How to Build a Home Security System on a Budget

In an ideal world we would all be able to lock our homes with no chance of unwanted guests entering, but until fairly recently such security was out of reach for most people. Home security systems these days are more affordable and often completely homemade, further removing the barrier to entry.

What do you need?

It might be tempting, but you probably don’t need a 30-piece security set when you live in a two-bedroom house. Home security systems come in different builds, from camera-centric alarms to single-device alarms. If you’re looking for something under $300 / £250 / AU$450 you’ll probably get the basics of a contact sensor, motion sensor, home base and security camera , but it varies.

Security camera

Security cameras are probably the piece of a DIY system we’re all most familiar with and many people often opt for a single camera over a more elaborate setup. These cameras can be used indoors, outdoors, or both, and it’s usually best to mount them on a wall for the best view.

Motion sensor

Motion detectors do what they say on the box and detect when someone or something is moving in an area of ​​the house. This is useful for detecting break-ins when you’re away, and they can often be set to ignore pets.

Contact/Door/Window Sensor

Attach them to a door or window and you’ll be alerted when they’re open. The devices come in two pieces, one attached to the frame and the other to the window/door itself, so it can tell when these two parts are separated.

Leak detector, glass break detector and smoke detector

Slightly more advanced options, these sensors can be placed in relevant areas to avoid missing plumbing faults, a smoke detector alert, or broken glass.

Keyboard and app

While most modern smart security systems make it easy to use the app for things like silencing alarms and monitoring events, some will also provide a keypad for times when you’re not actively using your phone. .

Base/Alarm

Many home security systems tuck their siren or alarm into the home base, which should be placed in a convenient location where you’re most likely to hear it (or turn it off in the event of a false alarm) , like the living room.

Are you a tenant or owner?

What you can do with things like outdoor security cameras and smart alarms can differ significantly depending on whether you own your home or rent.

If you don’t have permission from your landlord, you may not want to drill holes in your wall or fix anything permanently. Fortunately, most home security systems can be installed using removable tapes. We recommend checking out what’s included to see if it would work best for you.

Owners, meanwhile, have a bit more choice.

Initial cost or subscription?

While we aim to keep the initial cost of purchasing a security system low, you should also keep an eye out for the hidden subscription costs that often come with these DIY security kits. We’ve outlined the total costs below, with major brands charging between $12.99 and $22 for premium features. So remember that even if you get a good deal on the kit itself, things can still get expensive.
