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.
How we estimate this
A home security system in Australia typically costs $500 to $6,000 installed in 2026 depending on home size and components. An alarm only is cheapest; a full smart system with cameras, sensors and monitoring across a large home reaches the top.

What a home security system costs in Sydney
A home security system in Sydney is priced by the hardware it includes and whether it is professionally monitored, so the up-front cost tracks the number of sensors, cameras, the control panel and keypad, while an ongoing monthly fee applies if a monitoring service watches the alarm. A basic self-monitored kit with a few door and motion sensors that alerts your phone is the cheapest tier, a system with cameras and a smart hub is a step up, and a professionally monitored system with a back-to-base service that calls a patrol or the police is the premium ongoing option.
The split that matters in Sydney is self-monitored versus professionally monitored: a self-monitored system has no monthly fee but relies on you responding to an alert, while a monitored system adds a recurring subscription for a monitoring centre to act on an alarm. A terrace in the eastern suburbs with a tight footprint needs fewer sensors than a large house, and the city's highest trade rates lift a professional install. A strata apartment may rely on building security and need only an entry sensor and a camera, and a renter often chooses a wireless, self-monitored system that leaves no wiring behind.
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-powered components need a licensed electrician, and security installation and monitoring in New South Wales fall under state security licensing, so the installer and the monitoring provider must be licensed. For a Sydney home, the clearest way to price a home security system is by the components plus any monthly monitoring fee.

Is self-monitored or monitored cheaper in Sydney?
Self-monitored has no monthly fee but relies on you responding to an alert, while a professionally monitored system adds a recurring subscription for a monitoring centre to act on an alarm, so the choice sets the ongoing cost in Sydney.
Does an apartment need less security in Sydney?
Often. A strata apartment may rely on building security and need only an entry sensor and a camera, while a renter often chooses a wireless, self-monitored system that leaves no wiring behind, unlike a large eastern-suburbs house needing more sensors.
Do I need a licence for a home security system in Sydney?
The install is largely a specialist low-voltage job, but a hardwired system's mains components need a licensed electrician, and security installation and monitoring fall under state security licensing in New South Wales, so the installer and monitor must be licensed.
