How Much Does a Security System Cost in Perth? (2026 Price Guide)

Home Alarm System Costs in Perth

Basic wireless alarm systems — the kind most Perth homeowners start with — cover the essentials: a control panel, 3–4 door/window or motion sensors, a keypad, and a siren. Installed by a licensed technician, this generally costs $800–$1,800. Brands like Ajax and Bosch dominate this end of the market because they’re reliable, expandable, and don’t lock you into proprietary gear.

Full systems with cameras and extra sensors push the price to $1,200–$4,500, depending on how many rooms, entry points and outdoor areas you want covered. Every additional sensor, camera, or keypad adds both hardware and labour time, so the jump from a 2-bedroom unit to a 4-bedroom house with a shed and side gate can easily double the quote.

Wired vs wireless matters less for price than most people expect — both start in a similar range. Wireless is faster and neater to install (no chasing walls or running cable through the roof), which is why most Perth installers default to it for existing homes. Wired tends to make more sense for new builds, where cabling can go in before the walls close up.

Business & Commercial Security System Costs

Commercial jobs price differently because they’re rarely “off the shelf” — a café, a warehouse and a multi-tenant office building all need very different coverage.

• Small office or retail alarm system: $2,000–$2,500 on average, sometimes as low as $600 for a minimal single-zone setup.
• Hard-wired commercial systems (multi-zone, integrated with access control or back-to-base monitoring): $2,500–$6,000+.
• Larger sites — warehouses, storage facilities, multi-building premises — can reach $4,000+ once you factor in perimeter coverage, multiple access points and integration with existing building systems.

If you’re running a fast-food outlet, storage facility, or franchise location, expect your quote to be shaped heavily by opening hours, cash handling, and whether the landlord requires a specific monitoring standard for insurance purposes.

CCTV Camera System Costs in Perth

CCTV pricing scales almost entirely with camera count and image quality:

• Entry-level 4-camera kit (4K, local NVR storage, no monthly fees): $1,200–$1,800 installed.
• Mid-range 6–8 camera system with proper cable runs and phone app setup: $2,200–$3,500.
• Commercial-grade 8–16 camera systems with AI-powered analytics (motion filtering, license-plate recognition, people counting) and access control integration: $4,500–$9,000+.

The jump between residential and commercial-grade cameras isn’t just marketing — commercial cameras are built for continuous 24/7 operation, wider dynamic range for harsh light (a real factor with Perth’s summer glare), and integration with monitoring centres and other security hardware.

Monthly Alarm Monitoring Costs

Monitoring is the ongoing cost most people forget to budget for. In Perth:

• Professional 24/7 back-to-base monitoring: roughly $25–$60/month, depending on response times and whether it includes visual verification.
• Cellular backup monitoring (so the alarm still reports if someone cuts your NBN line): usually adds $15–$25/month on top.
• Self-monitoring (alerts to your phone, no monitoring centre): can be close to free or a small cloud-storage fee, but there’s no guaranteed human response if you’re not looking at your phone.

Monitored systems are generally the better option if you want the alarm to actually result in someone being dispatched — and many home and business insurance policies offer premium discounts for a monitored system, which can offset the monthly cost over a few years.

Access Control & Intercom Costs

• Video intercom, single door: $650–$1,400 installed.
• Multi-apartment or commercial intercom/access control: priced per door/unit, and scales quickly — get a site-specific quote rather than assuming a per-door average.
• Keypad or fob-based access control for a single commercial entry typically starts in a similar range to a basic alarm system, with cost rising alongside the number of doors and users on the system.

What Actually Moves Your Price Up or Down

1. Property size and layout — more doors, windows and rooms mean more sensors and more labour.
2. Cable access — a home with clear roof access and short cable runs costs less to wire than one with double brick walls or a detached structure.
3. Camera count and resolution — each additional camera adds hardware, a cable run, and configuration time.
4. Monitored vs unmonitored — monitoring doesn’t change the install price, but it’s an ongoing cost to factor into your total.
5. Brand and equipment tier — prosumer gear (like entry-level CCTV kits) costs less than commercial-grade equipment with AI analytics.
6. Integration requirements — linking alarms, cameras and access control into one system costs more than three standalone systems.
7. Site complexity for businesses — multiple tenants, existing wiring, and compliance requirements (e.g. insurance-mandated monitoring standards) all affect commercial quotes.

How to Get an Accurate Quote (and Avoid the Lowball Trap)

The cheapest quote on paper isn’t always the cheapest system. A few things worth checking before you commit:

• Ask what’s actually included — some quotes cover hardware only and add installation, cabling or monitoring setup as extras later.
• Confirm the installer is licensed — in WA, security installers need to be licensed by WA Police. This isn’t optional, and it protects you if something goes wrong.
• Get the warranty in writing — manufacturer warranty and workmanship warranty are two different things; ask for both.
• Get 2–3 quotes for anything over $1,500 — the spread in this market is wide enough that comparing is worth the extra day.

Financing Options

Several Perth security providers now offer interest-free payment options through Zip or Afterpay for purchases over $1,000, which can make a full-coverage system more manageable if you’d rather spread the cost than pay it all upfront. Worth asking about directly when you get your quote, since not every installer advertises it.
