Outstanding system — years ahead of the competition
Ajax alarms are fantastic; they genuinely feel years ahead of other alarm manufacturers in almost every aspect.
The hardware is sleek and well-built, and the app is brilliant — fast, intuitive, reliable, and beautifully designed. The entire ecosystem integrates seamlessly, and the battery life on the devices is incredible.
Customer support is also second to none. When I contacted them, I was helped almost immediately by a knowledgeable, friendly team who provided clear links to great documentation and video guides. Everything was straightforward and easy to follow. Excellent all round.

Defective sensor
We had an issue with one of the sensors: the battery was empty after only 3 months
They were changed immediately but after another 3 months it was the same
After contacting technical support they came 2 days later and changed the sensor which appeared to be defective
Kudos to our contact Thomas and your excellent service
So yes, I will definitely (and already have done so) recommend Ajax Security 👍🏼👍🏼👍🏼

I highly recommend the Ajax alarm system. The equipment is truly top-of-the-line, offering excellent reliability, ease of use, and outstanding performance. The mobile app is intuitive, and the overall quality of the system is impressive.
A special mention goes to the technical team in Porto, Vila Nova de Gaia. Their professionalism, technical expertise, and customer support have been exceptional throughout the process. Fast, knowledgeable, and always willing to help.
If you are looking for a premium security solution, Ajax is an excellent choice.

I replaced my old ADT system two years…
I replaced my old ADT system two years ago with an Ajax alarm. I am so happy I made the move. Gone are the monthly charges for no apparent service and the fact that when the alarm went off, a family member was called. This is both more reliable and five times more user-friendly. And I don't need a dedicated land line, etc. I've had one issue, which was a technical issue on my part. I emailed the question to customer support and received a reply within 10 minutes. Solved. Can't recommend them highly enough.

Potential, but that's where it ends
I have invested heavily in AJAX over the last year, from sensors, cameras, range extenders, switches, relays - most of the AJAX offering is installed.
I am disappointed. There are two areas pulling AJAX down. 1) Their cameras are advertised and pictured outdoors, however the 8 cameras I have have mostly all failed within 1 year from bolts rusting, the rubber waterproof gaskets failing (not being UV stable), and camera lenses distorting (not being UV stable).
2) Their software (application support team) does not take customer feedback. A year later and the AJAX app still does not offer simple flexibility like sorting devices in any other way than the date it was installed. No sorting or grouping on the dashboards either, and the app remains ONLY security focused where automation/switch activation is always an afterthought and cannot be set as the loading page, even if these functions are used multiple times a day.
I took a chance on AJAX and I am underwhelmed.

Hello Nicholas!
Thank you for sharing such detailed and honest feedback. We’re sorry to hear that your experience has not met your expectations, especially after such a significant investment in the Ajax ecosystem.
We take your concerns about the outdoor cameras very seriously. Issues with corrosion, seals, and lens performance are certainly not the experience we want our customers to have, and we recommend contacting our support team so each affected device can be assessed individually.
We also appreciate your detailed feedback regarding the app, particularly device sorting and grouping, dashboard flexibility, and automation access. We understand how important these everyday usability features can be, especially when the system is used extensively. Your suggestions are valuable and will be shared with our development team for consideration.
Thank you for giving Ajax a chance and for taking the time to explain where we can do better.
Best regards,
Max Brin
