How to create a home security system on a budget: affordable bundles to keep you safe

In an ideal world, we'd all be able to lock down our homes with no chance of unwanted guests entering, but until fairly recently, such security was out of reach for most people. These days home security systems are more affordable and often completely DIY, removing the barrier to entry even more. The best home security systems (opens in new tab) consist of various smart home devices (opens in new tab), from the best security cameras (opens in new tab) to contact sensors and more.

They're also very easy to add to and expand over time, so if you want more outdoor cameras or a smart lock (opens in new tab), they're often easy to integrate into your existing system.

If you have an Alexa or Google Assistant speaker in your home, then a smart security system is the way to go. Connecting the two will let you receive alerts and give voice commands - useful for when you don't have your hands free. The best smart displays (opens in new tab) will allow you to view a live stream of your chosen area to keep an eye on things.

This article will focus on DIY home security systems that don't generally need professional installation. Not only does this keep costs down, but it also means that anyone in any home can install one. First, you should decide what components you will get the most out of, which will help you choose the best home security system for you.

What do you need?

It may 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 various compositions, from camera-centric to single-device alarms. If you're looking for something below £300 / GBP250 / AU£450, you'll likely get the basics of a contact sensor, motion sensor, home base, and security camera, but it varies. Security camera

Security cameras are probably the element of a DIY system that 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 are usually best mounted to a wall for the best view. Motion sensor

Motion sensors do what they say on the tin and detect when someone or something is moving in an area of the home. This is useful for detecting break-ins when you're away, and they can often be configured to ignore pets. Contact/door/window sensor

Attach these to a door or window, and you will be alerted when they are opened. 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 sensor, glass break sensor and smoke alarm sensor

Slightly more advanced options, these sensors can be placed in the relevant areas to avoid missing faults in plumbing, a smoke alarm alert, or a window breaking. Keypad & app While most modern smart security systems make it easier to use the app for things like shutting off alarms and monitoring events, some will also provide a keypad for times when you aren't actively using your phone.

Homebase/alarm Many home security systems fold their siren or alarm into the home base, which should be placed in a convenient location where you are most likely to hear it (or shut it off when there's a false alert), like the living room.

Are you a renter or a homeowner?

What you can do with things like outdoor security cameras and smart alarms may differ significantly depending on whether you own your home or you are renting.  If you don't have permission from your landlord, you might not want to drill holes into your wall or permanently attach anything.

Thankfully, most home security systems can be installed using removable tape. We recommend checking what's included to see if it would be the most suitable for your situation. Homeowners, meanwhile, have a little more choice. 

Upfront cost or subscription?

While we're looking at keeping the upfront cost of purchasing a security system low, you should also keep an eye out for hidden subscription costs that often come with these DIY security kits.

We've outlined the total costs below, with top brands charging between £12.99 and £22 for premium features. So, remember that even if you get a bargain on the kit itself, things can still get expensive.
