It took us sometime to fine tune the sensitivity and the direction of the detection devices. Indeed, they were reacting when domestic animals were circulating by night or when lawn mower robot was passing by. That was triggering the alarm very often! The installer was not of a great help. Consequently I was obliged to fine tune the sensitivity (down to low) and the direction myself to minimize false alarms. After one month use devices are working very well and the system is providing us a great peace of mind as they are also connected to a professional security house (ESG) that I wish hereby to thank as well. As the installer is no more answering his phone or extending any help I’m looking for another one accredited by AJAX (particularly for system expansion, maintenance or changing the batteries): you could be of help. Thanks so much
Following Ajax reply, who did not leave a link to connect with them, I confirm that I accept their proposal: « assistance in finding another accredited Ajax installer for system expansion, maintenance, or battery replacement, our support team will be happy to help me connect with a certified partner in my area » and I do hope Mr Max Brin from Ajax would connect with me for coordination. thanks to relay my message

I would like to thank the technical team
I would like to thank the customer service for the great help they provided me. I had a problem with a non-functioning siren and I knew nothing about the settings. Thanks to a very helpful approach and patient approach, the problem was finally solved. Once again, a big thank you to the great technical team that helps customers.

Ajax stuck around
Having not grown up in the it/ai world, I was daunted with having to use websites, apps and bots. Ajax assisted me very graciously, and didn't disappear when initially this problem proved to be more challenging than originally anticipated. Thank you Ajax team.

Ajax smart decision.
Installed as a replacement for a hard wired system. Ajax designed and installed several sensors and cameras throughout the church building including the roof zone. Ajax smart system allows access to be controlled and off site monitoring is a huge help. Future additions with the potential to add fire monitoring is a great option. After six months we are delighted with Ajax.

The Ajax system replaced and older system and both my wife and I (seniors) find it easy to use. We haven't had a true 'alarm' situation but the system's notifications when we are travelling that trusted friends are in and out of the house is reasuring.
The ability to add more monitoring points easily is a plus.
