Ajax security system
I have had the Ajax security system fitted to my home for 6 months, no problems. Easy to use. The installation was trouble free. Very pleased with the security system

I am happy with Ajax but not with the Turkey representetive
I am generally happy with Ajax products, but unfortunately my experience with Kaly Bilişim in Turkey has been extremely disappointing. They are completely unresponsive — they do not reply to emails or whatsapp. I was sold a defective product and, despite the fact that it is still under warranty, I have not received the support I need.
I have also contacted Ajax directly by email because I am currently dealing with a genuine home security issue, and I urgently need this matter resolved. I am now waiting for Ajax to respond and take action as soon as possible.
If the issue is not resolved, I will update this review accordingly.

Excellent system and outstanding customer support
I’ve been using the Ajax security system with several different devices, including sensors, HomeSiren, DoorBell and Relay, and I’m extremely impressed with the whole ecosystem.
The products are well designed, reliable, easy to configure and offer a huge amount of flexibility when building or expanding a security and smart-home setup.
What impressed me most, however, is the customer support. I honestly don’t remember ever experiencing support this good from a technology company. Fast responses, knowledgeable people who actually understand the products, and a genuine effort to investigate and solve the problem rather than just sending generic instructions.
The combination of excellent hardware, a very polished app and exceptional support makes Ajax an easy 5/5 recommendation for me.
