On controlling your security system with an Android smartphone


To one space you can add:

  • up to 200 users;
  • up to 50 rooms;
  • up to 25 security groups.

No, you need an Ajax hub to connect a system to monitoring software.

Other features do not depend on the adding of a hub to the space, including the Control and Rooms tabs and quick access to automation devices.


You can add an unlimited amount of Yale smart locks to one space.


To one space you can add:

  • up to 200 standalone cameras, including third-party and Ajax cameras;
  • or up to 14 Ajax NVRs with a total of 224 channels. Both 8- and 16-channel NVR versions can be used.

Each camera or NVR can be added to only one space.

Third-party cameras require an Ajax hub for connection and can transmit only an RTSP stream without access to the archive.


Only one hub can be added to one space.


No, you only need to update your app:

Features will remain the same, including the Control and Rooms tabs and quick access to automation devices.


Space is a virtual entity where various autonomous devices located on the same physical object are gathered. To create a space, a user does not need an Ajax hub. Devices are added to a system according to the needs of the facility.

You can add a hub with detectors, only NVR with cameras, only Ajax cameras, smart locks, or combine all these devices into one system.

The space concept offers flexibility for customizing the system according to the specific needs of the facility.


No such option is provided for. Deleting security system events is prohibited under the requirements of EN 50131.

The panic button is available in the space regardless of the hub presence.


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 13.0 and later for iOS
  • Ajax Security System 5.0 and later for Android
  • Ajax PRO 13.0 and later for iOS
  • Ajax PRO 5.0 and later for Android
  • Ajax PRO Desktop 2.5 and later for Windows and macOS

When hub loses the connection with the server, Ajax apps can notify the users using a standard push-notification sound or a siren sound (enabled by default).

To disable the siren sound when hub loses the connection with the server in the Ajax app:

  1. Go to Service settings of the hub (Device HubSettings Service).
  2. Select menu item Server Connection.
  3. Enable the option Receive events of server connection loss without alarm.

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 HubSettings Users → User Settings ).


To delete a group:

  1. Go to group settings (HubSettings 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 (HubSettings 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 (HubSettings 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 (HubUsers → 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 need to click on the Number field, enter the balance check USSD code (available from the mobile phone service provider).
