The Home Alarm Hub
Everything you need to know about home alarms — planning, terminology, installation, and frequently asked questions. Built on Ajax, delivered by Alarmly.
Together with Ajax, we offer a truly unique alarm solution. Our packages give you both freedom and security — two feelings that are part of Alarmly's DNA. With Ajax you get a sleek alarm system for both home and business. Ajax is simple to manage, both for administering users and for configuring new functions.
Look at what you pay in the long run — an alarm is a long-term investment meant to help you for years. It can be tempting to jump at the first cheap offer, but that is not always what saves you money in the long run.
- •We make sure you get a durable solution that pays for itself over time.
- •It matters more to us that you get the alarm you actually need than that we sell you more than you need.
- •No commitment period on purchases — we want to earn your trust every month, not just at signing.
Alarm companies often present their own statistics on what home alarms help against, and to what extent. Those numbers do not always match what insurers or the police say.
We don't want to be a company that shapes a worldview to fit our product — we want our product to fit an actual reality. That means different things for different people in different parts of the country, which is why we let you tailor your own alarm package in our configurator.
A short guide to planning alarms for different environments.
Perimeter protection means opening detectors fitted to doors and windows — when the contact breaks, the alarm triggers. Combined with a classic motion detector, it lets you move freely around the house, so you can keep the alarm on while you sleep, cook, or are upstairs.
You often don't need to cover an entire home to get solid protection. The more motion detectors you add, the more expensive it gets. Does the base package cover the critical areas? Are there passages you must cross to move around? Where do you keep your valuables? A well-thought-out placement saves money while still doing its job.
It's generally easier to get in at ground level, but not always. Think like a burglar — are there ladders, bins, or garage roofs near windows that make upper floors easier to reach? Identify the vulnerable points and secure them with motion detectors.
Many people skip securing the garage simply because it doesn't feel like it holds anything of real value. But tools, bikes, and leisure equipment are attractive to thieves. For unheated garages, there are detectors rated for low temperatures.
A burglary almost always starts with the offender scoping out the house. An outdoor alarm makes it harder to plan a break-in undisturbed. A connected camera also makes it easier to protect bikes, boats, cars, and leisure equipment often kept in the garden, driveway, or yard.
There are pet-immune motion detectors for pets up to 20-25 kg, and heavier-duty garage/storage detectors that handle pets up to 60 kg — so you can keep the alarm active even with pets at home.
Terminology for some of the most common devices in a home alarm.
- Keypad
- Used to arm and disarm the system, and can also send a panic alarm in an emergency. Several keypads can be used in the same system, for example to control separate areas.
- Opening detector
- Fitted to doors and windows where you want perimeter protection — the alarm triggers when the contact breaks as the door or window opens.
- Motion detector
- Covers larger indoor areas. Available in a pet-friendly model for pets up to 20-25 kg, and a 360° ceiling-mounted variant similar to a smoke detector.
- Camera detector
- A motion detector with a built-in camera, for indoor or outdoor use. Sends photos to the app and monitoring station when the alarm triggers, if that service is selected.
- Glass break detector
- Gives an early warning when a window is broken. The acoustic version listens for the sound of breaking glass across a whole room; the vibration version mounts directly on the glass and senses the unique vibration of a break.
- Smoke detector
- Always active, whether the alarm is armed or not. Replaces a traditional smoke alarm, so you do not need both.
- Zone types
- A detector can be programmed with different behaviors: entry delay (a countdown before the alarm triggers, giving you time to disarm), instant (triggers immediately with no delay), and follower (allows passage after an entry-delay detector has already been triggered).
We often get asked "how hard is it to install a home alarm?" — the answer is that it is not particularly hard if you are handy and used to fixing things at home. If you are unsure, we recommend booking professional installation to be on the safe side.

Everyone has heard that you should put your lights on a timer when you're away — a classic that, in all honesty, only works so-so on its own. But combined with a home alarm, there are several things that can further deter burglary.
- •Perimeter protection: solid, modern windows and doors are perhaps your strongest weapon against intruders, and well worth the price.
- •The mail slot: a letterbox tool can be used to unlock a door from a mail slot. If your door has an inside handle-lock, consider blocking the slot or changing the door.
- •The mail: an overflowing mailbox signals you are away — ask a neighbor or friend to empty it regularly.
- •Vacation photos: hold off posting vacation photos publicly until you are home, or use locked accounts.
- •The car: a car in the driveway is good. A car that changes position every so often is better.
- •Remote control: smart plugs let you control things like the stereo remotely from your phone — the more randomly the home is used, the more convincing it looks.
- •A little lived-in mess: dishes on the counter or clothes on the floor create the impression someone was just there.
- •Visibility: a tall hedge gives you more privacy, but also a more sheltered workspace for an intruder. Increasing visibility where possible can help deter break-ins.
- •Motion-activated lighting: lights that suddenly switch on are both surprising and revealing — a simple measure that need not cost much.
- •The lawn and driveway: an unmown lawn or an unshoveled walkway speaks for itself.
- •The bin: an empty trash can at the wrong time is also a clear sign.
- •Laundry: laundry drying outside looks pleasant — and deterring to an intruder.
- •Good neighbors: let your neighbors know when you will be away for a while. Neighborhood watch is still one of the best ways to prevent burglary in your area.
