Why Ajax


What can I make my Ajax system do?

Ajax can be easily expanded with entry, fire and flood detectors, as well as relays for managing electrical appliances remotely. You can purchase and add additional devices to the system individually. Detectors can be connected with a few taps in the mobile app.

Do Ajax devices really work that far away from the hub?

We've tested the maximum distance between the hub and detectors in open space, and it really does reach 2,000 meters. Your experience may vary, since walls, ceilings and other barriers will shorten that distance. If you’re unsure, you can do a radio test using the Ajax Security Systems app to determine the signal strength before you install detectors.

How often do device batteries need to be changed?

Ajax devices are powered by batteries, not from the network, which is how wired systems work. With that in mind, we developed a special energy-efficient radio protocol that keeps them protecting your home or office for as long as possible— up to 7 years.

How will I know if a device battery is dying?

Once the battery reaches a critical level, Ajax will send you a notification. If you’re curious, you can always double check battery levels at any time in the device settings.

How do I monitor the Ajax security system?

The easiest way to monitor is to use the Ajax Security System application for iOS and Android. The app will let you arm/disarm the system and keep tabs on your devices (including information on signal status, battery level and temperature). The system can also be controlled with Ajax SpaceControl and/or KeyPad.

Will my cat or robot vacuum set off an alarm?

Ajax devices use a digital algorithm to detect human movement. As long as your pets are smaller than 50 centimetres (19.5 inches) and 20 kilograms (44 lbs), they shouldn’t set off your Ajax detectors.

Can I add and remove system users?

Yes, if you are an administrator with full access to the system settings. You can add up to 50 users to the Ajax hub. They can be family members, friends, neighbours, colleagues or even a security company.

Does Ajax support video surveillance?

Third-party cameras can be connected to the Ajax using the app. You can choose nearly any camera, as long as it supports RTSP video streaming.


How does Ajax let me know about an emergency?

Ajax sends alerts using push notifications, SMS messages or calls to the system owner. You can choose your notification preferences in the mobile app.

How does Ajax sent alerts so quickly?

The hub constantly monitors the detectors, and they regularly report back to the hub. If a detector is triggered, it immediately transmits that information. The hub then sends an alert to the system owner's smartphone and/or to a central monitoring station. All of this happens in just milliseconds.

Preventing sabotage

What happens if the internet goes out?

In offline mode, Ajax operates the same way other professional security systems do: detectors monitor the situation and send information to the hub. If there's any danger, the system sirens will let you know.

If there’s a blackout, will I be left unprotected?

No. Ajax will continue guarding your home, even during blackouts. All of the detectors operate on battery power, and there's a backup battery installed in the hub. It provides up to 16 hours of reliable operation. Once your home regains power, the hub will automatically recharge the backup battery.

Can Ajax be hacked?

Ajax has a closed ecosystem. We have eliminated breaches and failures by replacing standard algorithms and solutions with own inventions. We develop software by ourselves and we have created Jeweller radio communication technology featuring multi-level protection from scratch. The Hub OS Malevich real-time operating system is immune to viruses, and our own IoT protocol eliminates the feasibility of our equipment being used within botnet networks. To prevent effectively any future attacks, we regularly conduct penetration tests involving external auditors.

Can Ajax be jammed?

Unlike most wireless and wired security systems, Ajax uses dual communication channels to send alerts— cellular communication and broadband internet. When there's a problem with one of the channels, Ajax automatically switches to the other. If an attacker jams the GSM signal, the system sends an alarm using Ethernet or Wi-Fi.

Can the radio signal between the hub and devices be jammed?

Not without being noticed. The hub controls all system detectors. The moment it fails to receive a signal from at least one of them, an alarm is sent to inform users about the communication loss. Additionally, the hub reports on high noise levels on the radio channel, which may point to deliberate jamming attempts or other powerful interference. For example, a neighbour's faulty radio receiver.

Can Ajax radio signals be intercepted?

No. All device data is encrypted with a floating key algorithm before being sent. For additional protection, each device has a unique identifier that helps prevent forgery.

Do I need a professional installer to set up the system?

If you want, you can set the system up on your own— the mobile app has interactive instructions with prompts. On the other hand, a professional installer can set everything up optimally to ensure maximum protection. The choice is up to you.


What information does Ajax collect and why?

Ajax only collects data that helps the system perform its functions and improve its capabilities. The data is fragmented, anonymized and encrypted across several servers in Europe. It enters the server via an encrypted channel and cannot be used without user permission.

Ecology and Health

I heard that radio signals can negatively affect a person's health, especially men. Is there any truth to that?

There are a lot of things that negatively affect a person’s health. Among these are a sedentary lifestyle, substance/alcohol abuse or a bad diet. Our equipment is none of those things. And, in addition to being people-friendly, our devices are eco-friendly. We even have the EU certificates to prove it.


Who responds to an alarm if I’m not home?

In theory, you could give your neighbours system access. That way, they'll also receive alerts and can check to make sure everything is okay. That said, we would recommend giving that responsibility to security professionals— Ajax works with central monitoring stations around the world.

How much does Ajax cost to operate each month?

Ajax is free to operate when you use it yourself to self-monitor. You'll only need to pay a monthly fee if you connect to a central monitoring station. The cost will depend on where you're located, the size and type of premises and the number of requested services.
