Best home security systems in 2023: The top smart alarms to protect your home
The safety and security of our property has always been a top priority for homeowners, but the advent of home security systems has revolutionised the way we protect our living spaces. It’s now even easier to ensure our homes are protected from threats and hazards.
Home security systems offer numerous benefits extending beyond simply protecting from intruders. These advantages include sending emergency service alerts, smoke detection, enhanced energy management, and improved neighbourhood safety.
Our experts have delved into the complex world of home security systems, exploring and testing the features, benefits, and the latest technological advancements that have elevated them to new heights.
90-second read
In testing and comparing home security systems, our researchers considered multiple factors, including price, installation, and features.
In general, we found that most systems are easy to install yourself with minimal effort required, with some suppliers offering the option of professional installation for a fee. produced the only system that required professional installation, which came at an additional cost, as did the professional monitoring. However, if you want this level of monitoring, ADT’s alarm package is well worth considering.
We found that SimpliSafe’s The Tower package offered the best overall service and, despite its mid-range price point, the package includes everything you need to set up an efficient smart home security system. While it has a subscription-based professional monitoring option, with multiple alerts and a user-friendly app, self-monitoring is a viable, cheaper, option.

What is smart home security?
Smart home security refers to an integrated system of interconnected devices designed to deliver a comprehensive and user-friendly solution for protecting homes from potential threats, such as intruders, fires (with connected smoke alarms and smoke detectors), and other safety hazards.
Typically, the systems include surveillance cameras, motion detectors, and burglar alarm systems, which can be controlled and monitored remotely using smartphones or other devices. Homeowners can programme their system to follow specific routines or react to certain triggers – sending an alert when a door is opened or when motion is detected, for example.
Additionally, some home security systems integrate with other smart home technologies, such as lighting or heating, creating a more cohesive and secure living environment.

SimpliSafe offers a range of preconfigured packages, all of which can be fully customised to suit your requirements. For the average three-bedroom semi-detached property, The Tower needs no additional components and is ready to go once the base station is plugged in, combining internal and external cameras, a motion detector, door and window sensors, and an integrated keypad. While The Tower is one of its pricier options, SimpliSafe frequently has steep product discounts, making options, such as this package more affordable.
Simplisafe users can choose between self-monitoring or professional monitoring, with two flexible monitoring plans available starting at 53p per day.
We found the peel and stick sensors incredibly straightforward to install, with no drilling required and comprehensive connectivity instructions. The system was also easy to set up using the dedicated app.
The hardware is sleek and stylish, available in obsidian or white, and incorporates a stylishly contemporary pear-shaped base station. This glows with a steady blue light, and pulses if there is an error in the system.
With the SimpliSafe app, you can access and control your security system remotely via user-friendly smartphone or tablet interfaces. The app allows you to arm or disarm your system, view live camera feeds, and receive instant notifications in the case of a security event. The system uses end-to-end encryption to protect data, ensuring personal information and video feeds remain secure and private.
All of Simplisafe’s packages are compatible with smart home ecosystems Amazon Alexa and Google Assistant. This allows you to control your security system using voice commands.
While the indoor camera lacks the ability to pan or zoom, with a 120-degree lens it already covers an expansive area. Both the picture quality and sound are easily distinguishable, and even the night vision is clear. The motion detection uses heat signatures to differentiate between a pet, a person and an object (a thrown ball, for example), minimising false alarms.
If you take out one of the monthly subscription plans, you’ll benefit from the 24/7 professional monitoring. In case of any security concerns, with the more advanced monitoring package the SimpliSafe monitoring centre is notified, and they can dispatch emergency services to your location.
Our verdict
While SimpliSafe’s The Tower package provides an excellent home security solution, the initial cost may be prohibitive for some homeowners. However, considering the monitoring plans’ quality, features, and flexibility, we believe it is a worthwhile investment in the long run.

ADT has been a trusted name in home security for many years, and its Smart Home Alarm Package demonstrates its commitment to evolving with modern technology. This comprehensive security system combines traditional ADT reliability with smart home features.
Although we tested the Smart Home Alarm Package, like many security systems, the company’s accessories and packages can be fully tailored to your requirements with additional elements incorporated into the system.
It features a touchscreen control panel that serves as the command centre for your system, and allows you to arm and disarm the system, control smart home devices, and view live video feeds from the cameras. With an 8MP camera incorporated, it automatically captures a picture of the last person who disabled your alarm.
The ADT+ App also allows you to manage your home security remotely, and the security company plans to integrate controls for third-party smart home products that use Matter, enabling control of compatible smart lights, thermostats and other smart technologies.
With efficient contact sensors to detect when entry points are opened or closed, passive infrared (PIR) motion detectors that sense movement and ignore any household pets, and a wireless key fob that includes a panic button for emergencies, ADT appears to have every base covered.
The security system is designed for professional installation, ensuring it’s set up correctly and functioning optimally. Upon purchase, ADT will schedule a technician to visit your home and install the devices. This process may take a few hours, depending on the size and complexity of your home.
ADT offers 24/7 phone support, email support, and live chat, in addition to their online help centre, but our researchers found the customer support team didn’t always know the answers to our questions and took up to 10 minutes to get through. The live chat provided quicker responses.
Your standard subscription includes access to the ADT Remote Operating Centre, which automatically conducts daily system checks, ensuring every device runs optimally. Most technical issues can be dealt with remotely. Depending on the subscription level you choose, you, your keyholders, the police, or a private security guard will be notified in the event of a security breach.
Our verdict
The ADT Smart Home Alarm Package offers an advanced security solution that combines home automation and comprehensive protection. While the higher cost and long-term contract may be a drawback, the system’s reliability, professional installation, and seamless integration with smart home platforms makes it an attractive choice for those looking for a high-quality and professionally monitored home security solution.

How much should you pay for a smart home security system?
The cost of a smart home security system can vary greatly depending on the brand, features, components, and level of professional monitoring you choose. Prices can be anywhere from around £150 for a self-monitored, self-installed system, to several hundred pounds with ongoing monthly costs for a professionally installed and monitored home security system.
What to consider when buying a smart home security system
When buying a smart home security system, there are several factors to consider to find the optimal solution for your needs.
- Think about your property’s size, entry points and any potential vulnerabilities to help determine the type of system you require and what additional features are necessary, such as motion detectors and smart locks
- If you already have smart home devices, such as lighting, thermostats and voice assistants, a system that’s compatible with those would help to create an integrated environment
- Some smart home security systems can be easily installed by anyone who has a basic knowledge of DIY, while others may require professional installation. Decide if you’re comfortable fitting the system yourself or would rather pay someone to do it for you
- If you want a self-monitored system, a mobile app with a user-friendly interface is essential. This allows you to receive notifications and easily manage your system. Professionally monitored systems typically include a monthly subscription, which can be costly, but it will automatically alert emergency services on your behalf
- Decide on the budget for your system, which should factor in the cost of the devices, installation, and any ongoing subscription fees for monitoring or cloud storage
How to install a smart home security system
Installing smart home security systems can be a straightforward process, especially if you choose a DIY-friendly option. Manufacturers should include instructions and guidelines with their systems as the installation process differs depending on your brand and type, and you should read these first.
Generally, however, the installation for most systems follows these steps:
Plan your system
Before installing, carefully plan the placement of each component, including the cameras, motion detectors, sensors and central hub. You should consider which areas of your home you want to monitor most closely and the range of the sensors and cameras you have chosen.
Set up the central hub
The central hub, or base station, is the heart of your system and is designed to connect all of your security devices. If possible, place it in a central location within your home, and the manufacturer should provide instructions to connect it to your wifi network.
Install the cameras
The cameras should be installed in positions that cover entry points and high-traffic areas, yet within wifi range of your central hub. Most cameras can be mounted using adhesive strips or screws and, once fixed in place, should be connected to the central hub according to the instructions.
Install the door and window sensors
Make sure the two parts of a door and window sensor align when closed, and then attach the first part of the sensor to the frame and the second to the opening section of the door or window. That way, the sensor can detect when it is opened and alert the home alarm system
Install the motion detectors
The motion detectors should be located in areas in which you want to detect movements, such as large rooms and hallways. The manufacturer’s instructions should include the optimum mounting height and angle and how to connect them to the central hub.
Install the smart locks
If your system includes smart locks, follow the manufacturer’s instructions to replace your existing locks with the smart locks. Ensure that your door is compatible with the smart lock you’ve chosen.
Configure your system
Once each component is installed, the accompanying mobile app can be used to configure the settings for your security devices, such as motion sensitivity, camera recording preferences, and alert notifications.
Testing your system
Triggering each sensor, checking camera feeds, and testing any other component, will confirm that your system is connected and communicating correctly with the central hub.
Set up monitoring and automation
If your system includes monitoring services or smart home automation features, these can be managed through your mobile app.
Smart vs traditional alarm systems
Both traditional and smart alarm systems are designed to protect homes from intruders and other threats; however, they differ in functionality and features.
Smart security home alarm systems
Smart systems use wifi technology to integrate various components, such as surveillance cameras, motion detectors, and sensors, to provide a comprehensive security solution. Connected to the internet via a central hub (using wifi or ethernet), they allow remote monitoring, real-time notifications, and customisation through your mobile phone.
Using your mobile app, you can arm, disarm, and check the system’s status from anywhere with an internet connection.
Many smart systems include detectors for smoke and carbon monoxide leaks. They can also be integrated with other smart home devices, such as lights and thermostats, allowing for a more efficiently managed home.
This advanced technology is generally more expensive than traditional home alarm systems and may require a monthly subscription for professional monitoring or premium features.
Traditional alarm systems
Traditional systems are not wifi-enabled and instead rely on a landline or cellular connection for communication. As a result, remote access is nonexistent, meaning that real-time notifications through smartphone apps are unavailable. Typically, traditional systems use audible alarms and contact a monitoring centre in the event of a security breach.
Traditional systems often require a contract for professional monitoring, but the subscription fees may be lower compared with smart security systems, especially if you choose a basic package.
Can a smart alarm be hacked?
Like any other internet-connected device, smart security systems can be hacked. Their reliance on wifi connectivity for system components, such as motion sensors and cameras, makes their signals vulnerable to interception. Thankfully, even though hacking is possible, it’s not necessarily probable.
In order to breach your particular security system, a hacker must have sufficient knowledge about your technology and its security configurations to select an appropriate method. Additionally, the hacker would require access to your home’s wireless network, necessitating a distinct set of expertise and resources.
However, there are some simple measures you can take to protect your security system from potential hacking attempts. These include:
- Strong passwords: Use unique, complex passwords for your smart home devices, security system, and wifi network. Regularly update your passwords and avoid using easily guessable information
- Two-factor authentication: Enable two-factor authentications for your smart home devices and accounts whenever possible. This adds an extra layer of security by requiring a verification code and your password
- Robust encryption: When choosing your smart home security system, selecting one with strong encryption prevents your information falling into the wrong hands. Most systems use end-to-end encryption. This is a method of secure communication that stops third parties accessing your data while it’s transferred from one end system to another, eg from your indoor and outdoor security cameras to the home hub. It scrambles your information, turning it into indecipherable code.
- Regular updates: Ensure your smart home devices, security systems, and routers are up-to-date with the latest software updates. Updates often include security patches that help protect against known vulnerabilities
