Ajax home security system

After twenty-five years covering technology, especially that focused on the Apple world, there are few things that make me raise an eyebrow with interest. But when they contacted me from Ajax to propose that I know better about their home security system, I must admit that I sat up in my chair, immediately interested in knowing more.

The contact resulted in a complete dispatch of the great diversity of devices Ajax has to control every aspect of home security, so much so that it is almost overwhelming.

Some of the different devices that make up the Ajax home security system

As you can see, Ajax has practically any need controlled, and if you don’t see it here, visit its product page because they surely have a device that does what you need.

Ajax’s home security system uses a system of unique QR codes engraved on each device (not to be confused with the QR code that is printed on each box, which, of course, is not used to add them to the hub).

Download the Ajax app

Once you have downloaded the app, in order to start adding devices, you will have to create an account and verify your phone number using the different codes that will be sent to you in an SMS and in an email (both) to the accounts you have provided.

The app is initially easy to use, by adding the systems that we want to control at the beginning. However, it could really debug the mechanism of how to add new devices to the Hub when it is not done the first time, because it took us a long time to touch up and down buttons until we found (understood) the system for the app to register a new sensor .

We would also like to add that it may be our limitation and that other users find it obvious, but -how it cannot be otherwise- we use our capacity as a viable measure of configuration simplicity.

The first thing is to register the hub that will control all the devices. You can also locate it in a specific area (in my case “living room”) to be able to differentiate it in case you have different hubs to control different areas.
Once you have added the hub, you can start scanning the QR codes of the devices that will form the security system.
As you can understand, if you have turned off the hub, the app will not be able to add new devices.

Configure the Ajax security system

In order to configure the system, the first thing to do is connect the base (hub) that will control each sensor. Although it is obvious, we have to state that to be able to do it successfully, it is necessary to have –from the beginning- the hub connected to the network, so that it can make the connections to verify the legitimacy of each sensor.

If the base is connected to the internet, the name will light up green. If it is not connected, it will light red.

On the back of the product box we can find the main specifications of the system:

As specified, you can have up to 50 different users, with 100 connected devices and 25 cameras or video recorders. Its range is 2 KM, it has a backup battery with a duration of 16 hours (in case the power goes out -or it is cut off) and it has an Ethernet connection and two 2G SIM slots, so that it can send alerts even when there is no data connection, through telephone messages.

The product includes not only the connection cable but also the network cable to connect it to the router.
The back cover detaches to make connections.
In the image you can see the QR code to add it to the app, the power button and the two SIM slots

Once the Hub is correctly connected to the power and to the router, we can start adding other devices to connect them.

Elements of the Ajax security system

Robustness of the devices

Each device to be fixed to the wall has a rear cover that makes it very difficult to access the inside of the apparatus. They all bring their complete set of screws, dowels, etc. so that there is no doubt about how and with what to fix them to the wall.

In addition, Ajax offers its products in a black or white finish, so that they can be easily integrated into any environment and go unnoticed.

These are the products we have tested:

Hub 2

We have already covered its function and appearance extensively, so we will not dwell on it further. It is the nerve center of the Ajax home alarm system

Movement detector

The motion detector, in addition to the sensor, includes a camera that records a short clip that it automatically sends to your phone so you can see who is in the room.

This is the back of the motion sensor, with the Smart Bracket that protects all accesses removed.

Door / window opening detector

Made up of two pieces, one that is attached to the wall and the other to the door, when separated it causes the alarm to go off.

Smoke Detector

Useful in older homes, where structures and pipes may be deteriorated, or for areas with nearby warehouses

Flood detector

If you are going to put the Ajax surveillance system in a house that is empty for long periods of time, you are interested in putting this type of detectors that will suddenly warn you that the humidity level is triggered in a certain room (the most normal is that it is in a bathroom or kitchen, where most of the pipes run)

Indoor siren

If you are in a large house, where there may be uninhabited areas (such as in a chalet) you are interested in having an audible alert that the alarm has been triggered so that you are alert that an intrusion has occurred.

We have tested it and without being thunderous, it is more than enough to trigger the alert of the inhabitants of a house (and maybe even to deter the intruder). When it is connected it has a lit led.

Touch keyboard

To have it near the sofa or in the bedroom and to be able to activate or deactivate the alarms without having to go to the app (so it can be handled by other people who are not identified in the application).

Remote control

Another alternative to be able to activate and deactivate the alarm without having to go to the control panels or the app- It is perfect to attach it to the keys and never forget to remove or put it.

Panic button

It is possible that for many it sounds like a movie, or that the size of the house makes it unnecessary to put a panic button in a room, but if young children or elderly people are at home and you want to make sure they feel protected, you are interested in putting this button nearby so they can push it if they feel threatened.

Smart plug

Use this plug to connect devices that you can turn on and off at will, such as a lamp, or a television, so that you can offer the feeling that there are people in the house and throw off those who may be watching to find out routines.

Other considerations

The operating system it uses is Malevich

In the app there is a complete help system to understand how they work and how to configure the different devices.


The Ajax system is a professional alarm system that offers everything you could ask for and / or need, with all the security, privacy and efficiency guarantees you could ask for.

Its modular system allows you to design the system to measure, with the assurance that the initial hub that will manage everything will not be too small when your needs grow.

The design is clean, aseptic and functional, and although -as we have said- they still have to work on the usability aspect if they want to be implemented in the domestic sector -without the need to resort to a professional installer, configure all the system devices we it took a couple of hours.

If you still don’t want to “get your hands dirty” you can turn to Ajax’s professional sales network.

Its big “downside” is that it is not yet integrated with HomeKit, although the voting page for the most desired characteristics of its users is number one, so it is to be hoped that it can soon be managed from the smart home system of Manzana.
