Estimated breakdown for your configuration
DIY camera kits are cheap but a professionally installed and monitored system is more reliable and can reduce home insurance premiums, ask your insurer.
Ways to save
- An alarm plus a couple of visible cameras deters most opportunistic break-ins for far less than a full smart system.
- Self-monitored (app alerts to your phone) avoids the ongoing monitoring fee.

What a home security system costs in Perth
A home security system in Perth is priced by the hardware and whether it is professionally monitored, so the up-front cost follows the number of sensors, cameras, the panel and keypad, with a monthly fee for a monitoring service. A self-monitored kit that alerts your phone is the budget tier, a camera-and-hub system a step up, and a professionally monitored back-to-base system the premium ongoing option.
Perth's common double-brick construction favours a wireless system, because running security cabling through solid masonry walls is hard work, so a wireless system that avoids chasing brick is often the practical choice, and it also suits a renter who leaves no wiring behind. The hot, dry Mediterranean climate is kind to outdoor cameras, though the intense summer sun means an outdoor camera needs UV and heat rating, and fine wind-blown sand can foul an exposed lens over time. A larger home on a bigger block needs more cameras to cover the perimeter. The isolation of the WA market rarely affects a standard system but can add lead time for a specialist component. Labour sits near the national average, and self-monitored versus monitored is the ongoing-cost call.
A home security system's install is largely a specialist low-voltage job rather than a licensed building trade, but a hardwired system's mains parts need a licensed electrician, and security installation and monitoring in Western Australia fall under state security licensing, so the installer and monitoring provider must be licensed. For a Perth home, the clearest way to price a home security system is by the components, with a wireless system suiting double-brick walls, plus any monthly monitoring fee.
