Buying security cameras sounds simple until you start looking. One shop has a four-camera kit that costs less than a weekend away, another quotes for a full commercial setup, and every box promises crystal-clear footage. So how do you work out what actually matters?
The truth is that a good CCTV system isn’t about having the most cameras or the biggest numbers on the spec sheet. It’s about picking features that suit your property, whether that’s a family home in the suburbs, a retail shop or a warehouse with a big yard. A camera that’s perfect for a small section might be useless in a busy commercial car park.
At Action Security, we’ve been helping South Island homes and businesses with their security since 1981, so we’ve seen what works and what doesn’t. Here are the seven features we’d look at before buying security cameras anywhere in New Zealand.
Start with the picture itself. If the footage is grainy, it doesn’t matter how many cameras you’ve got. You need to be able to recognise a face, read a number plate or see what actually happened.
Most systems today come in Full HD (1080p), 2K or 4K. Higher resolution generally means more detail, which helps at entrances, driveways and car parks where you might need to zoom in on a recording later. Picture a shop owner reviewing footage the morning after a break-in. If she can’t make out the person’s clothing or the vehicle they left in, the recording isn’t much use to her or to the police.
Resolution isn’t the whole story, though. Here’s what else to look at:
One catch worth knowing. Higher resolution files are bigger, so they use more storage and more bandwidth. A 4K camera isn’t automatically the best choice. Often a good Full HD or 2K camera, placed well, does the job beautifully. If you’d like a broader walkthrough, we’ve also written a guide on how to choose the best security camera system for your property.
Trouble rarely waits for daylight. Whether it’s a tradie’s ute being targeted in a driveway or a back door at a café after closing, a lot of incidents happen in the dark, so night vision matters more than most people think.
There are a few ways cameras handle low light. Infrared night vision is the most common. The camera uses infrared LEDs to light the scene in a way you can’t see, and the footage usually comes out in black and white. Colour night vision works differently. It relies on ambient light, such as a street lamp or a porch light, or a built-in light on the camera itself, to record in colour when conditions allow. Colour footage can make it much easier to describe someone’s jacket or the colour of a car, which is the sort of detail the police will ask about.
Check the night vision range the manufacturer quotes, then compare it with your actual section. A camera rated for 30 metres is no help if the area you care about is 50 metres away, and a bright floodlight next to the lens can wash out the image.
Nobody wants to sit and watch a live feed all day. That’s where motion detection comes in. The camera notices movement, starts recording, and, if it’s set up for it, sends a notification to your mobile.
The trouble is that basic motion detection can’t tell a burglar from a branch. Wind, passing cars, a cat on the fence, and shifting shadows can all set it off, and after a week of pointless alerts most people stop looking at them. Better systems use person and vehicle detection, so you only hear about the things that matter. Imagine a family on holiday who get one alert because someone walked up to the front door, instead of forty because of a windy afternoon.
Useful settings to look for:
Business owners tend to value this most for restricted areas, like a stockroom or a back lane, where any movement after hours is worth knowing about. At home, it’s handy for gardens, side gates and entrances.
Being able to check in from anywhere is one of the best things about modern systems. With the right setup, you can open an app on your mobile, tablet or computer and see live footage, or wind back through recordings, without being anywhere near the property. A café owner can look in on the shop after locking up. A parent at work can see that the kids have arrived home safely. A business with two sites can watch both from the one screen.
Before you commit, check a few practical things. Find out whether the app works smoothly on your mobile and whether remote access is included or needs a monthly subscription. Your internet connection matters too, because live viewing needs decent upload speed. Rural properties can struggle here, so ask early. It’s also worth being able to set different access levels, so a staff member can watch live footage without being able to change settings or delete recordings. If you have questions about how this works day to day, our FAQs page is a good place to start.
A camera that records beautiful footage is pointless if you can’t find it when you need it. Where that footage is kept matters, and there are three common options.
The simplest is a memory card inside the camera. It’s fine for a small setup, but capacity is limited, and if someone steals the camera, they take the footage with them. A Network Video Recorder, or NVR, is the next step up. It’s a dedicated box that records from compatible IP cameras and keeps everything in one place, which makes it a sensible choice for larger homes and for any business with several cameras. Cloud storage sends recordings to an off-site server, so the footage survives even if the cameras or recorder are damaged. The trade-off is that cloud services often come with subscription fees, storage limits, and a reliance on your internet connection.
Whichever route you take, work through these first:
New Zealand weather doesn’t mess about. A camera on a Canterbury farm shed faces hot, dry summers and frosty mornings, while one on a Southland or West Coast house might cop rain sideways for days. Outdoor cameras need to cope with whatever your region throws at them.
The number to look for is the Ingress Protection rating, or IP rating. The first digit covers dust and the second covers water. Cameras rated IP65 or IP66 are commonly used outdoors because they’re built to keep out dust and resist water jets, though you should always check the product’s own specifications. A camera with no proper rating might be fine for a covered porch, but it’s a gamble out in the open.
Other things worth checking:
Placement helps too. Mounting a camera under an eave, for instance, can shield it from the worst of the rain while still covering the area you care about.
What you need today might not be what you need in three years. A couple of cameras at the front of the house can turn into six once you’ve built a garage or put in a studio out the back. A business that takes on a second building will want to add cameras without ripping everything out and starting again.
So ask whether the system can take extra cameras later, and whether the recorder has spare channels for them.
It’s also worth finding out how well the cameras work with other security gear. Depending on the brand and the setup, CCTV can work alongside intruder alarms, access control, video intercoms and central monitoring. A camera that fires up when the alarm trips, or a door entry system that shows you who’s at the gate on your mobile, adds a lot of everyday usefulness. Talk it through with a security professional before you buy, so you’re not left with equipment that won’t connect to anything else.
Knowing the features is half the job. The other half is thinking about what you’re actually protecting. At home, that usually means the front door, driveway, garage and back entry points. Commercial sites tend to need more, covering reception, the shop floor, stockrooms, car parks and loading bays.
Placement matters as much as the camera itself. A top-end 4K model mounted at a poor angle, or too far from the area you want to watch, will still give you disappointing footage. That’s one reason professional installation is worth considering. You’ll also need to decide between wired and wireless. Wired cameras give a dependable connection for permanent installations, while wireless ones offer more flexibility where power and connectivity allow. The right pick comes down to your building, your budget, and how you plan to use the system.
Picking the right equipment is only part of it. Who designs and installs the system matters just as much. Action Security is based in Christchurch and has been looking after residential and commercial customers across the South Island since 1981. That experience shows when it comes to working out where cameras should go, which features are worth paying for and which aren’t. We’ll look at your property, listen to what worries you, and recommend a system that fits, whether that’s a few cameras for a home or a larger setup for a commercial site. You can see everything we do on our services page.
Choosing security cameras comes down to a handful of things: clear video, reliable night vision, smart motion alerts, easy remote viewing, sensible storage, weatherproof construction, and room to grow. Get those right, and you’ll have a CCTV system that actually earns its keep, whether you’re protecting a family home, a shop or a workshop.
