DIY vs Professional Installation
DIY wireless systems (Ring, Arlo, Swann): - Lower upfront cost, no installation fee - Adequate for deterrence and self-monitoring - Rely on WiFi — can be disrupted by power outages or WiFi jamming - Insurance discounts usually smaller than professionally certified systems
Professionally installed systems: - Hardwired sensors don't rely on WiFi - Tamper-evident, properly certified - Required by some insurers for premium discounts (ask your insurer) - Installation by a licensed security technician - Better integration with monitoring centres
For most NZ homes, a mid-range professionally installed wireless system ($1,000–$2,000) with a monitored response service is the practical sweet spot.
Insurance Premium Discounts
Most NZ home insurers offer discounts of 5–15% for monitored alarm systems. For a $3,000/year home insurance premium, a 10% discount saves $300/year — which offsets monitoring fees and can justify a better system over 3–5 years.
Check with your insurer before purchasing — some specify certified systems (Grade 2 or higher) for the discount to apply.
What NZ Burglars Actually Look For
Police data on residential burglaries consistently shows: - Unlocked entry points — windows left slightly open, unlocked doors - Concealed entrances — overgrown hedges and dark yards - No visible alarm/camera presence — the sight of cameras and an alarm box is a deterrent - Signs of absence — mail buildup, no lights at night, consistent empty-looking property
Visible camera presence and a monitored alarm sign on the fence are among the most effective deterrents, regardless of whether the underlying system is basic or premium.
