Very reliable system, app and hardware
Very reliable system, app and hardware.
Only hiccup with hardware was to learn to clean the fire detector sensors. That took couple of tries. Software wise along the way for some odd reason I lost the ability to rename rooms. I sent ticket to tech support and they responded quickly. Turned out I had lost some of my system admin rights along the way (even though the app said I had full rights). Disabling permissions and enabling them again via another system administrator account resolved the matter. Now I have correct rights.

Outstanding support – extremely satisfied!
I ran into a technical issue with my Ajax security system (a firmware mismatch between the hub and the range extender, which caused several fire detectors to go offline). The IACS support team helped me resolve this exceptionally well.
What impressed me most:
- Very courteous and patient – every question was taken seriously and answered thoroughly
- Detailed, easy-to-follow instructions – step by step, so I could understand and fix the issue myself
- Fast, competent diagnosis – the root cause was identified accurately, without unnecessary detours
By the end, not only was my technical problem solved, but I also felt genuinely well taken care of throughout the whole process. Especially with safety-critical equipment like fire detectors, it's reassuring to have a support team that truly cares.
Highly recommended – thank you for the great support!

I'm quite satisfied
In general, I'm quite satisfied with the Ajax alarm system. It’s certainly not the cheapest option out there, but the peace of mind it offers without recurring subscription fees makes it completely worth it. The system is rock solid, and while I rarely need customer support, whenever I do reach out, they are fast, responsive, and extremely helpful. I previously installed a system at my mother-in-law's house, and I'm so pleased with it that I'm buying a new one for my own place now.

Login details lost
I had lost my login details and firstly with many attempts to get logged in my account was put on a temp block which is appreciated as a precaution measure. They then helped me recover my login details and kept in touch every step of the way while getting me up and running again. Great work AJAX team.

Top-tier security with no competition!
Hands down the absolute number one on the market. Ajax completely blew me away – setup and pairing take just a few minutes, the app runs lightning-fast, and the customization options are unbelievable. With a massive range of sensors (from motion and water leak to smoke detection), you can build a system tailored exactly to your needs. Everything runs reliably, with zero false alarms and a total sense of security. Extremely satisfied, I wouldn't change a thing!

Very good security system without the need for professionals.
I bought lots of Ajax devices a couple of months ago and I am very happy with the purchase. The installation and verification procedures were easy and can be performed by yourself (you should really carry out the describe tests, though).
The system is easily configurable, the support is fast, friendly, and thorough, hope it stays that way.

I am thoroughly impressed
I am thoroughly impressed. We install these system in the US and, besides the "learning curve" of some the European names for certain items and functions, these systems operate near-flawlessly. The technical support is truly second-to-none that I've dealt with for nearly 40 years in this business.
If you are considering a new system to stock, install and maintain I highly recommend Ajax Systems. Being a tech-person I appreciate that their responses are, quick and includ great details which are clear and and concise.
Fantastic!
