Ajax apps can be installed on a smartphone from App Store or Google Play. If you don’t have such applications, you can download the installation APK file of the Ajax app through specialized services.

We do not guarantee the correct operation of Ajax apps downloaded through third-party services.

Please, check that the Allow installing applications from unknown sources option is enabled in the smartphone’s settings (depending on the phone model, the option name may vary). When enabled, run the downloaded APK file to install the app.


Two-factor authentication is supported by the following apps:

  • Ajax Security System 2.14 and later for iOS
  • Ajax Security System 2.17 and later for Android
  • Ajax PRO 1.7 and later for iOS
  • Ajax PRO 1.7 and later for Android
  • Ajax PRO Desktop 2.5 and later for Windows and macOS

Most likely, several users are receiving SMS alerts. For example, if three people receive SMS alerts, then each notification is sent out three times.


We would like to recommend you to activate SMS and calls in case of alarms. SMS and calls can be activated in User settings (Ajax app Devices Hub Settings Users User Settings ).


The user identifier is a unique number which is assigned by the hub to the specific user being added.

If the user has several hubs, they will be assigned their own unique number in each hub

Your own user identifier can be found in the profile settings (Hub Settings User settings ).

Your identifier and combinations for using the keypad personal password are displayed in the settings menu.


To delete a group:

  1. Go to group settings (Hub Settings Groups).
  2. Select the group, move all devices to other groups.
  3. After there are no sensors and devices left in the group, you can delete it by the group settings .

At the moment, it is impossible to delete all groups from the hub. To completely remove all groups, the hub must be returned to the factory settings!


To disable the group mode, go to groups settings (Hub Settings Groups) and deactivate the group mode.


The ID of the group is a number of the group, which is necessary for arm separate groups from the keyboard.

The group number (ID) is displayed in the group settings (Hub Settings Groups)


In hubs with the firmware version OS Malevich 2.6 and latest hub administrator can limit the user’s access to the following functionality:

  • Night mode activation (perimeter security)
  • Panic Button
  • View cameras
  • Turning on/off automation devices
  • View devices and rooms
  • View notifications

All these settings you can find in the user’s settings (Hub Users User settings ).

The rights to the group, viewing notifications, devices and rooms can only be removed from the user account!


The second IP address is a backup in case of direct connection to the Central Monitoring Station (CMS).

If the main IP address is not available, the hub uses the second IP address to send events.


The direct connection (Monitoring Station tab) is the channel used to transmit hub events directly to the Central Monitoring Station (CMS) of the security provider, bypassing our server.

When direct connection is used, all events are communicated directly to the security company’s central monitoring station without affecting the functioning of the Ajax apps. If the direct connection is lost for any reason, the server acts as a redundant communication channel.


You can connect any IP camera using RTSP to the Ajax security system. In total, you can connect up to 10 cameras to Hub, up to 25 cameras to Hub 2, up to 50 cameras to Hub Plus, and up to 100 cameras to Hub 2 Plus.

Dahua cameras and video recorders can be added by scanning their QR codes (similarly to Ajax devices). And EZVIZ, Hikvision and Safire video surveillance systems can be added to the hub with a few clicks. So you don’t have to waste time on setting up network equipment.

Video recorders allow you to bypass the limit on the number of video surveillance devices that can be connected to the hub. The video recorder is a single device to which you can connect multiple video cameras. The video stream from each camera will be available in the Ajax app.


You need to click on the Number field, enter the balance check USSD code (available from the mobile phone service provider).

After entering the number, click “Check balance”. It takes about a minute to complete the request. After the query is executed, you will see the status of the SIM card account.

The access to the Ajax web application was closed on October 30, 2018.

In January 2018, a warning was added to the web application:

We’re announcing that we will be shutting down Ajax web app soon. We had ambitious ideas to make the multifunctional platform for the web browsers. But along the way, we have created mobile apps, which became the most popular way to control Ajax security systems for our users. And since it is a lot faster to launch new features through mobile apps, we decided to focus all our energies and resources on it.

Soon we will present a new Ajax Desktop app for PROs. With its help security firms and engineers will be able to monitor hubs and provide service remotely. All other users can still control their Ajax security systems through mobile apps for iOS and Android.

We have developed the Ajax PRO Desktop application for PC. It is secured, protected, TLS-encrypted, and it has all the features of the Ajax PRO: Tool for Engineers mobile application.
