The need for home security is growing. Burglaries, break-ins and vandalism unfortunately still occur regularly. Yet many people do not want to take out an expensive security subscription. Logical, because a fixed monthly amount is not attractive or necessary for everyone. Fortunately, there is a smart solution: itAjax alarm system. In this blog you will discover how to keep your home safewithout subscription costs, with the reliability of a professional system.
Previously it was standard: anyone who wanted an alarm system had to have onesign a contract with a security company. Often with a control room, fixed monthly costs and a long term. But times have changed.
💸Cost savings:you don't want to spend €15–30 per month
📱Keep control via your smartphone
🔧More freedom:install yourself, manage yourself
🔒No dependence on an external party
With itAjax alarm systemyou can secure your home professionally, without mandatory monthly costs. And while you do enjoy smart notifications, camera integration and remote control.
The Ajax system is completely modular and wireless. You choose which parts you want to use: such as acentral hub, motion detectors, window sensorsandsiren(s). Everything works via its own secure connection (Jeweler protocol) and is connected to your smartphone via the freeAjax app.
No subscription required:you buy the system once
Push notifications and notifications via text message/call are free(with SIM card)
Works with WiFi, LAN and/or 4G connection
Backup battery ensures operation in the event of a power outage
Tip:If you later want to connect to a control room, you can still do so. But that is optional, not mandatory.
You can easily start with a basic module and expand whenever you want. A popular combination is:
Ajax Hub 2 (4G)– the central unit with LAN, WiFi and SIM card
Ajax DoorProtect– sensor on the front door
Ajax MotionProtect– motion detector in the hall or living room
Ajax HomeSiren– indoor siren or 105 dB
Ajax SpaceControl– remote control to activate/deactivate the system
One-off costs:from approx. €400–600, depending on the composition.
No monthly obligations, but you will always receive an immediate notification on your phone in case of suspicious movement or open window/door. And the sirens? It makes itself heard loud and clear.
You only pay for the hardware, and then you have full control. Ideal for starters, homeowners or people who want cost-conscious security.
Ajax is designed according to European security standards and is also used by security companies – but you don't need an intermediary.
If movement is detected or a window opens, you (and possibly other family members) will immediately receive a push notification, text message or call.
You can set the siren to go off when there is movement, lights to turn on when an alarm occurs, or the camera to take a snapshot. Everything via the Ajax app.
The hub automatically switches to 4G and battery, so your security continues to work – even if the internet or power goes out.
No, it's a control roomnot mandatory. Ajax also works completely independently. If you want extra security, you can optionally connect a control room via an Ajax partner.
Yes. The security comes from the system itself: encrypted connections, reliable hardware, smart notifications. The only difference is that you are the first to receive a notification, instead of a central operator.
At least an Ajax Hub, one motion detector and a door/window sensor. Possibly a siren or remote control. The Ajax Hub 2 (4G) is perfect for those who want to work without a subscription, thanks to the SIM card option.
This type of security is ideal for:
Private individuals who want to protect their home, shed or garage
Tenants who want to take the system with them when they move
Small entrepreneurs or self-employed people who want to secure their office or work
Parents who want to use the app to check whether their children arrive home safely
You are not bound by contracts or obligations – and that gives you peace of mind.
TheAjax Hub 2 (4G)is the ideal basis if you don't want any monthly costs. You insert a SIM card (prepaid or subscription of your choice), connect it to your WiFi or LAN, and you're done.

This is the heart of your system – and you don't need anyone else to be safe.
With an Ajax alarm system you chooseprofessional security on your own terms. No expensive service contracts. No obligations. No hidden costs. Only you decide what you need and when.
