How to Choose the Right Burglar Alarm System for Your Home

Electric Water Heaters: Everything You Need to Know

The Complete Guide to Door Entry Systems

Beginner's Guide to Building a Smart Home on a Budget

Choosing a burglar alarm system can feel overwhelming. Walk into any conversation about home security and someone will mention wired versus wireless, zones, PIR sensors, monitored versus unmonitored — and before long it all blurs together. The good news is that once you understand the basics, the right system becomes much clearer. 

This guide will walk you through everything you need to know, from how modern alarm systems actually work to which brands are worth your money — including those you can order right now from Alert Electrical.

What Does a Modern Burglar Alarm System Actually Include?

A burglar alarm system is more than just a siren on the side of your house. A complete system typically consists of several key components working together:

 is the brain of the operation. It receives signals from every sensor in your property, decides whether to trigger an alert, and manages how users arm and disarm the system.

 are placed around your home at entry points and in key internal spaces. These include door and window contacts (which detect if they're opened), passive infrared (PIR) motion detectors (which sense body heat and movement), and sometimes vibration or shock sensors for added coverage.

 is where you interact with the system day to day — entering your PIN to arm or disarm, checking the status of zones, and accessing settings.

 is your visible deterrent. A good external bell box on a front elevation does more to deter opportunists than almost anything else. Most modern ones include a tamper-proof strobe light too.

 is what separates a basic bells-only alarm from a smarter setup. This component connects your system to your smartphone, a monitoring centre, or both — sending alerts the moment something triggers.

Understanding these components makes it easier to compare systems and spot what's included in any kit you're considering.

Wired vs. Wireless: Which Is Better for Your Home?

This is the question most homeowners ask first, and the honest answer is: it depends on your property and circumstances.

 have been the industry standard for decades, and for good reason. Once installed, they're extremely reliable. There are no batteries to replace in sensors, no radio frequency interference to worry about, and the connection between components is hardwired — which is inherently more difficult to disrupt or jam. The trade-off is installation. Running cables through walls, floors, and ceilings takes time and requires either a confident DIY approach or a professional installer.

 have improved enormously over recent years. Modern wireless systems use encrypted radio signals between sensors and the control panel, making them far more secure than older generations. They're quicker to install, less disruptive to your home, and easier to expand. They're also an excellent choice if you're renting or don't want to chase cables into plasterwork. The ongoing consideration is battery maintenance — you'll need to replace or recharge sensor batteries periodically, typically every few years depending on the system.

For newer builds, renovations, or situations where installation disruption needs to be minimal, wireless often wins. For larger properties or commercial sites where long-term reliability and low maintenance are priorities, wired systems remain a strong choice. Many installers now favour 

 that combine a wired control panel with wireless peripheral devices — giving you the best of both worlds.

Burglar Alarm Brands Available at Alert Electrical

At Alert Electrical, we stock a carefully selected range of alarm brands trusted by professional installers across the UK. Here's a closer look at the key names you'll find on our 

Texecom is one of the most respected names in the UK alarm industry. Their main ranges — 

 — cover the full spectrum from smaller residential properties to large commercial installations.

 is designed with homeowners and smaller installations in mind, prioritising ease of use, straightforward installation, and reliable day-to-day performance. The R8 Plus model includes a communicator interface, making it compatible with external signalling equipment for monitored setups. It's worth noting that some Veritas panels are certified to Grade 1, rather than Grade 2 — so if you require a Grade 2 system for insurance or police response purposes, confirm the specification of the specific panel before you buy.

 is where Texecom excels for more demanding installations. These panels are available in wired, wireless, and hybrid configurations, and are independently certified to Grade 2 and Grade 3 standards — suitable for both residential and high-risk commercial use. The system supports encrypted sensor transmission, an integral proximity fob reader, and up to four partitions, meaning you can run separate alarm zones for different areas of a property from a single control panel. Smartphone app control and remote servicing are available via the optional SmartCom communicator module, which connects the panel to Texecom Cloud. Basic app connectivity through Texecom Connect is free; a small annual fee applies if you want full remote programming access.

Pyronix is another industry favourite, well known for the 

 range — currently on V11. The Enforcer V11 panel features 34 onboard zones (32 wireless and 2 wired), which can be expanded to a total of 66 zones by adding optional wired expansion modules, with support for up to 80 users. Wi-Fi is built into the main PCB as standard, enabling smartphone app access via the HomeControl2.0 app with push notifications, without needing an extra module.

Sensor data is encrypted, and the system supports multiple partitions for multi-area properties. Because Pyronix is part of the Hikvision group, there is a natural integration path with Hikvision CCTV equipment — a real bonus if you're building a broader security system. Note that PyronixCloud connectivity is free for the first 12 months; a subscription fee applies thereafter, payable via your installer.

Pyronix products are designed to be installed by trained professionals. If you're working with a qualified alarm engineer, they'll likely know the Enforcer range well and be comfortable programming it to suit your exact requirements.

Scantronic has been a trusted name in the security industry for over 30 years. Now part of Eaton, they produce the 

 range of alarm systems for both residential and commercial applications.

The i-On Compact is a particularly popular choice. It's a wireless panel that uses the SecureConnect app for remote monitoring, arming, and disarming from anywhere in the world. It supports Amazon Alexa voice control and integrates with the Control4 home automation platform — making it a strong choice if you want your alarm to fit neatly into an existing smart home setup. Communication options include built-in Ethernet plus optional GSM, and the system supports connection to a professional alarm receiving centre for full monitoring.

Scantronic systems are known for their reliability and are widely used in offices, government buildings, and retail environments as well as homes — testament to their engineering pedigree and track record in the field.

One of the most common mistakes when choosing an alarm system is underestimating how many zones you'll need. A zone is simply a section of your alarm system — typically one sensor or a group of sensors on a single circuit.

two to three bedroom terraced or semi-detached house

 will typically need between 6 and 10 zones: front and back door contacts, two or three internal PIRs, and perhaps a garage or outbuilding.

 might need 10 to 16 zones once you add utility rooms, a driveway, and multiple floors.

 or buildings with several distinct areas will often require 20+ zones, and potentially a partitioned system to allow different areas to be armed independently.

Always buy a panel with room to grow. Adding zones to a system that's already at capacity usually means replacing the panel entirely, which is far more disruptive and expensive than choosing a slightly larger panel at the outset.

Your 5 Most Frequently Asked Questions About Home Burglar Alarms — Answered

1. Do I need a professional to install a burglar alarm, or can I do it myself?

Both options are available — and the right choice largely depends on the system you're buying and your own confidence level.

Many wireless alarm systems are now designed for DIY installation, with step-by-step setup guides and app-based configuration. If you're buying a straightforward kit for a standard home, this can be a perfectly sensible route.

However, for professional-grade systems like Texecom Premier Elite or Pyronix Enforcer, installation and programming is genuinely complex. These systems are designed to be configured by trained engineers, and getting them wrong can mean false alarms, gaps in coverage, or a system that isn't NSI or SSAIB compliant — which matters if you're connecting to a monitoring centre or need the installation to meet your insurer's requirements. For anything beyond a basic DIY kit, we'd recommend using an accredited installer.

2. What's the difference between a monitored and an unmonitored alarm?

 (also called a bells-only alarm) triggers a siren and, on smarter systems, sends a push notification to your phone when activated. It's your responsibility — or a neighbour's — to notice and respond.

 connects your system to a professional alarm receiving centre (ARC), which is staffed around the clock. When your alarm triggers, the ARC contacts you first to check whether it's genuine, and can then alert the police or a nominated keyholder on your behalf. Monitoring is typically available through a monthly or annual subscription and provides a much faster, more reliable response — particularly useful if you travel frequently or your property is in a quieter location.

To qualify for police response in the UK, your alarm system generally needs to meet Grade 2 or above under BS EN 50131 and be installed and maintained to the relevant British Standard. Your installer can advise whether a particular system and setup meets these requirements.

3. Will a burglar alarm lower my home insurance premium?

In most cases, yes — though the exact saving varies between insurers and policy types. A visible, working alarm system tells insurers that you've taken active steps to secure your property, which reduces their risk and can translate into a meaningful discount on your premium.

The best results tend to come from systems that are professionally installed, maintained, and ideally NSI or SSAIB approved. Some insurers specifically require a certain grade of alarm for certain levels of cover. It's always worth calling your insurer before you buy to ask what they recognise — you might find that a modest investment in a quality alarm system pays for itself in insurance savings over just a year or two.

4. How do I stop my burglar alarm from going off by mistake?

False alarms are usually caused by one of a handful of issues: failing sensor batteries, poorly positioned PIR detectors, pets triggering motion sensors, or draughts and moving objects (like curtains or balloons) in the sensor's field of view.

 — avoid pointing them at windows, radiators, or vents where heat fluctuations can cause false triggers.

 if you have cats or dogs. These are designed to ignore animals below a certain weight threshold.

 — most systems will give you a low battery warning, but it's worth checking sensors annually even without one.

 — an annual check by a qualified engineer can catch early problems before they cause issues.

If false alarms persist, your installer can usually adjust the sensitivity settings on individual sensors or recommend a different detector type for a particular location.

5. Can I add smart home integration to my burglar alarm?

Yes — and it's becoming increasingly common. Several systems available at Alert Electrical offer integration with smart home platforms. Scantronic's i-On range supports Amazon Alexa voice control and integrates with the Control4 home automation platform. Pyronix systems connect with Hikvision's wider ecosystem, which includes CCTV cameras and smart automation features.

Even if your chosen panel doesn't offer native smart home integration, many can be connected to third-party home automation hubs via add-on modules. This opens up possibilities like automatically arming your alarm when you lock your smart door, or receiving a notification on your phone whenever a sensor is triggered.

If smart home integration is a priority, it's worth clarifying exactly what's possible before you buy — some integrations require specific communicator modules that aren't included in standard kits.
