Security systems don't have to come with hefty installation or monitoring fees—you can easily install DIY alarms and security camera systems on your own, like our top pick, the EufyCam 2C Security Kit. It catches our attention with high-quality equipment, theft-deterrent features, solid smart home compatibility and free local storage.

That depends on what type of DIY security system you're after. Simple alarm systems come with motion sensors, window/door sensors, and a central hub. Some come with a physical control panel, others can be controlled via a smartphone app. On the other hand, camera-based security systems come with cameras (surprise, surprise) and, depending on the brand, a Wi-Fi hub.
Another defining feature of DIY security systems is that, unlike many professional security systems, they're usually easy to add to. The following products are great starter kits, but you can always add additional sensors or cameras to the system down the line.
The EufyCam 2C Security Kit is easily our top pick for the best DIY security system overall. Why? Simple—it's an easy-to-setup, feature-packed product with solid smart home compatibility and free local storage at a decent price.
Each camera boasts HD video, a truly wireless design, a bright spotlight for clear, colour night vision, and a motion-triggered alarm to deter would-be thieves. There's also two-way audio that allows you to chat to any visitors.
The only downside is that this system has been superseded by a newer model, the EufyCam 3C. The 3C comes with 4K resolution and the new HomeBase 3 (which has expandable storage), however, it will set you back twice the price of the 2C. For that reason, we're still recommending the 2C.
Alarm, spotlight and two-way audio
Completely wireless
Free local storage
Smart home compatibility 
Expensive
Doesn't include latest HomeBase model These cameras are built to withstand whatever the weather throws at them and can be used inside or outdoors, and because they're wireless, installation is a cinch. They can operate on a single charge for up to six months, otherwise, you can add compatible solar panels so you won't have to worry about low battery notifications again.
For those looking for a security camera system that meshes seamlessly with your smart home setup, you'd struggle to find something better than the EufyCam 2C. Out of the box, it works with Google Assistant, Amazon Alexa, and Apple HomeKit. That said, it is the priciest pick on our list.
The TP-Link Tapo C420S2 Wire-Free Camera System is one of the best value security camera systems in Australia. For just under $300, you get a wireless, weatherproof 2K camera, plus a hub, which can be used to build a fully decked-out smart home system.
We really like that this system includes local storage capabilities (which means no pesky subscription fees) and its IP65 waterproofing rating means you can install the cameras just about anywhere.
On the downside, the battery life isn't the best we've ever seen, however, there is a solution. The Tapo C420S2 is compatible with Tapo's solar panels, meaning you can keep your cameras fully charged. Solar panels can be purchased for as little as $45 per camera, which is quite cheap compared to other brands.

Comparatively narrow field of view The Eufy Security Home Alarm Kit is a perfect starting point for those wanting to protect their home on a budget. Although it lacks compatibility with smart home setups like Google Home and Amazon Alexa, it can still be monitored remotely via the Eufy Security app, which can also send real-time alerts straight to your phone.
Included in the kit is one motion sensor, two entry sensors (for windows or doors), the HomeBase hub, and a keypad for arming and disarming without needing to go through the app—though you can do so if you wish, even if you're not at home.
Eufy is well-known in the DIY home security space, meaning there are tons of affordable add-on products available should you wish to expand your security system. These include cameras, video doorbells, smart locks, and more.
Easy installation
Remote arm/disarm
Includes keypad and hub
Affordable add-ons
No smart home compatibility
Doesn't include latest HomeBase model If you're on a serious budget but still need some sort of alarm system for your home, it's hard to go past a good ol' fashioned contact sensor. And at less than $40 for five of them, the Daytech Window/Door Alarms offer stellar value.
They're a breeze to install (simply stick them on your doors or windows and they're ready to go) and easy to use, thanks to the controls on the plug-in receiver, which allow you to choose between 55 chimes, 5 volume levels and a mute mode.
Of course, being so simple they do lack the features you'd find on a kit like the Eufy system above. There's no accompanying app, no way to control the alarms remotely. But at a price that good, who could say no?
Very affordable
Loud
Simple to install
55 chimes
Very limited features
No remote control ability The EufyCam 2C Security Kit is our favourite DIY home security system overall, combining smart home tech with traditional security system features for a reasonable upfront price and no ongoing monthly fees.
As for those who don't need (or want) any fancy cameras, the Eufy Security Home Alarm Kit will serve you well with its remote connectivity and buildability.

Most DIY security systems come with free companion apps that guide you through installation and allow you to control your system remotely.
Most DIY systems are easy to set up and can move with you, making them great for renters. The simple assembly makes for easy disassembly when you pack up to move out, which is convenient for renters.
Generally, DIY systems come with peel-and-stick sensors that attach directly to the wall. They are usually easy to remove, and you can replace the adhesive in your new place.
At most, you'll need a screwdriver to pop open battery cases or remove equipment from the wall.
Your house size determines how many contact sensors you'll need. At a minimum, you should have a door and window sensor at each main entry point—exterior doors and easily accessible windows. This may mean only one contact sensor if you live in an apartment or dozens if you have a larger house with multiple exit points.
Pets under 25 kg generally don't trigger motion detection. For dogs over 25 kg, you can replace the motion sensor with a glass break sensor or security camera.
Not usually, but some systems may be compatible with Z-Wave technology that allows allow you to customise your home with third-party smart home products like smart bulbs and outlets. For security products, however, it's best to stick within the one brand.
Hacking is a risk every user takes when using any internet-connected wireless system.
