How It Works – Secure Your Home in 5 Simple Steps

1. Build Your Alarm System

Choose your base and expand as you wish

Select an Ajax Hub (central unit) and easily add individual Ajax products, such as motion detectors, door and window sensors, or sirens.

We recommend the Hub 2 Plus. Thanks to the built-in Wi-Fi module, you can place the Hub flexibly anywhere, without being tied to an internet cable. This is especially useful because in some areas of the house, the mobile data network (for a SIM card) has better coverage than, for example, the utility closet.

Indoor Motion Detectors.
We provide the MotionCam exclusively in the PhOD version, allowing you to request a photo whenever you want.

Door & Window Sensors

Sirens
To scare off intruders quickly, noise is the only thing that truly works.
That’s why the powerful Ajax StreetSiren is an absolute must for every home!
Loud, clear, and essential for optimal security.

Control Devices
These control devices can be used locally, ideal for tenants, gardeners or other users. In addition, you can always use the Ajax app anywhere in the world, giving you full control of your security remotely.

Additional Security Products
Complete your Ajax system with smoke detectors, warning signs, and other accessories.

Outdoor sensors available exclusively with professional installation
We do not sell outdoor sensors online, as their installation requires specific knowledge and experience. In Spain, there are many street cats, which means outdoor sensors must be installed very carefully to prevent false alarms. Correct mounting height and positioning are crucial.

In addition, several Ajax outdoor sensors are not resistant to cats and other animals. We therefore consider these sensors unsuitable for reliable outdoor security.

If you require outdoor sensors, you can only choose our full professional installation service. During this service, we assess the situation on site and install the correct sensors in the proper positions.

SIM Card Backup: Essential for Reliable Security in Spain

In Spain, power outages are a common risk during break-ins: intruders can easily cut the power via the exposed utility box on the street. Without electricity, your router goes offline, Wi-Fi is lost, and the alarm system can no longer send notifications to your smartphone.

The Solution: SIM Card as a Backup Connection
With a SIM card, your system stays online even during power outages. It automatically switches to mobile internet (4G/5G) for instant notifications—crucial for peace of mind.

We sell special SIM cards for alarm systems that can roam worldwide and work with any network. When you order a SIM card with your alarm system, we install it in advance and program all the settings. As soon as you connect the Hub, the SIM card is online and serves as a stable backup connection. This ensures your alarm system remains fully operational, regardless of power or internet failures.

Don’t have fixed internet at your home?
Then order the SIM card “without fixed internet.”
The alarm system will then operate entirely via the pre-installed SIM card, ready to use immediately.
