Buying a home alarm: how to choose the right one
Summary
Protecting your home starts with choosing the right alarm system for your needs. In this helpful guide, the Verisure team explains the differences between wired, wireless, smart, and monitored alarms, and what features truly matter. Discover how professional monitoring from Verisure offers round-the-clock protection and complete peace of mind.
Your home is more than a building; it's a place where you should feel safe and secure. While burglary rates have fallen over the past decade, the risk hasn't disappeared. Nearly 400,000 households in England and Wales experienced a burglary in the year ending March 2025, according to the Office for National Statistics. And nationwide official data showed a 1.7% rise in reported burglaries that July.
It's a clear sign that protecting your home with a reliable home alarm system is as important as ever. And with so many types of alarms on the market, choosing the right home alarm system really matters. Because it's not just about preventing break-ins - it's about protecting the people, memories, and valuables that matter the most to you.
Why choosing the right home alarm matters
With so many different types of home alarms, it's easy to feel overwhelmed when choosing a home security system. Wired or wireless? Monitored or self-monitored? Smart or traditional? Each option has its own advantages, but not every alarm suits every type of property or lifestyle.
A reliable alarm system provides three key benefits: protection, peace of mind, and long-term value. Whether you live in a city apartment, a terraced house, or a detached home, the right solution will deter intruders, alert you and emergency services in seconds, and fit seamlessly into your daily routine.
This article will explore how to choose the best alarm system for your needs, and why professionally monitored alarm systems, like those from Verisure, offer an extra layer of security you can truly depend on.
The different types of home alarm systems
Understanding the main types of alarm systems is the first step in making an informed decision on the right home security system for your needs. Below are the most common options found in UK homes today.
Wired systems connect sensors and control panels through cables hidden within your walls. They are reliable and stable, ideal for homeowners looking for a long-term installation.
However, they usually require professional installation and can be more disruptive to fit, especially in existing homes where cabling needs to be concealed. Wired systems are best suited to larger or newly built properties where reliability and permanence are priorities.
Wireless alarms use radio or Wi-Fi connections between sensors, cameras, and control units. They're quick to install, easy to expand, and ideal for renters - or anyone who prefers a less invasive setup.
You might be wondering, are wireless alarms as reliable as wired ones? Modern wireless systems are secure and dependable. They are normally as reliable as wired ones, but their performance can depend on battery life and signal range. For small to medium-sized homes, they strike a great balance between convenience and flexibility.
Self-monitored alarm (sometimes called unmonitored) systems are often DIY systems that notify you directly, usually via a smartphone app, if motion or entry is detected. You'll receive an alert or siren, but must verify the situation and contact emergency services yourself if needed.
They can be appealing for their lower ongoing costs, but they rely entirely on your availability and phone connectivity. If you're asleep, at work, or travelling abroad, your alarm may trigger without any available response.
These systems can suit smaller homes or tech-savvy users who prefer to manage their own security, but they don't offer guaranteed protection when you can't respond.
Monitored alarms
Monitored alarms connect your home directly to a dedicated security centre. If an alarm is triggered, trained specialists verify the incident in real time, and contact the police or emergency services on your behalf.
Unlike self-monitored systems, monitored alarms ensure that someone always responds, even if you miss a notification or your phone battery dies. This 24/7 oversight provides a much stronger deterrent against burglars, and peace of mind that your home is protected day and night.
For many UK homeowners, monitored systems, such as those offered by Verisure, represent the gold standard of home protection, combining professional response with smart technology and seamless installation.
Smart alarms
Smart home alarms integrate with your smartphone or smart hub. Through a dedicated app, you can arm or disarm remotely, view camera footage, and receive instant notifications if motion or entry is detected.
Many smart systems now include voice control and AI-powered sensors that distinguish between pets and humans, reducing false alarms.
| Alarm type | Best for | Main advantages | Key considerations |
|---|---|---|---|
| Wired | Properties being built, renovated or rewired, where cables can be run easily | Very reliable, no batteries | Requires professional installation |
| Wireless | Almost any home, whether owned or rented, old or new, large or small | Easy installation, flexible | Batteries need maintenance |
| Self-monitored | People who are happy to check and respond to every alert themselves | Lower cost, full app control | You must handle all alerts yourself |
| Professionally monitored | Anyone who wants alarms checked and acted on 24/7, even when they can't respond | 24/7 professional response | Monthly service cost |
| Smart | Households that want to control and check their alarm from their phone | Remote control, integration | Needs Wi-Fi & app setup |
Core features to look for in a home alarm system
When comparing systems, it's important to look beyond brand names - and focus on the features that make a real difference. When choosing the right house alarm you should think about the following things:
- Motion and contact sensors for doors, windows, and main entry points.
- The control panel or hub, allows for easy arming and disarming.
- Cameras or video verification to confirm alerts and prevent false alarms.
- Mobile connectivity through a secure app.
- Backup power and GSM connectivity for reliability during outages.
- Tamper protection to detect interference or attempts to disable the system.
A strong alarm system should be integrated and adaptable, able to grow with your needs. For instance, Verisure's home security systems allow you to add detectors or smart cameras later on, without replacing your existing equipment. Check out some of the most frequently asked questions to help you plan what you might need.
Professional monitoring vs. self-monitoring
Many homeowners wonder: "Do I really need professional monitoring?"
As discussed in the section above, a self-monitored alarm sends alerts to your phone. This is fine if you're available 24/7, but it relies on you being connected and able to respond quickly - which isn't always realistic during holidays, work hours, or at night.
By contrast, a professionally monitored alarm means experts are watching over your home around the clock. If your alarm triggers, they verify the alert in real time and contact emergency services immediately if a threat is confirmed.
This fast, verified response not only ensures help arrives quickly, but also acts as a powerful deterrent; burglars know that monitored systems lead to faster police involvement.
In short:
- Self-monitored = cheaper upfront, but you're responsible for every alert.
- Professionally monitored = higher protection, continuous peace of mind.
Installation and maintenance considerations
When choosing a home security system, it's important to think about how your alarm is going to be installed and maintained. This can make a big difference to its effectiveness and long-term reliability.
DIY vs. professional installation
While many wireless alarms are marketed as "DIY-friendly," correct placement of sensors, sirens, and control units requires precision.
A sensor placed just a few centimetres off-angle can miss vital movement or trigger false alarms. Professional installers, such as Verisure's trained alarm installation technicians, ensure every device is positioned for maximum coverage, and test it thoroughly before activation.
Professional installation also includes:
- Configuration and demonstration of how your system works.
- Full connection to the monitoring centre.
- We offer support if you move home or make property changes later on.
DIY alarm vs. professionally monitored alarm
When choosing a home security system, one of the main differences to consider is how the system is paid for and how it is managed. You can choose a DIY alarm that you purchase with a single upfront payment, or a professionally installed and monitored alarm that comes with an ongoing monthly cost.
DIY alarms: a single upfront payment
DIY alarm systems are typically purchased upfront, with the equipment becoming yours once you've paid for it. They can be a straightforward option if you want to install and manage your own home security system.
With a DIY system, you'll generally be responsible for installing and configuring the equipment, positioning sensors and managing ongoing maintenance such as battery replacement. Depending on the system, additional features or services may also be available at an extra cost.
DIY alarms typically mean:
- A single upfront payment for the alarm equipment.
- Self-installation and responsibility for positioning and configuring the system.
- Ongoing maintenance managed by you, including tasks such as battery replacement.
Professionally monitored alarms typically mean:
- An ongoing monthly cost for the security service.
- Professional installation with the system configured and tested for your property.
- 24/7 professional monitoring as part of the ongoing service.
- Ongoing support for your security system, according to the terms of your service.
Verisure uses the professionally installed and monitored model, combining security equipment, professional installation and 24/7 monitoring as part of an ongoing service.
The right option depends on what you want from your home security system. A DIY alarm can provide a simple solution with a single upfront equipment cost, while a professionally installed and monitored alarm comes with an ongoing monthly cost for services such as professional installation, monitoring and ongoing support.
How do I choose the right home security system?
With so many options to choose from, even something relatively straightforward can become quite confusing. For example, if you're wondering what is the best alarm system for a house, it might differ from what works best for a flat. So, how do you choose the right home security system to fit your needs? Let's start with a simple checklist:
| Consideration | What to think about |
|---|---|
| Property size & layout | Larger homes may need multi-zone systems with extra sensors. |
| Level of risk | Urban areas or detached properties may benefit more from monitored systems. |
| Budget | Consider whether you prefer a single upfront equipment cost or an ongoing monthly cost for services such as professional monitoring and support. |
| Lifestyle | Smart systems suit people often away from home or with variable schedules. |
| Support model | Decide whether you want to install and manage your own system or have professional installation, monitoring and ongoing support. |
Taking these factors into account ensures you select a system that truly suits your home, not just one that's popular or inexpensive.
Why making the right choice matters
Choosing the right home security system is about more than comparing products; it's about finding the right balance of technology, reliability, and peace of mind.
Once you've considered your property type, lifestyle, and level of risk, the next step is choosing a system you can depend on day after day. A great home alarm should work quietly in the background, protecting your home and family without disruption or constant upkeep.
The best alarm system isn't necessarily the most expensive; it's the one that gives you confidence - fitting seamlessly into how you live. By understanding the main alarm types and what matters most to you, you can make an informed choice that keeps your home safe for years to come.

FAQs
The best home alarm system for your house will depend on your property type (e.g. size and layout), your lifestyle and habits, and the level of protection you need.
For most UK households, a professionally monitored alarm like Verisure offers the strongest security, providing 24/7 expert response and real-time verification if an alarm is triggered.
A monitored alarm connects your home to a professional security centre, where trained specialists verify alerts and contact emergency services if needed. An unmonitored alarm, on the other hand, sends alerts directly to your phone, leaving you responsible for checking the situation and calling for help.
It's simple: monitored features external verification; unmonitored, you're on your own.
Typically, the cost of a home security system varies depending on the following factors:
- Whether you rent or buy your home alarm
- The size of your home
- The number of add-ons you have (e.g. additional sensors or cameras).
You can buy DIY security systems outright with an upfront payment. Or, you can opt for professionally monitored alarm systems, which usually have a simple monthly fee that covers your equipment, installation, and 24/7 monitoring service. This means there are no large upfront costs or surprise maintenance fees, just ongoing, expert protection and support.
The best outdoor security systems combine reliable detection with professional monitoring. Look for systems with weather-resistant cameras, motion sensors, and real-time video verification to confirm alerts.
A professionally monitored system, such as Verisure's, offers an extra layer of protection by ensuring any detected activity is immediately verified and responded to. This helps to deter intruders before they even get close to your home.
Both wired and wireless cameras have their benefits for home protection:
- Wired systems are highly reliable, and ideal for larger or newly built properties where permanent installation is practical.
- Wireless systems, however, are easier to install and expand, making them perfect for renters or smaller homes.
Modern wireless cameras, in particular, are useful for offering flexibility without sacrificing quality (especially when supported by professional monitoring and regular maintenance).
The Verisure video doorbell has a motion detection range of approximately 5 to 7 metres from the camera, with a 110° horizontal field of view.
In practical terms this covers the entire area in front of your door, including:
- Anyone approaching your door from the front or at an angle
- Packages left on the doorstep
- Movement on your driveway or front path (if within 5 to 7m)
Night vision range: The infrared night vision LEDs provide clear footage from ~7 to 10 metres away in low-light conditions.
Professional protection you can depend on
When it comes to home security, real peace of mind comes from knowing that someone is always looking out for you. That's what professional monitoring provides: protection that never sleeps, and support you can trust whenever the unexpected happens.
Verisure's smart home alarm systems combine 24/7 monitoring, 360 detection technology, and expert response to help keep your home and family safe. Every system is professionally installed and tailored to your property, ensuring reliable coverage and fast communication with emergency services whenever needed.
