How to set up Ajax PRO Desktop and the Ajax PRO app

Applies to: Ajax PRO Desktop and the Ajax PRO: Tool for Engineers mobile app (iOS and Android), used with Ajax hubs such as Hub 2, Hub 2 Plus and Hub BP. Screens differ between app versions, so check the Ajax manual for your version.

Quick answer: Ajax PRO Desktop and Ajax PRO: Tool for Engineers are Ajax's installer apps. Download them only from Ajax's official pages or the app stores, then create a PRO account. Your customer's Ajax Security System login will not work. Add the hub by its 20-digit ID, or ask the hub admin to invite you. Installer access to hub settings is time-limited unless the admin grants permanent access. Everything runs through Ajax Cloud, so the hub must be online.

Ajax PRO Desktop is Ajax's desktop app for installation companies, service companies and monitoring companies. Ajax's manual says you can use it to configure and test devices, manage user access, and monitor and process events and alarms, for an unlimited number of systems. It can be used alongside the Ajax PRO mobile app, which Ajax describes as an app for installers and security service providers.

This is the Ajax equivalent of the remote servicing or UDL software used with other alarm brands. There is one big difference. Ajax has no documented USB, serial or local programming route. You configure the hub through Ajax Cloud, and the hub owner or admin controls how long you can change settings.

Before you start

An Ajax hub that is connected to the internet. We stock the Ajax Hub 2 (4G) Jeweller, Hub 2 (2G) Jeweller, Hub 2 Plus Jeweller and Hub BP Jeweller. The PRO apps work only with Ajax equipment.
Hub BP Jeweller connects over cellular only and has a battery saving mode. Before you configure it remotely, wake it with a scheduled wake-up or an SMS wake-up (set up in the PRO apps). Battery and wake-up settings are only available in the Ajax PRO apps.
The hub's 20-digit ID. It is printed under the QR code on the hub.
For PRO Desktop on Windows: Windows 10 64-bit as a minimum (Windows 11 64-bit recommended), an Intel Core i3 (8th Gen or later) or AMD Ryzen 3 (1000 series or later) processor, 8 GB RAM (16 GB recommended), 2 GB free storage (8 GB recommended), an OpenGL 2.1 graphics driver and a 1600x900 screen or larger.
For PRO Desktop on a Mac, the manual lists macOS Big Sur 11.6 or later, an Apple M1 chip or newer and a 1440x900 screen or larger (macOS 15 Sequoia and an M3 chip recommended). Ajax's manual says PRO Desktop is available for macOS, but the download page we checked listed only Windows x64. If you need the Mac version, ask Ajax support.
For the mobile app on iPhone: iOS 18.0 or later, according to the App Store listing.
An email address or phone number for your PRO account, and the hub owner or admin on hand to approve your access.

Step 1: Download the right Ajax app

For a PC, open the Ajax software page or the Ajax PRO Desktop page and download Ajax PRO Desktop. Avoid third-party download sites.
Open the installer and follow the prompts to install it.
For a phone, install Ajax PRO: Tool for Engineers from the App Store or Google Play.
Do not install Ajax Security System or Ajax Desktop for installer work. Those are the end-user apps.

Step 2: Create and secure your PRO account

Open either PRO app and choose Create PRO account.
You can use the same email or phone number as a user account, but the PRO account is a separate account with its own login.
Sign in. The same PRO account works in both PRO Desktop and the PRO mobile app.
Turn on two-factor authentication. It is optional, but worth doing.
Check the list of active sessions and end any you do not recognise.

Step 3: Add the hub to Ajax PRO Desktop

In PRO Desktop, add a new space and choose to add a hub.
Enter the 20-digit hub ID printed under the QR code.
If you create the space and add the hub yourself, you have unlimited time to configure the system. Once an admin is added, you keep access for another 8 hours.
If the customer already runs the hub, ask the admin to invite your PRO account from their app instead.

Step 4: Request installer access to settings

An admin invitation gives you configuration rights for 8 hours. After that, settings are blocked until you request access again.
To request access, tap or click the lock icon, then Access rights > Request access.
Choose 1, 2, 4 or 8 hours, or permanent access.
The admin gets a push notification and approves it. Approval usually applies within about a minute.

Step 5: Set up your company and engineers (optional)

Create a Company and choose monitoring, installation or both. The person who creates it becomes the company owner. For an installation company the owner also gets the head of installers role, and for a mixed company the owner gets both head of installers and head of operators.
Add employees by the email address of their existing PRO accounts and give each one a role.
Create settings templates for standard jobs. A company can hold up to 100 templates.
Assign installers to objects. Installers can change settings only after the head of installers grants access.

Step 6: Configure and test devices

Pair wireless devices, such as the Ajax KeyPad Plus Jeweller, by scanning their QR codes in the PRO app.
If you are working on an Ajax hybrid hub with Fibra lines (such as Superior Hub Hybrid), use the Fibra line scan. Ajax says it finds devices on the line and pairs them with the hub. The Hub 2, Hub 2 Plus and Hub BP hubs listed above are wireless (Jeweller) hubs, so this step does not apply to them.
Use the setup wizards where your app version offers them.
Test each device and check events in the event log before you leave site.

How Ajax PRO connects to the hub

PRO Desktop connects to Ajax Cloud over the internet. A green indicator means it is connected. Red No Connection means it is not.
The hub reaches the cloud over Ethernet, Wi-Fi and/or cellular, depending on the hub model.
Ajax says its apps talk to the hub via the server, so you cannot operate the hub from the apps if its internet connection fails. The hub keeps working on its own and stores events in the meantime.
Ajax Translator can pass events from a hub straight to a monitoring station's software. It handles events only, not configuration.

Ajax PRO apps vs the end-user apps

App	Who it is for	Account
Ajax Security System (mobile)	System owners and users	User account
Ajax Desktop	System owners and users on a PC	User account. It does not accept PRO accounts.
Ajax PRO: Tool for Engineers (iOS, Android)	Installers and security service providers	PRO account
Ajax PRO Desktop	Installation, service and monitoring companies, and multi-site businesses	PRO account

Owners do not need a PRO account. The PRO apps add things the user apps do not have. These include multi-site management with search and filters, a non-editable event log, company roles and templates, a monitoring module and video wall in PRO Desktop, PDF maintenance reports, and CSV export of object, device and event data. The hub admin keeps control. From the user app they can restrict what a company may do, disable its access or remove it.

Good habits for Ajax remote servicing

Agree access with the customer before the job, so the admin is ready to approve your request.
Request only the hours you need. Keep permanent access for sites where it has been agreed.
Turn on two-factor authentication and review active sessions now and then.
Use company templates so every engineer sets up systems the same way.
Set connection-loss alerts for each channel under Hub > Service > Server connection, with a delay of 3 to 30 minutes.
Keep the PRO apps updated. The Android app updates through the Play Store.

Troubleshooting

Problem	Likely cause	What to try
Cannot log in to the PRO app	You are using an Ajax Security System user login	Create a PRO account. You can reuse the same email or phone, but it is a separate account.
Ajax Desktop rejects your PRO login	Ajax Desktop is the end-user app and does not accept PRO accounts	Install Ajax PRO Desktop instead.
Settings locked after a visit	Your 8-hour access has ended	Send a new request via the lock icon. Ajax support cannot restore access for you. Only the hub admin or a PRO with full rights to configure the system can grant it.
Red No Connection in PRO Desktop	The PC cannot reach Ajax Cloud	Check the PC's internet connection.
Hub shows as offline	The hub has no internet link to Ajax Cloud	Check the hub's Ethernet, Wi-Fi or cellular connection on site. Remote setup is not possible until it is back online. For Hub BP, check whether it is in battery saving mode and wake it before you make changes.
Hub not found when searching your object list	Hub ID not typed in uppercase	Enter the hub ID in uppercase when searching the object list, as Ajax's manual instructs.
Cannot attach a hub by ID	Hub is offline, already has admins or PROs, or belongs to another company	Ask the hub admin to invite you instead. This rule comes from a 2022 Ajax article, so check the current manual.
PRO Desktop will not install	PC runs Windows 7, Windows 8 or 32-bit Windows	Use a 64-bit Windows 10 or 11 PC, or ask Ajax support for version 4.24.
Sessions you do not recognise	Possible unauthorised access	End the unknown sessions and turn on two-factor authentication.

Questions

Is Ajax PRO Desktop free, and where do I download it?

Ajax does not publish a price for PRO Desktop that we could find, so check with Ajax. The iPhone app, Ajax PRO: Tool for Engineers, is listed as free on the App Store. Download PRO Desktop only from Ajax's own software or PRO Desktop pages.

Why can't I log in to Ajax PRO with my Ajax Security System account?

PRO accounts are separate from the user accounts made in the Ajax Security System app. Create a PRO account in either PRO app. You can use the same email or phone number.

How do I get installer access to a customer's Ajax hub?

Ask the hub admin to invite your PRO account, or add the hub by its 20-digit ID if it has no admins yet. To change settings later, use the lock icon, then Access rights and Request access. The admin approves it from their app.

Why does my Ajax installer access expire after 8 hours?

An admin invitation gives configuration rights for 8 hours. After that, settings are blocked until you send a new request. You can request 1, 2, 4 or 8 hours, or permanent access, and the admin decides.

Can I program an Ajax hub without internet or by USB?

No route is documented. Ajax apps talk to the hub through the Ajax server, so you cannot operate the hub from the apps without internet. The hub keeps working on its own and stores events until it reconnects.

What are the system requirements for Ajax PRO Desktop?

On Windows, Ajax lists Windows 10 64-bit as the minimum, with an Intel Core i3 (8th Gen or later) or AMD Ryzen 3 (1000 series or later) processor, 8 GB RAM and 2 GB free storage. Windows 11 64-bit and 16 GB RAM are recommended. The manual also lists macOS Big Sur 11.6 or later on an Apple M1 chip or newer.

What if my PC runs Windows 7 or 32-bit Windows?

From June 2025, new versions no longer support Windows 7, Windows 8, 32-bit Windows or macOS Catalina. Ajax says version 4.24 is the last one for older systems, and support can provide it on request.

Do I need to be an Ajax partner to use the PRO apps?

Ajax does not state a dealer requirement for the download or the PRO account. Its manual does say Ajax Services need dealer registration and are not available in every country, so check Ajax's Ajax Services availability tool for your company.

Does Zenith install Ajax systems or issue Ajax software licences?

No. We supply Ajax hubs, detectors and keypads, but we do not install them or issue software licences. If you need an engineer, use our find a CCTV installer page. Installers can apply for a trade account.
