Home Alarm: How to Truly Protect Your Home
A burglary never gives warning. We all know this in theory, but we usually only think about it after the fact – a forced window at the neighbor's, an article in the local press, or worse, an unpleasant surprise upon returning from vacation. That's why more and more people are taking the plunge before something happens, rather than after.
We regularly receive similar questions at SecuriShop: which alarm to choose, how much does it really cost, do you need a subscription, is it complicated to install yourself? This guide summarizes the most common answers we provide to help you see more clearly before buying.
Why an Alarm Truly Makes a Difference
The first thing often overlooked is that an alarm is not just a tool to react during a burglary; it's primarily a tool to prevent it. Most burglars are not professionals who study a house for weeks. In the vast majority of cases, they are opportunists who move on as soon as they spot a siren, a sticker, or a clearly visible camera on the facade. The simple act of showing that the dwelling is protected already does a good part of the job.
There's also everything you don't see at first glance: being able to check from your phone that everything is fine while on vacation, receiving a notification if someone forces a door while you're sleeping, or simply sleeping soundly on the weekend. And the icing on the cake, several insurers offer a discount on home insurance premiums when the dwelling is equipped with a certified system, especially if it's connected to an approved remote monitoring service. It's worth checking directly with your insurer, as conditions vary quite a bit from one company to another.
The Main Categories of Alarm Systems
Before comparing specific models, you first need to know which category to look into. There are generally four approaches, and honestly, no single one is always better than the others – it all depends on your home.
Wired Alarm
This is the long-term safe bet: no batteries to change, no risk of radio jamming. On the other hand, installation requires running cables through walls, which primarily reserves it for new constructions or major renovations where walls are already open.
Wireless Alarm
This is currently the most chosen option for an existing dwelling, simply because nothing needs to be touched: detectors communicate with the central unit via radio waves. Serious models use strong encryption and anti-jamming protection to prevent a slightly equipped burglar from cutting the signal before acting. The only maintenance required is replacing batteries from time to time.
GSM and Connected Alarm
These systems send alerts directly to your phone via the mobile network, meaning they continue to function even if someone cuts your internet box before entering. This has become almost a standard today, and we clearly recommend a central unit with dual connectivity (IP and 4G) for this specific reason.
Hybrid Alarm
A mix of the first two approaches: wiring in technical areas like the garage or cellar, wireless detectors in living rooms. This is often what installers suggest when a house is a bit older and you want the best of both worlds without redoing everything.
What Really Makes a Difference When Choosing
Once you have an idea of the system type, several technical details deserve to be checked before buying, because this is often where the difference lies between a reliable system and one that disappoints after six months.
The EN 50131 standard classifies professional systems into four grades. For a typical private home, grade 2 is largely sufficient; grade 3 is more justified for a property with a higher risk. The backup battery is another point not to be neglected: in case of a power outage, the central unit must continue to function for several hours, not just a few minutes. Also, verify that the mobile application truly allows you to arm, disarm, and view the history in real-time – some entry-level applications are more limited than they appear on the product sheet. Finally, if you plan to add cameras one day, it's worth checking now that the system can connect to them, rather than having to change everything later.
With or Without Remote Monitoring?
An alarm can function perfectly well on its own: it alerts you and your loved ones, and that's it. It can also be connected to a remote monitoring center that takes over 24/7 and can, depending on the contract, send someone to the site.
One point to be aware of if you opt for the latter: in Belgium, any installation connected to remote monitoring, or exceeding certain thresholds, must comply with the accreditation requirements of the FPS Home Affairs. If you go through a serious professional installer, they usually handle this for you, but it's worth asking before signing. For most households, a connected alarm with smartphone notification, without mandatory subscription, already covers the need very well.
How Much Does It Actually Cost?
This is often the first question we are asked, and the honest answer is: it depends enormously on the level of equipment. To give you an idea:
Expect to pay from around €70 for an entry-level kit with a central unit and one or two detectors. Between €150 and €500, you enter the mid-range, with a complete system covering a standard house: several detectors, a siren, a decent mobile application. Above €1000, we are talking about a professional installation with integrated remote monitoring and video surveillance, usually grade 3.
A small piece of advice we often give to Walloon customers: some municipalities offer local grants that can cover 10 to 30% of the cost of installing an anti-burglary system. It's really worth checking with your municipality before buying, rather than after.
The Most Common Mistakes We See
Even the best system in the world loses much of its value if it is poorly installed or misused daily. The most frequent pitfalls we observe with our customers: focusing only on the front door while forgetting the garage, the bathroom window, or the skylight; placing a motion detector directly opposite a radiator or a south-facing bay window, which increases false alarms; never testing the alarm after a battery change; forgetting to explain how the system works to other family members, which always ends up triggering a false alarm at the worst possible moment; and installing the control panel in plain sight right next to the door, which makes it far too easy to neutralize in case of a quick intrusion.
Our Most Frequently Asked Questions
Is a wireless alarm really reliable?
Yes, provided you opt for a professional system with encryption and anti-jamming. For most already built houses, this is also the option we recommend first, simply because it avoids construction work.
Is a subscription absolutely necessary?
No. Most consumer-connected alarms work very well without a subscription: alerts arrive directly on your phone. A subscription only makes sense if you want true remote monitoring with possible on-site intervention.
Does it lower my insurance premium?
It depends on the insurers. The only way to know for sure is to ask them directly, specifying whether your system is connected to an approved remote monitoring service or not.
How long does installation take?
For a typical residential wireless system, allow one to three hours, with no major drilling work.
Where should the alarm control panel be placed?
In a discreet location, out of sight from the outside, and especially not right next to the front door – that's the first place a burglar will look in case of a quick intrusion.
In Conclusion
Securing your home no longer requires a huge budget or endless work. Current wireless systems can be installed in a few hours and are entirely controlled from a phone. The real task is primarily taking the time to choose a system adapted to the size of your home and the level of peace of mind you seek – not necessarily the most expensive, but the right one for your situation.
