Use this checklist before hiring any security systems in Sydney, New South Wales.
- 1
Verify their electrical licence is current at your state's electrical safety authority (e.g. Energy Safe Victoria, NSW Fair Trading).
- 2
Confirm they carry public liability insurance of at least $5 million — ask to see the certificate.
- 3
Get 2–3 written quotes for any job over $500. A written quote protects both parties and clarifies the full scope.

Check their Google and TradeRefer ratings — look for consistent reviews mentioning punctuality, clean workmanship, and clear communication.

Frequently Asked Questions — Security Systems in Sydney
How much does a home security system cost in Australia?
Basic DIY alarm systems cost $200–$600 for hardware. Professionally installed systems cost $1,000–$3,500 depending on sensors, cameras, and features. Monitored alarm systems typically have ongoing monthly fees of $25–$60/month with a 3-year contract. Smart security cameras (Ring, Arlo, Eufy) cost $150–$500 per camera.
What is the difference between monitored and unmonitored alarms?
A monitored alarm connects to a 24/7 security monitoring centre that contacts you, nominated persons, and/or police when triggered. Unmonitored alarms sound a siren locally but don't alert anyone automatically. Monitored systems are preferred for insurance purposes and for unoccupied properties. Monitoring is typically $25–$60/month.
Are security cameras legal on residential properties in Australia?
Yes — security cameras on residential properties are legal for monitoring your own property. However, cameras must not be aimed at a neighbour's private areas (bedrooms, bathrooms, backyards). Signage indicating surveillance is recommended and required in some states. Recording audio requires consent from all parties in most Australian states.
Do I need a licence to install security systems?
In most Australian states, security system installation for commercial use requires a Security Technician or Electrical Contractor licence. For residential DIY systems, no licence is required for the homeowner. Hiring a company to professionally install a monitored system requires the company to hold an appropriate licence. Always check with state regulators.
What deters burglars most effectively?
Studies show the most effective deterrents are: visible alarm systems and monitoring signage, security cameras (especially visible ones), security lighting (motion-activated), deadbolts on all entry points, and an occupied appearance. Having multiple layers of security (camera + alarm + good locks) reduces risk far more than any single measure.
