Keeping your home secure is one of the best ways to protect your family and your belongings. A well-designed security system deters break-ins, gives you fast warning when something is wrong, and quietly improves day-to-day life - automated lights, smart locks, package alerts and more.

With so many options on the market it can be hard to know where to start. From DIY kits to fully professional installs with monitoring, the right system for a Perth home depends on the property, the routine and the budget.

Start With The Three Foundations

Cameras: visible deterrence and clear footage if something does happen. A 4-camera CCTV setup covers most single-storey Perth homes.
Alarm system: motion sensors and door contacts with a loud siren and mobile alerts.
Front-door visibility: a hard-wired video doorbell so you can see and speak to anyone at the door.

Adding Smart-Home Integration

Once the foundations are in place, smart-home integration multiplies their value. Lights that flick on when motion is detected at night, smart locks that auto-lock at bedtime, voice control via Alexa or Google Nest, and routines that "arm" the home when everyone leaves.

DIY vs Professional Install

DIY kits are appealing for cost, but they often miss the basics: correct sensor placement, weather-rated cabling, hard-wired power, integration with existing wiring, and proper configuration of the mobile app and notifications. A professional install gets it right the first time - and you get a licensed electrician's warranty on the workmanship.

What A Perth-Ready Setup Looks Like

4 × 5MP POE cameras covering front, rear, driveway and side access - see our CCTV installation packages
NVR with 2TB+ surveillance hard drive for 24/7 recording
Hard-wired video doorbell with motion zones tuned for the street
Alarm panel with PIRs in living areas and door contacts on entry points
Smart locks on the front and garage internal doors
Optional back-to-base monitoring for added peace of mind

Camera Placement That Actually Works In Perth Homes

Camera count matters less than camera placement. Four cameras placed well outperform eight cameras placed poorly. On a typical single-storey Perth home the priority order is:

Front driveway looking down the drive - captures vehicles and anyone approaching the front door, at a shallow enough angle to catch a face rather than the top of a hoodie.
Rear yard / patio - the most common break-in point on Perth homes, especially properties backing onto a park or rear laneway.
Side access gate - the "invisible" route between the front and rear yard. A single turret camera at 2.4m covering the gate is often the highest-value camera on the whole install.
Front door at chest height - handled by the video doorbell, not a wall-mount CCTV.

Mount cameras between 2.4m and 3m high - low enough to capture faces, high enough to discourage tampering, and always angled so at least one shot puts the sun behind the camera during the worst-glare hour. We work this out on the site visit rather than guessing from the driveway.

What Perth-Specific Conditions Change

Salt air on coastal homes (Cottesloe, City Beach, Halls Head, Mandurah canal properties) needs IP66/IP67-rated marine-grade housings and stainless brackets - standard powder-coated brackets will rust through in 2-3 years.
Summer heat pushes camera electronics; we spec cameras rated to 60°C operating temperature and avoid mounting them in unshaded west-facing wall positions wherever possible.
Older brick-veneer construction means cable runs through the roof cavity rather than through walls. Newer double-brick homes need conduit routing along eaves. We plan the cable path before quoting.
Rear-laneway estates in Alkimos, Aubin Grove, Ellenbrook and similar need extra coverage on the laneway side - laneways are a favoured entry point because they're unlit and unobserved.

What About Monitoring And Insurance Discounts?

Back-to-base monitoring - where a 24/7 control room dispatches security or police on an alarm trigger - costs $30-$60/month through a third-party control room in Perth. Whether it's worth it depends on your insurance policy: several Australian insurers discount home contents premiums by 5-15% for a monitored alarm, which often pays for the monitoring fee outright. Ask your insurer for their exact requirements (typically a Class 5 alarm panel and an AS/NZS-compliant install) before signing a monitoring contract.

How Long A Well-Specced Setup Lasts

A properly installed CCTV and alarm setup with brand-name hardware should give you 8-10+ years of service before the cameras' image sensors start noticeably ageing. The NVR hard drive is the wear item - Purple / WD Purple surveillance drives are rated for 24/7 write cycles and typically last 5-7 years before we recommend a swap. Firmware updates over that lifespan add new AI features and patch security issues without needing to replace the hardware.
