Commodore Security — Security Systems in Castle Hill

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.

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.

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.

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.

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.
