## What is Ajax Security System?

BUILD YOUR OWN SECURITY AND COMFORT WITH AJAX

A SINGLE INTEGRATED ECOSYSTEM 
Ajax is a unified ecosystem in which intrusion protection, video surveillance, fire safety, water leak prevention, and automation work seamlessly together. You can add new devices and scale your system as space requirements grow — without compatibility issues, complex setup, or redesigning everything from scratch.

INSTANT ALERTS WITH VISUAL PROOF
You don't miss important events — you know exactly when and how to respond. When an intrusion, fire, or water leak is detected, the app sends a critical alert that breaks through Do Not Disturb mode. Visual alarm verification from Ajax cameras or MotionCam detectors helps you quickly understand what's happening on site.

VIDEO SURVEILLANCE YOU CAN TRUST
Watch live video or browse the archive directly in the app. Footage is synchronized with system events, giving you a clear visual context for every alarm and complete situational awareness. To protect your privacy, video streams use secure proprietary transmission technology, while passwordless camera authentication minimizes the risk of unauthorized access.

AUTOMATION FOR ENHANCED SECURITY AND ROUTINES
Set your system to operate automatically. Change security modes on a schedule, turn on lighting when motion is detected, shut off water in case of a leak, or control locks, gates, heating, and appliances. Automation scenarios run in the background — even without an internet connection — while you focus on your day.

PROFESSIONAL RESPONSE, ONE TAP AWAY
Connect your system to a monitoring company to access professional security services with fast alarm response. The largest alarm receiving centers and a wide range of CMS software in more than 180 countries support Ajax systems. In an emergency, press the in-app panic button to instantly transmit the event and your smartphone's location to the rapid response unit.

### 1/5 — Lost ability to remove user from my system

*2026-08-09, version 3.53*

All of a sudden we can’t remove a user from our system on either version 3.52 or 3.53. Tried on both our phones.

### 5/5 — Brilliant

*2026-08-04, version 3.53*

Brilliant system. DIY installed in about 1.5hrs - emergency, as previous system packed up just prior to my holiday. 

Improvements - battery only doorbell cam and make cloud recording available to us DIY’ers as well please, not just through professional installers/companies.

### 5/5 — Top Alarmanlage

*2026-06-25*

Seit 2019 arbeitet eine Ajax Alarmanlage in unserem Haus. Bei verbauten 47 verschiedenste Sensoren mussten nun nach 7 Jahren die meistbenutzten Sensoren eine neue Batterie bekommen. Nein sie waren nicht leer und es gab auch keine Meldung. Präventiv erneuerten wie sie. Es waren ganze 5 Batterien, die nur noch einen Strich von 3 hatten. Die allermeisten haben immer noch 3 Striche und wenige 2 Striche einmal wöchentlich werden alle Sensoren geprüft. (Beispiel Fenster auf schauen ob es einen Wechsel gibt und Fenster zu und wieder schauen ob es einen Wechsel gibt. )
Das finde ich schon absolut klasse was die Ukrainischen Ingenieure da geleistet haben. Hut ab.

**Developer response:** Hallo!
Wir sind dankbar für Ihre Bewertung! Ihr Verbesserungsvorschlag wird an unser F&E-Team weitergeleitet.
Wir wünschen Ihnen weiterhin eine angenehme Nutzung!

### 5/5 — Best security system ever ⭐️⭐️⭐️⭐️⭐️

*2026-06-06, version 3.49*

This system & app is a game changer fully protecting my gardens, garage & home.

Started with a basic setup and now had over 30 devices active including heat & smoke sensors.

Love how you can customise everything fine tuning the setup.

Still can’t believe how good the battery life is on the sensors & sirens.

Recommend 100% ⭐️⭐️⭐️⭐️⭐️

### 5/5 — Zuverlässigkeit

*2026-06-05*

Zuverlässiges System. Melder, die nicht kabelgebunden mit der Zentrale kommunizieren, arbeiten zuverlässig. Seit Jahren keine Störungen. Batterieaustausch i.d.R. nach 3-4 Jahren selbst durchführbar.

**Developer response:** Hallo,
Vielen Dank, dass Sie sich die Zeit genommen haben, uns über Ihr Benutzererlebnis zu berichten.

### 5/5 — De plus en plus complète

*2026-05-31*

L’appli a parfois du temps de réponse. Elle évolue avec le temps et comporte toujours de nouvelles fonctionnalités.

**Developer response:** Bonjour,

Merci pour votre retour et pour votre confiance. Nous sommes heureux d’apprendre que vous appréciez l’évolution continue de l’application et l’ajout régulier de nouvelles fonctionnalités. Nous prenons également en compte votre remarque concernant les temps de réponse occasionnels, car l’amélioration des performances reste une priorité pour notre équipe.

### 5/5 — Très satisfait de cette application

*2026-05-20*

Il est facile de tout programmer, de sélectionner plusieurs utilisateurs avec des accès de niveaux différents.

**Developer response:** Bonjour,

Merci beaucoup pour votre avis. Nous sommes ravis d’apprendre que vous appréciez la simplicité de programmation du système ainsi que la possibilité de gérer plusieurs utilisateurs avec différents niveaux d’accès. Nous concevons nos solutions pour offrir à la fois flexibilité et facilité d’utilisation, et votre retour nous confirme que nous allons dans la bonne direction.

### 4/5 — Système au top !

*2026-05-20*

Quasiment rien à redire. Énormément de possibilités de gestion des droits, des comptes, des espaces. Juste un truc qui semble absent : la possibilité de réorganiser l’ordre des dispositifs… Quand on veut couper rapidement la sirène d’un détecteur incendie (par ex), faut scroller jusqu’au bon endroit dans la longue liste… pas pratique du tout. D’où, une étoile en moins.
Edit : je viens d’acquérir une Doorbell. Lorsque je reçois une notification, j’aurai aimé via un appui long sur la notif sur l’écran de veille de l’iPhone, faire apparaître directement l’image que l’on retrouve dans l’onglet notification de l’appli. Gain de temps et réactivité… Merci à vous.

**Developer response:** Bonjour
!

Merci beaucoup pour votre retour détaillé et pour avoir partagé votre expérience. Nous sommes ravis que vous appréciez les nombreuses possibilités de gestion offertes par le système. Nous prenons également bonne note de votre remarque concernant la réorganisation des dispositifs dans la liste — ce type de retour est très utile pour nous aider à améliorer l’expérience utilisateur.

### 4/5 — Great System

*2026-05-09, version 3.47*

Great system and the app is so far easy to use. Would be great if you could change the order in which the ‘my devices’ is displayed. Also would be great to see a widget option for IOS users that would give me the remote options so I didn’t have to open the app each time.

### 5/5 — 12 months on

*2026-05-02, version 3.47*
