What Should You Look for in an Alarm System?

The main things to look for in an alarm system are the right security grade for your property, the option to have it monitored, proper encryption and supervision if it is wireless, tamper detection, app control, and an installer who surveys the property and stands behind the work. Get those right and the brand on the box barely matters. So the short answer is that the important choices are about grade, response and who fits it, far more than the badge or the number of sensors in the kit.

The reason it pays to know what to look for is that alarms are often sold on price and sensor count, which are the two things that matter least. At Bespoke AVS we fit and service alarm systems across Kent, the South East and London, and we spend a lot of time explaining what actually makes a difference before someone spends their money. This guide walks through each thing worth checking, and the warning signs that tell you to look elsewhere.

The right grade for the property

Alarms are built to recognised security grades, and the grade is the single most useful thing to get right, because it is what an insurer checks and what matches the system to the risk. Most homes are a Grade 2, while higher-value homes and commercial premises step up to a Grade 3. You can read the standards side on British Standards, but the practical thing to do is simply ask what grade is being fitted and why it suits your property. An installer who cannot answer that is not the one to use.

Whether it can be monitored

The next question is what happens when the alarm goes off. A bells-only system sounds a siren and hopes a neighbour acts. A monitored system sends the signal to a manned centre that can call a keyholder or request police, and a self-monitored one alerts your phone. You do not have to take monitoring, but you should look for a system that can be monitored later without being ripped out, so the option stays open as your needs change.

Encryption and supervision on wireless

If the system is wireless, and most now are, two features separate a serious one from a cheap kit. Encryption, usually rolling-code, stops a signal being captured and replayed. Supervision means the panel expects a regular check-in from every sensor and treats silence as a fault rather than a blind spot. Both should be standard, not upgrades, and if you are weighing up a connected system it is worth understanding wireless intruder alarms in a bit more depth.

Tamper detection and app control

Tamper detection means the system reacts if someone opens or moves a sensor, panel or sounder, which closes an obvious gap. App control is the modern convenience worth having, letting you arm and disarm, check the status and get alerts wherever you are. Neither is exotic any more, so look for both as part of the system rather than paid extras. And if you share the house with a cat or dog, look for pet-friendly sensors so the alarm ignores the pet but still catches a person.

The installer, not just the kit

This is the part most people underweight. In our experience, choosing on the installer works better than choosing on the kit because the same alarm fitted well and serviced for years beats a better alarm fitted badly and forgotten. Look for a proper survey rather than a price over the phone, insurance work undertaken, and someone who answers when the system faults. We are Kent County Council Trading Standards Checked, and we fit alarm systems to a survey rather than a fixed package. For the wider picture of what actually deters a break-in, the police-backed Secured by Design scheme is a good reference.

Bringing it together

What to look for in an alarm system comes down to a handful of things that rarely appear in the sales pitch, the right grade, the option to monitor it, encryption and supervision on wireless, tamper detection and app control, and above all an installer who surveys the property and stands behind the work. If you would like to see how those come together, the best alarm system for a home is a good next read. Get the checklist right and you end up with a system that protects the property for years rather than one that looked cheap on the day.
