Home Security Cameras NZ: How to Choose (Wired, Wireless, Cloud or Local)

Choosing security cameras in NZ comes down to two decisions: how each camera gets power and data (Wi-Fi, a battery or one Ethernet cable) and where its video is stored (a microSD card, a hub or recorder inside the house, or the cloud). For most homes, two to four plug-in Wi-Fi cameras recording locally are the sweet spot, at roughly $60 to $120 a camera with no subscription.

This guide is for homeowners, renters, lifestyle-block owners and small businesses working out what to buy. It covers system types, storage, features, installation and privacy rules, and includes a calculator to size your hard drive. For brand-specific advice, see our guides to Tapo cameras, eufy’s no-subscription systems and Arlo. If you also want door sensors and a siren, read our guide to smart home security systems.

Which security camera system suits you?

Most setups fall into one of four types, and plenty of homes mix two, such as Wi-Fi cameras inside and a wired camera covering the driveway.

Wireless security cameras

A wireless security camera in NZ usually means a camera that joins your home Wi-Fi, whether it plugs in or runs on a battery. Setup takes minutes in a phone app and most record to a microSD card. The weak point is the Wi-Fi itself: most cameras use 2.4 GHz only, brick veneer and foil-backed insulation weaken the signal outside, and a congested network can drop footage. Tapo models start under $60; eufy and Arlo cost more but add features such as home hubs, 4K sensors or longer battery life.

Battery and solar cameras

With no cables at all, battery cameras suit renters and spots far from a power point. The trade-offs are that most record short motion clips rather than 24/7, can miss the first moment of an event while they wake, and need recharging every few weeks or months depending on how busy the spot is. A solar panel helps, but low winter sun is a real limit in the south, as our guide to solar cameras in an NZ winter explains.

Wired PoE (CCTV) camera systems

A PoE camera system is what installers now mean by CCTV: IP cameras each connected by one Ethernet cable that carries both power (Power over Ethernet) and video to a network video recorder with a hard drive inside. These systems record 24/7, don’t depend on Wi-Fi and keep recording if the internet drops. As a price guide, Reolink’s NVS8-8MD4 kit (four 4K cameras, an 8-channel NVR and a 2 TB drive) was listed at $1,299 at Harvey Norman in September 2026.

The work is in the cabling: each camera needs a Cat 5e or Cat 6 run back to the recorder or a PoE switch, usually through the ceiling space. Our guide to choosing a network switch explains PoE power budgets if you are adding cameras to an existing network, and UniFi Protect is worth a look if you already run Ubiquiti gear.

Hikvision and Dahua are two of the world’s biggest CCTV makers, and their hardware is also sold under other brand names. Both have been restricted by some overseas governments on security grounds, so whichever brand you choose, keep the recorder off the open internet and install firmware updates.

NVR vs cloud vs microSD: where your footage lives

Storage decides your running costs and what happens if a burglar takes a camera.

Local recording wins on cost and privacy. Hide the recorder in a cupboard or ceiling space so it can’t be carried off, and put it on a small UPS so a power cut doesn’t end the recording. If you already run a NAS, most models can record cameras too (Synology’s Surveillance Station is one example), and our NAS storage guide explains the hardware.

Cloud recording keeps a copy off-site, which matters when the camera itself is at risk. The cost adds up: in NZ, Arlo Secure costs $7.99 a month for one camera, $14.99 a month for unlimited cameras, or $19.99 a month for the Plus plan with person and vehicle recognition. Three years of the unlimited plan is about $540, often more than the cameras. Cloud clips also use upload bandwidth, and a typical Fibre 100 plan uploads at 20 Mbps.

A sensible middle path is local recording for every camera, plus a cloud plan only on the one or two cameras a thief could reach.

How much storage do your cameras need?

Storage depends on bitrate, the amount of data each camera produces per second. Recording 1 Mbps around the clock uses 10.8 GB a day, so a camera’s resolution, codec, frame rate and recording mode drive the size of drive you need. Plug your own numbers into the calculator.

As a worked example, four 2K (4MP) cameras using H.265 at 15 fps average about 2.4 Mbps each, or 26 GB per camera per day. Keeping 30 days of 24/7 footage takes about 3.1 TB, so a 4 TB drive fits with headroom. Switch the same cameras to motion-only recording with around three hours of activity a day and the total drops to roughly 390 GB.

What to look for in a home security camera

Resolution and detail

2K (4MP) is the sweet spot for most home cameras. 4K helps on wide views where you want to zoom in on a face or number plate, but it roughly doubles storage and upload needs. Resolution alone doesn’t decide detail: a narrow lens aimed at the gate shows more detail there than a wide 4K lens covering the whole section. Our outdoor camera guide has a coverage calculator that works out pixels per metre at a given distance.

Night vision

Standard infrared gives black-and-white footage to roughly 10 to 30 metres, depending on the model. Starlight sensors and built-in spotlights give colour at night, and a spotlight doubles as a deterrent. Infrared reflects off glass, so never aim a night-vision camera through a window.

Smart detection

Person, vehicle and pet detection cut the false alerts caused by trees, cats and headlights. Check where it lives: Tapo includes it free, while Arlo keeps person and vehicle recognition for its Plus plan.

Weatherproofing

Look for IP66 or IP67 on anything outside. Neither rating covers salt air or UV, so coastal homes should favour models with metal housings, mount cameras under eaves and use stainless fixings.

Local access and integrations

Cameras that support RTSP or ONVIF can record to almost any NVR, NAS or Home Assistant setup, which keeps you from being locked into one app. Most PoE cameras and many plug-in Wi-Fi cameras (including Tapo) offer this; battery cameras generally don’t.

Best home security cameras in NZ by situation

Security camera installation in NZ

Plug-in, battery and solar cameras are straightforward DIY jobs: a drill, a ladder and the app. PoE cabling is also low-voltage work many people do themselves, though working in a ceiling space means watching for old wiring, insulation and nails.

Mains power is different. WorkSafe says homeowners who own and live in a property can do some electrical work themselves, but they can’t connect it to the supply; a licensed electrical inspector has to check and connect it. In practice, a new outdoor power point for a camera is a job for an electrician. PoE avoids the question, because power comes down the data cable from the recorder or switch.

If you pay for installation, ask where the recorder will be hidden, what cable is used, whether the cameras support ONVIF (so you are not locked into the installer’s app) and who looks after firmware updates.

Security cameras and the Privacy Act

At home, the Office of the Privacy Commissioner’s guidance on CCTV at home says the Privacy Act generally doesn’t apply to individuals filming their own property, unless the filming would be highly offensive to a reasonable person, such as looking into a neighbour’s bathroom. Images of what is visible from the street aren’t treated as highly offensive. It recommends talking to neighbours first, putting up a sign, not aiming cameras at neighbours’ windows or private areas, not keeping footage longer than you need and never posting neighbours’ footage on social media. If a camera records a crime, give the footage to Police rather than sharing it online.

Businesses, landlords filming common areas and other organisations are covered by the Act. The Commissioner’s CCTV guidance for organisations expects a clear purpose before installing, signs saying who operates the cameras and how to contact them, no audio recording unless it is really needed, secure storage with a set retention period, and a process for people who ask for footage of themselves.

Common mistakes to avoid

• Buying on megapixels alone. Lens angle, night vision and placement matter as much as resolution.
• Ignoring running costs. A cheap camera with a monthly plan can cost more over three years than a dearer one without.
• Relying on weak Wi-Fi. Check the signal at each mounting spot on your phone before drilling, or run a cable.
• Leaving the recorder exposed. Hide it, and don’t open ports on your router to reach it; use the maker’s app or a VPN.
• Never testing at night. Look at the live view after dark before you finish, as glare, spider webs and porch lights all ruin night footage.

FAQs

What is the best home security camera in NZ?

For most homes, a 2K Wi-Fi camera with free local recording gives the best value, such as a Tapo C210 indoors (about $59) or a C520WS outside (about $113). For whole-property 24/7 coverage, a wired PoE system with an NVR is more reliable.

How much does a security camera system cost in NZ?

Plug-in Wi-Fi cameras start at about $35 each, battery and solar cameras run from about $110 to $500, and a four-camera 4K PoE kit with a recorder costs around $1,300. Professional installation and any cloud subscription are extra.

Do security cameras need Wi-Fi or internet?

No. PoE cameras connect by cable, and most cameras keep recording to a card, hub or NVR when the internet drops. You need internet only for alerts, remote viewing and cloud storage.

Is an NVR better than cloud storage?

An NVR records 24/7 with no monthly fee and keeps footage private, but it must be hidden so a burglar can’t take it. Cloud storage keeps an off-site copy and suits battery cameras, at a cost of NZ$7.99 to $19.99 a month for Arlo’s plans.

How long should I keep security camera footage?

One to four weeks covers most home needs, since incidents are usually noticed within days. The Privacy Commissioner advises keeping footage only as long as you need it, and businesses should set a fixed retention period.

Is it legal to have a security camera facing the street in NZ?

Yes, generally. The Privacy Commissioner says images visible from the street aren’t highly offensive, but you should avoid filming neighbours’ private areas, use signs and never post their footage online.

Can I install security cameras myself in NZ?

Yes. Plug-in, battery and PoE cameras are fine for DIY, but a new 230 V power point needs an electrician, or inspection and connection by a licensed electrical inspector if you do the wiring yourself as an owner-occupier.
