Alarm Systems
DIY Alarm Systems
Wireless systems you install yourself — no professional installation required. Common brands in NZ: Yale, Bosch, Hikvision, and generic smart home systems (Tuya/SmartThings based).
Advantages: Low upfront cost, flexible placement, no installation fees.
Disadvantages: No professional monitoring unless you subscribe to a third-party monitoring service. Reliability and integration vary. If a break-in happens, you receive a phone alert — but no one is dispatched unless you have paid monitoring.
Best for: Renters, budget-conscious homeowners, properties where deterrence is the primary goal.
Professionally Installed Alarm Systems
Hardwired or semi-wireless systems installed by a licensed security company. Includes PIR motion sensors, door/window contacts, control panel, siren, and keypad.
Brands in NZ: DSC, Bosch, Paradox, Hills, Hikvision — installed by NZ security companies like Alarm Systems NZ, Paladin, Elcon, and many local security companies.
Advantages: More reliable than DIY (hardwired where possible), professional commissioning, monitoring available, insurance implications (see below).
What's typically included in a standard install (3-bed home): - 1× control panel - 1× indoor siren + 1× outdoor siren - 2–4× PIR motion detectors - 4–6× door/window reed switches - 1–2× keypads - Installation, wiring, commissioning
Monitored Alarm
A monitoring centre receives the signal when your alarm triggers and either attempts to contact you or dispatches a response (depending on your plan).
Response options: - Phone contact only: Monitoring centre calls you and your nominated contacts - Guard response: A security guard is dispatched ($80–$150 per callout, or included in higher-tier plans) - Police-linked: Alarm is connected to NZ Police via an approved monitoring centre. Requires an approved system installed by a licensed company and PSPLA (Private Security Personnel and Private Investigators Act) compliance
NZ Police response policy: NZ Police respond to monitored alarms linked through approved monitoring companies when specific criteria are met. False alarm charges apply after repeated false callouts — properly commissioned systems and user training reduce false alarms.
Smart/App-Connected Alarms
Modern alarm systems integrate with smartphone apps — arm/disarm remotely, receive push notifications, view activity logs. Many also integrate with smart locks, cameras, and home automation.
Brands: Yale, Ring, Ajax, and higher-end systems from Bosch or DSC with app connectivity.
Security Cameras (CCTV)
Standalone Cameras
Individual IP cameras — connected via your Wi-Fi or wired ethernet to your router. View footage via smartphone app or web browser.
Popular brands in NZ: Hikvision, Dahua, Reolink, Axis, Ubiquiti.
Resolution: 2MP (1080p) is the minimum useful resolution for facial recognition at close range. 4MP or 8MP (4K) for wider coverage where detail at distance matters.
IR night vision: Most modern cameras include infrared night vision — effective to 15–30m depending on camera. Colour night vision (uses visible light, requires some ambient light) provides better detail in low-light conditions than standard IR.
NVR/DVR Systems
Multiple cameras connected to a Network Video Recorder (NVR) or Digital Video Recorder (DVR) — stores continuous or motion-triggered footage locally on a hard drive.
Storage: A 1TB HDD stores approximately 30 days of footage from 4 cameras at 1080p with motion-triggered recording. 2–4TB for longer retention or more cameras.
Cloud backup: Some systems offer cloud storage as a backup in case the local NVR is stolen — monthly fee applies.
Doorbell Cameras
A video doorbell replaces your existing doorbell — shows who's at the door on your smartphone, records visitors, and deters package theft.
Ring, Reolink, and Eufy are the most common brands in NZ. Hardwired models (powered by your existing doorbell wiring) are more reliable than battery-powered; battery models need recharging every 1–3 months.
Licensing Requirements for NZ Security Installers
Under the Private Security Personnel and Private Investigators Act 2010 (PSPLA), anyone installing security systems commercially in NZ must hold a Certificate of Approval (COA) from the New Zealand Police.
What this means for you: - Any company or individual installing a security system for payment must be PSPLA licensed - You can check a company's licence via the Police's online PSPLA register - Unlicensed installers cannot legally connect your alarm to an approved monitoring centre
This also matters for insurance: Many NZ insurers require that alarm systems be installed by a licensed security company to qualify for a premium discount or for the alarm to count as a security feature.
Insurance Implications
Most NZ home insurers (AMI, State, Tower, Vero, AA Insurance) offer premium discounts for: - A professionally installed and monitored alarm system (typically 5–15% discount) - Deadbolts on all external doors - Security lighting
Check with your insurer before installing — some insurers specify brand or monitoring requirements. An alarm installed by an unlicensed installer may not qualify for the discount.

Frequently Asked Questions
How much does home security cost in NZ? A professionally installed alarm system (3-bed home, no monitoring): $800–$2,500. Monitored alarm (monthly fee): $30–$80/month. A 4-camera CCTV system (supply + install): $1,200–$3,500. Smart doorbell camera: $300–$800 installed.
Do I need a licensed installer for a home security system in NZ? For commercial installation (someone installing it for you for payment), yes — they must hold a PSPLA Certificate of Approval. DIY self-install of your own system is legal. Monitoring centre connection requires an approved monitoring company using licensed installers.
Do security cameras deter burglars in NZ? Research indicates visible security cameras and alarm boxes deter opportunistic burglars — NZ Police data suggests homes with visible security measures are less likely to be targeted. Cameras are most useful for evidence after an incident. Combine cameras with alarm systems and good lighting for the best deterrent effect.
What is the best home security system in NZ? For DIY: Yale, Ring, or Reolink systems offer good value and NZ support. For professionally installed: Bosch, DSC, or Paradox panels installed by a local PSPLA-licensed security company with monitoring. The monitoring component is important — an alarm that only sounds locally has limited value if no one is home to respond.
How do I connect my alarm to NZ Police? Through an approved NZ Police monitoring centre. Your security installer will arrange the connection as part of your monitoring agreement. Police response criteria apply — repeated false alarms result in removal from the response list.
