Installing security cameras at your home might seem intimidating at first, but with the right preparation and guidance, it's a project most homeowners can tackle themselves over a weekend. Whether you're setting up a single camera to monitor your front door or deploying a comprehensive multi-camera system, this guide will walk you through every step of the process.
Having installed hundreds of security camera systems across Australian homes during my years as a professional installer, I've learned that success comes down to proper planning and understanding a few key principles. Let's break down the entire installation process from start to finish.
Planning Your Camera Placement
Before you drill a single hole or run any cables, you need a solid plan. Poor camera placement is the most common mistake I see homeowners make, and it's one that can render even the best camera ineffective.
Identifying Priority Areas
Start by walking around your property and identifying the areas that need monitoring. Most Australian homes benefit from cameras covering:
- Front entrance: The main entry point where packages are delivered and visitors arrive
- Back door: Often a target for break-ins due to reduced visibility from the street
- Driveway or carport: Protects vehicles and captures anyone approaching your home
- Side gates: Common entry points that are easily overlooked
- Backyard: Monitors outdoor entertaining areas and swimming pools
Walk through your property at night to identify dark spots and areas with challenging lighting conditions. This will help you choose cameras with appropriate night vision capabilities.
Camera Height and Angle
The ideal mounting height for most security cameras is between 2.5 and 3 metres. This height provides several advantages: it's high enough to prevent easy tampering, captures faces rather than the tops of heads, and provides a good field of view. Avoid mounting cameras too high, as this makes it difficult to identify facial features and reduces the effectiveness of motion detection.
Angle your cameras slightly downward, typically between 15 and 30 degrees. This captures more useful detail and reduces the amount of sky in the frame, which can cause exposure problems. For outdoor cameras, consider sun position throughout the day to avoid direct sunlight hitting the lens, which causes glare and washed-out footage.
Gathering Your Tools and Materials
Having the right tools on hand before you start will make the installation process much smoother. Here's what you'll typically need:
- Power drill with masonry and wood bits
- Ladder appropriate for your mounting height
- Screwdriver set (Phillips and flathead)
- Spirit level for ensuring straight mounting
- Cable clips or conduit for outdoor cable runs
- Silicone sealant for weatherproofing outdoor connections
- Stud finder if mounting on internal walls
- Pencil for marking drill points
🔑 Key Takeaway
- Mount cameras between 2.5-3 metres high
- Angle slightly downward (15-30 degrees)
- Avoid direct sunlight on the lens
- Cover all entry points to your property
Step-by-Step Installation Process
Step 1: Test Your Camera Indoors First
Before mounting anything permanently, connect your camera and test it indoors. Download the manufacturer's app, complete the initial setup, and verify that the camera connects to your WiFi network reliably. This saves the frustration of mounting a camera only to discover connectivity issues.
Step 2: Mark Your Mounting Points
Hold the camera or its mounting bracket in position and use a pencil to mark the screw holes. Use a spirit level to ensure the bracket is straight. For brick or render walls, you'll need wall plugs; for timber, screws can go directly into the material.
Step 3: Drill and Mount the Bracket
Drill your holes at the marked points, using the appropriate drill bit for your wall material. Insert wall plugs if required, then secure the mounting bracket with the provided screws. Give the bracket a firm tug to ensure it's securely fastened before attaching the camera.
Step 4: Route Your Cables
For wired cameras, plan your cable route carefully. Run cables through walls where possible, or use weatherproof conduit for exposed outdoor runs. Ensure cables are secured every 30-40 centimetres to prevent sagging or damage. Apply silicone sealant around any holes drilled through external walls to prevent water ingress.
When drilling through external walls, always drill at a slight downward angle from inside to outside. This prevents water from running along the cable and into your home.
Step 5: Attach and Adjust the Camera
Mount the camera on its bracket and connect any cables. Use the app's live view to adjust the angle and position while watching on your phone. This two-person job is much easier if someone watches the app while another adjusts the camera. Once positioned correctly, tighten all adjustment screws firmly.
Step 6: Configure Detection Zones
Most modern cameras allow you to define motion detection zones. Take time to configure these properly, excluding areas with frequent movement that you don't need to monitor, such as busy streets or trees that move in the wind. This dramatically reduces false alerts and makes your notifications meaningful.
Wireless vs Wired Installation Considerations
The installation process differs significantly depending on whether you're installing wireless or wired cameras. Wireless cameras are generally easier to install since you only need to mount the camera and ensure it has power, either from batteries or a nearby outlet. However, you must verify that WiFi signal strength is adequate at each camera location before permanent installation.
Wired cameras require more installation effort but offer reliable connectivity and consistent power. Power over Ethernet (PoE) systems are particularly convenient, as a single cable provides both power and data connection. These systems are ideal for permanent installations where reliability is paramount.
Testing Your Installation
After mounting all cameras, conduct thorough testing over several days. Check video quality at different times, including night time, to verify night vision performance. Walk through detection zones to confirm motion alerts trigger appropriately. Test remote viewing from outside your home network to ensure you can monitor your property while away.
Pay particular attention to how cameras perform in Australian conditions. Our harsh sun can cause overexposure issues, while sudden temperature changes may trigger false motion alerts. Adjust settings as needed based on real-world performance.

Common Installation Mistakes to Avoid
Over the years, I've seen the same mistakes repeated. Avoid these common pitfalls:
- Mounting too high: Cameras above 4 metres rarely capture useful facial details
- Ignoring WiFi range: Test signal strength before mounting wireless cameras
- Poor weatherproofing: Water damage is the leading cause of outdoor camera failure
- Overlooking power requirements: Ensure nearby power sources for wired cameras
- Neglecting lighting: Even the best camera needs adequate lighting for clear footage
With careful planning and methodical installation, you can achieve professional-quality results with a DIY security camera installation. Take your time, test thoroughly, and don't hesitate to adjust camera positions if the footage isn't quite right. A well-installed camera system provides years of reliable home security and peace of mind.
