Short answer
Ajax alarm system is a wireless security system where the hub acts as the center of the system. Various devices are connected to the hub, which together protect the property and send alarms or notifications when something happens. The system is suitable for both homes and businesses and is appreciated for being easy to expand over time.
How does the Ajax alarm system work?
The foundation of an Ajax system is the hub. It acts as the brain of the system and keeps in touch with all connected devices. If a door is opened, movement is detected or another sensor reacts, the information is sent through the hub.
This allows you to build a system that suits your property. A smaller apartment may only need a hub, a magnetic contact and a motion detector, while a larger villa or business may need more sensors, sirens and several different protection zones.
What makes Ajax alarm systems interesting to many is that they don't have to be complicated from the start. You can start with a simpler solution and then expand the system as your needs change.

What does an Ajax alarm consist of?
An Ajax system can be put together in different ways depending on the property to be protected, but the system often consists of a few important parts.
Hub
The hub is the central unit that connects the system's various products. It is the one that receives signals and sends information if something happens.
Motion detectors
Motion detectors are used to detect movement in, for example, hallways, living rooms, offices, shops, warehouses or other important areas.
Magnetic contacts
Magnetic contacts are used on doors and windows to detect when something is opened, making them important for shell protection.
Sirens
Sirens are used to provide clear alarm indications and deter burglary attempts.
Other accessories
Depending on needs, the system can also be supplemented with, for example, fire detection, keypads, remote controls and other devices.
How long does the Ajax alarm range?
A very common question is how long the range of an Ajax alarm is. The short answer is that the range is often very good, up to 2000 meters, but the actual range is always affected by the environment where the system is installed.
In practice, there are several things that affect the signal, such as walls and floors, metal and other interfering materials, the building layout, and how the hub and sensors are placed. Whether the environment is open or more complex plays a big role in the result.
This means that no two installations will work exactly the same. In a smaller home, communication often works very smoothly, while larger houses, multiple floors or premises with more material between units may require better planning.
The most important thing is therefore not only to look at technical specifications, but also to think about what the property actually looks like. A good location of the hub and the correct placement of the sensors make a big difference to how well the system works in everyday life.
Ajax Hub 2 vs Hub 2 Plus
When you start comparing different solutions within Ajax, the question often arises about the difference between Ajax Hub 2 and Ajax Hub 2 Plus.
Both models act as the central unit of the system, but the Hub 2 Plus is a more advanced option. It is better suited for larger or more future-proof installations, while the Hub 2 is often a good choice for smaller or more basic systems.
Ajax Hub 2
Hub 2 is well suited for many common installations where you want a stable and modern alarm system without the system needing to be too large.
It is often well suited for:
- apartments
- smaller villas
- small offices
- smaller businesses
Ajax Hub 2 Plus
Hub 2 Plus is better suited when you want higher capacity, more options and more margin for future expansion.
It is often better suited for:
- larger villas
- stores
- larger office
- businesses with multiple users
- installations where you want to be able to expand the system further over time
What is the biggest difference?
The difference is primarily about capacity, connectivity options and how large a system the hub is intended to handle.
If you already know that you want to expand the system significantly, or want a more powerful solution from the start, the Hub 2 Plus is often the stronger choice. For simpler needs, the Hub 2 can go a long way.

How does Ajax MotionProtect work?
Ajax MotionProtect is a motion detector used to detect movement indoors. It is an important part of many Ajax installations and is often used in, for example, hallways, living rooms, entrances, offices and other areas where someone is likely to pass.
When the alarm system is activated and the sensor registers movement, the information is sent to the hub, which then handles the alarm or notification.
MotionProtect is often used in conjunction with other parts of the system, such as magnetic contacts on doors and windows, to provide both shell protection and motion protection.
Important things to consider when placing
For motion detection to work as well as possible, the sensor needs to be placed correctly from the start. It is good to consider that it should cover relevant areas, not have unnecessary obstacles in front of it and be located where a person is likely to pass. Height and direction also play a big role in how effective the detection will be in practice.
Correct placement is at least as important as the choice of sensor.
