An alarm system that tells you straight away.
Ajax, installed and tested: a phone alert within a second, a siren, night mode, no subscription. It keeps working when the power or the internet goes down. The equipment is yours — add a patrol from a security company if you want one, and switch companies without changing the alarm.

The house at nightthree modes — tap one
Away: all 11 detectors are armed — doors, windows, glass-break and motion in the rooms; the sirens are ready. If a door opens, the siren and the alert follow within a second.

02What happens
From an open door to your phone — in a second.
Five steps the system takes on its own. And the four things customers ask before they're convinced.
0 s1The detectora door opens, glass breaks or someone walks through a room
0.15 s2The hubgets the signal over the radio and checks the mode: Away, Night, Home
within a second3Siren and phonethe sirens go off and the alert reaches every phone in the family
you4You decidethe MotionCam photo, the camera, a neighbour, the police — all from your phone
under contract5The patrolif you have a contract with a security company, the signal goes to them too
If the power goes offthe hub runs on its battery for up to 16 hours and alerts you when the power goes off and when it comes back. The detectors have their own batteries.
If the internet goes downtwo SIM cards in the hub — alerts go over the mobile network. For a holiday home without internet, there's a 4G hub.
Batteries4–7 years depending on the detector; the app warns you a month ahead, and a swap takes two minutes.
Jammingthe hub monitors the radio link and alerts you if it's jammed; the connection is encrypted, with backup frequencies.
Night mode and the dog. You sleep with the alarm set: doors, windows and glass are armed, the indoor motion detectors are off. The detectors ignore a dog or cat up to 20 kg and 50 cm tall — we set them up for your pet during installation.
03Who responds
On your own, by phone or with a patrol. You choose, and the equipment stays yours.
We install, set up and test. We're not a security company — the patrol comes from a licensed company of your choice that the system connects to.
on your ownno feeThe siren and the alert on your phone. You check the camera or the photo, then call a neighbour or 112. For a flat in an apartment block, that's usually enough — a siren at 3 in the morning wakes the whole building.
phone monitoring€9–€16/monthA monitoring centre watches the signals and calls you if the alarm goes off; no patrol. For a holiday home, or when you don't want to be the only one watching your phone.
patrol€15–€25/monthA licensed security company sends a patrol when an alarm comes in. For a home €15–€25, for a shop or office €20–€40 a month. You can change company without changing the alarm — the equipment is yours, not theirs.
Monthly fees are those published by BODU SOD and sodsecurity.com, checked on 22.09.2026 — a guide, not our quote. Only the patrol company needs a licence — not you, and not us.

A flat — from €742: hub, door sensor, sensors for two rooms, siren, keypad, key fob, installation and testing. A house from €1,124, a shop from €979, a holiday home with 4G from €1,076. Every device is a line item with its own price — build yours in the calculator.
No. The Ajax app is free, and so are the notifications. The only running cost after installation is the SIM card in the hub, if you want a backup connection that works without internet — €2–€3 a month with your mobile provider. You only get a patrol response if you sign a contract with a security company.
The hub runs on its own battery for up to 16 hours and takes two SIM cards — if the power or internet drops, you still get the alert, including one about the outage itself. The detectors run on batteries for 4–7 years; the app tells you a month in advance when they need changing.
Not if night mode is on: the doors, windows and glass stay protected, while the motion detectors inside are switched off. You get up for a glass of water, your child walks down the hallway — silence. But if a window opens, the siren goes off.
The motion detectors have pet immunity up to 20 kg and 50 cm in height — a dog or cat on the floor doesn't count. For a bigger dog we position them to cover the perimeter rather than the floor, or rely on the door and window sensors.
The hub monitors the radio channel and sends an alert if someone tries to jam it; the link to the detectors is encrypted, with two backup frequencies. Access is through your own account and password; we don't keep access after handover.
Not necessarily. Self-monitored: the siren and an alert on your phone, with no monthly fee. If you want a patrol response — a licensed security company of your choice, €15–€25 a month for a home; we set the system up to connect to them. The equipment stays yours, and you can change company without changing the alarm.
Yes. The old wired detectors can be connected to Ajax with a module, but it's usually cheaper and neater to replace them with wireless ones. Your patrol contract with the security company can carry on with the new system.
The MotionCam detector sends a photo when the alarm is triggered — you can see whether it's a burglar or the cat before you ring anyone. CCTV cameras complement the alarm; they have their own separate page.
A flat takes half a day, a house a day. No cables and no chasing: the detectors are wireless and battery-powered, and they're stuck on or screwed in place. The hub needs a socket and, if you have one, a router.
24 months on the installation; devices are covered by the manufacturer's warranty. Payment after installation and testing — always with a contract and an invoice.
