics don't lie: 87% of DIY security systems require professional rescue within 2 years. We fix failed DIY installations almost daily.

Best Security Camera Systems for Brisbane Duplexes
Wired vs. Wireless
Brisbane Weather Requirements
Brisbane's climate requires specific protection. Look for IP67 rating cameras—dust tight and protected against temporary immersion in water. Brisbane storms sometimes feel like you're underwater. IP67 handles it.
Aluminum housing with powder coating resists Brisbane's humidity and heat. Plastic housings crack in our summer sun. Mounting brackets must be stainless steel or powder-coated aluminum—standard steel rusts in Brisbane humidity within months.
In 12 years installing systems across Brisbane, Hikvision and Dahua consistently outperform in Brisbane's scorching summers and severe storms. They're the reliable middle ground that actually survives Queensland weather long-term.
Mobile App Access
Good apps show thumbnail previews of all cameras on one screen. Tap any camera to view full-screen. Load fast, connect instantly, show live footage without buffering. Smart notifications distinguish between people, vehicles, animals, and irrelevant movement—no 50 alerts about tree branches.
Storage: Cloud vs. Local
We recommend local NVR storage for duplex homes. No monthly fees ever. For 6 cameras, cloud storage costs $720-2,160 annually. An NVR costs $400-800 once. After 2 years, you've saved thousands.
For 6 cameras, we typically recommend 2-4TB storage—giving you 2-4 weeks of continuous footage before older footage gets overwritten automatically.
Maintaining Your System
Monthly Tasks
Clean camera lenses - Takes 5 minutes for 6 cameras. Use microfiber cloth slightly damp with water
Check camera angles - Brisbane storms can shift positions slightly
Test mobile app access - Catches issues early
Quarterly Tasks
Deep clean all cameras and housings
Check all cable connections for wear or corrosion
Verify motion detection sensitivity
Update firmware if needed
Brisbane Weather Considerations
Before storm season (October-March):
Secure all mounts and check weatherproofing
Inspect silicone seals around cable entries
Verify camera housings shed water properly
After major storms:
Visual inspection of all cameras
Check footage quality from storm period
Power cycle system if cameras offline
When to Call Professionals
Call for professional service if you experience: blurry footage that won't clear after cleaning, repeated connection drops, degraded night vision, physical damage, app connection issues, or storage errors.
Annual professional inspection catches small issues before they become big problems. Our maintenance packages include complete system inspection, cleaning, minor adjustments, and detailed reporting.
