One of the first questions Perth homeowners and business owners ask us is simple: "What does a security system actually cost?" The honest answer is it depends - on the size of your property (we quote across Perth, Joondalup, Fremantle, Cockburn, Wanneroo, Rockingham and Mandurah), the number of cameras, whether you want monitored alarms, and whether you're choosing prosumer hardware like ReoLink or commercial-grade Dahua. This guide breaks down realistic 2025 prices so you can plan a budget before you call anyone.

CCTV Camera Installation

A typical residential CCTV install in Perth runs between $1,200 and $4,500 fully installed, depending on camera count and brand.

Entry-level ReoLink 4-camera kit (4K PoE): ~$1,200-$1,800 supplied and installed. Local NVR storage, no monthly fees, app access included.
Mid-range 6-8 camera ReoLink system: ~$2,200-$3,500 installed, including cable runs, NVR mounting and phone setup.
Commercial Dahua 8-16 camera system: ~$4,500-$9,000+ installed, with AI analytics, license-plate recognition and integration to access control.

Alarm System Installation

A standard wireless intruder alarm with 3-4 sensors, a keypad and a siren typically costs $900-$1,800 supplied and installed. Hard-wired commercial systems for offices, warehouses and retail run $2,500-$6,000+ depending on zones and back-to-base monitoring. Optional 24/7 monitoring is usually $30-$60/month through a third-party control room.

Intercom Systems

A single-door video intercom with a 7" indoor monitor typically lands around $650-$1,400 installed. Multi-apartment or commercial IP intercoms with mobile-app answering, electric strike integration and multiple stations range from $2,500 to $8,000+.

Video Doorbells & Access Control

A professionally hard-wired video doorbell (Ring or ReoLink) is usually $450-$850 installed, including the transformer upgrade most older Perth homes need. Standalone access control - keypad or RFID - for a single door starts around $900; networked multi-door access control with audit logs sits between $3,000 and $12,000+.

What Affects The Final Quote

Cable runs: single-storey brick is cheap; double-storey with no roof access adds labour.
Power location: needing a new GPO near the NVR adds an electrician's call-out.
Brand: ReoLink and Hikvision are excellent value; Dahua, Axis and Hanwha cost more but suit commercial.
Monitoring: back-to-base monitoring is a monthly fee, not a one-off install cost.
Warranty & support: our installs include a 3-year manufacturer warranty and a lifetime workmanship warranty, with no call-out fees in Perth metro.

What Cheap Quotes Usually Leave Out

When a quote comes in noticeably under the ranges above, it's almost always because something has been stripped out of the scope. The most common gaps we see when clients share competitor quotes with us:

No hard drive included. The NVR is listed but the surveillance-grade Purple drive that actually stores your footage is a separate $200-$400 add-on you'll be quoted for after install.
Grey-import hardware. Same-model cameras imported from overseas without local Australian warranty support. Firmware updates fail, cloud features are region-locked, and warranty claims mean shipping units back to China at your cost.
Battery cameras instead of PoE. Quoted cheaper because there's no cabling labour, but you'll be swapping or recharging batteries every 2-6 months and the cameras go dark every time.
No cable management. Cheaper quotes leave cabling surface-mounted in trunking rather than inside walls or eaves - functional but ugly, and the cable ages in the sun.
No app setup or handover. The install stops at "cameras working on the NVR." You're on your own for the phone app, motion zones, notifications and user accounts.

Payment, GST And Business Tax Treatment

For residential installs, prices in this guide are inclusive of GST for the standard consumer-facing quote. For business and commercial installs the ATO treats a security system as a capital asset with a depreciable effective life of around 5-10 years depending on the specific hardware - the installation labour typically depreciates over the life of the equipment. Most Perth SMEs claim the full cost under the instant asset write-off where the threshold applies. Talk to your accountant for the current year's limits and eligibility, but this is a legitimate deductible business expense in almost every case.

Financing And Payment Plans

For larger commercial installs ($5,000+) we can accommodate staged payments - typically 50% on site-visit sign-off, 40% on install completion and 10% on 30-day post-install check. For residential jobs the standard arrangement is payment on completion once you've walked the install and signed off. We do not lock you into a monthly service contract or subscription to keep the system running - once it's paid for, it's yours.

Ongoing Costs After The Install

Electricity: a typical residential CCTV + NVR runs on around 30-40W continuous, which works out to roughly $50-$80/year in Perth.
Hard drive replacement: $200-$400 every 5-7 years for the NVR surveillance drive.
Optional monitoring: $30-$60/month if you choose back-to-base alarm monitoring - can be discounted against home contents insurance.
Firmware and app updates: included free from the manufacturer for the life of the product.
Repairs during warranty: $0 - our lifetime workmanship warranty means we come back and fix any install-related fault at no charge, and the 3-year manufacturer warranty covers the hardware.
