Home security can feel overwhelming if you're starting from scratch. There are cameras, alarms, smart locks, motion sensors, and full DIY kits — and the price range stretches from under $50 to several thousand dollars. The good news is you don't need to spend a fortune to meaningfully improve your home's security. You just need to know what you're buying and why.
This guide breaks it all down so you can make a confident decision without wading through tech jargon or getting upsold on features you don't need.
Step One: Work Out What You Actually Need
Before you look at a single product, spend five minutes thinking about your situation. The right setup for a standalone house in the suburbs is very different from what works in a flat, a rental, or a rural property.
Ask yourself:
- Do you own or rent? (Renters need non-permanent, easy-to-remove options.)
- What are the most likely entry points — front door, back door, garage, windows?
- Do you want to monitor things yourself via your phone, or do you want a system that contacts a monitoring centre?
- Are you mainly deterring opportunist theft, or do you have specific concerns like package theft or break-ins while you're travelling?
Your answers will shape whether you need a basic alarm, a camera or two, a full smart security kit, or a combination of all three.
The Main Types of Home Security Products
Security Cameras
Security cameras are the most popular starting point, and for good reason. A visible camera is a strong deterrent — most opportunist burglars will move on rather than risk being recorded. But not all cameras are equal.
Key features to look for:
- Resolution: 1080p is the minimum you should accept. 2K or 4K gives you sharper footage if you need to identify a face or number plate.
- Night vision: Most incidents happen in low light. Look for infrared night vision or colour night vision (better, but pricier).
- Field of view: A 130-degree wide angle covers much more ground than a narrow 90-degree lens. Important for covering driveways or large yards.
- Local vs cloud storage: Cloud storage means footage is saved offsite (often requires a subscription). Local storage saves to an SD card or hard drive on-site — no ongoing costs, but footage could be stolen with the camera if it's not hidden.
- Wired vs wireless: Wired cameras are more reliable but harder to install. Wireless (WiFi or battery) cameras are easier to place but depend on your network and battery life.
- Two-way audio: Lets you speak through the camera — useful for doorbell cameras and for deterring anyone approaching your property.
- Motion detection and alerts: Look for cameras with adjustable motion zones so you're not getting alerts every time a car drives past.

Alarm Systems
An alarm does two things: it alerts you (and potentially neighbours) when triggered, and it deters intruders from staying on the property. There are two main types available to most home buyers.
Standalone/DIY alarm kits are self-monitored. They sound a siren and send a notification to your phone. You decide what to do next. These are affordable, easy to install, and have no monthly fees. They're suitable for most NZ homes.
Professionally monitored systems connect to a monitoring centre that can dispatch a response when an alarm is triggered. These typically involve an installation fee and an ongoing monthly cost. They're worth considering for high-value properties, rural homes, or if you travel frequently.
For most people buying online, DIY alarm kits with app-based monitoring are the practical choice. Look for kits that include a base station, door/window sensors, and a motion sensor — these cover the most common entry points.

Smart Locks and Door Security
A significant number of break-ins happen through unlocked or easily forced doors. Smart locks add a layer of control — you can lock and unlock remotely, set temporary access codes for tradespeople or guests, and get alerts when your door is opened.
Things to check before buying a smart lock:
- Compatibility with your existing deadbolt or door hardware
- Whether it uses WiFi, Bluetooth, or Z-Wave (WiFi gives you remote access; Bluetooth-only works only when you're nearby)
- Battery life — most smart locks run on AA batteries and last 6-12 months
- Whether it still works with a physical key as backup
If you rent, look for smart locks that retrofit over your existing cylinder without replacing the lock body — these are landlord-friendly and easy to take with you when you move.
Smart Security Systems (All-in-One Kits)
Smart security systems bundle cameras, sensors, and sometimes smart locks into a single app-controlled ecosystem. They're designed to work together and are ideal if you want a more comprehensive setup without dealing with multiple apps or incompatible devices.
These typically sit in the mid-to-premium price range. The main advantage is convenience and integration — everything talks to each other. The main downside is you're locked into one brand's ecosystem, which can limit your options if you want to expand later.

Video Doorbells
Video doorbells have become one of the most popular home security additions in NZ, and it's easy to see why. They let you see, hear, and speak to anyone at your door — from your phone, anywhere in the world. They're also excellent for monitoring package deliveries and deterring door-to-door theft.
Look for: 1080p or higher resolution, motion detection with adjustable zones, night vision, two-way audio, and either cloud or local storage. Hardwired models are more reliable; battery-powered models are easier to install but need regular charging.
What Features Actually Matter (And What's Just Marketing)
Worth paying for:
- Reliable motion detection with customisable zones — reduces false alerts significantly
- Local storage option — no subscription fees, footage stays under your control
- Weatherproofing (IP65 or higher) — essential for any outdoor camera or device in NZ's variable climate
- Two-way audio — genuinely useful for deterrence and communication
- Strong encryption and two-factor authentication — your camera feed is private data; protect it
Don't stress about:
- 4K resolution for most applications — 1080p is sufficient for most homes; 4K uses far more storage and bandwidth
- Colour night vision — useful but not essential; standard infrared night vision does the job
- AI person/vehicle/animal detection — nice to have, but rarely a dealbreaker at entry-level
Red flags to avoid:
- Cameras with no weatherproofing rating marketed as outdoor cameras
- Systems that require a paid cloud subscription just to view live footage
- No mention of data encryption or security certifications
- Extremely cheap alarm kits with no app support or third-party integration
Price Ranges: What to Expect at Each Level
Under $100: Basic but functional
At this price, you can pick up a single indoor or outdoor camera, a basic alarm kit with door sensors, or a standalone siren. Good for renters, small spaces, or adding coverage to one specific area. Don't expect advanced features, but these products can still act as a solid deterrent.
$100–$300: The sweet spot for most homes
This is where you'll find quality standalone cameras with good night vision and cloud/local storage options, mid-range video doorbells, and entry-level DIY alarm kits with multiple sensors. Most NZ homeowners will find everything they need in this range.
$300–$600: Comprehensive coverage
Multi-camera systems, smart security kits with integrated sensors and locks, or higher-spec cameras with 4K resolution and colour night vision. Suitable for larger properties or anyone wanting a more complete setup.
$600+: Premium and professional-grade
Full smart home security ecosystems, professionally monitored systems, and commercial-grade cameras. Worth considering for high-value properties, businesses, or rural properties where response time from neighbours or police may be slow.
Installation: DIY or Professional?
The majority of home security products sold online are designed for DIY installation. Most cameras mount with two or three screws and connect to your WiFi in minutes. Alarm kits typically use adhesive mounts and magnetic sensors that require no drilling at all — ideal for renters.
That said, wired systems or anything requiring connection to your home's electrical wiring (like hardwired doorbells) should be installed by a qualified electrician in NZ. Don't risk it for the sake of saving a callout fee.
A Simple Starting Point for First-Time Buyers
If you're not sure where to begin, this setup covers the basics for most NZ homes without overcomplicating things:
- One outdoor camera covering your main entry point (front door or driveway)
- A basic alarm kit with door/window sensors for your most vulnerable entry points
- A video doorbell if package theft or door-to-door security is a concern
You can always build from there. Adding more cameras, interior sensors, or a smart lock later is straightforward with most modern systems.
