Overview
Ajax Systems is a Ukrainian company founded in 2011 that designs and manufactures wireless security and smart home systems, and it has become the largest such manufacturer in Europe. Its products cover intrusion detection, fire and flood sensors, cameras, access control and automation devices, sold through professional installers rather than retail, on the argument that security systems should be specified by someone who will also maintain them. Headquartered in Kyiv with manufacturing in Ukraine and Turkey, it continued expanding through the war and now sells across more than a hundred and eighty countries.

Products
Ajax Cloud and Apps
The cloud service and applications through which users and installers manage systems. Installers monitor hundreds of client sites through it, which makes their workflow as important a design consideration as the end user's.
ajax.systems
Access Control
Readers, keypads and credential management for doors and gates. Extending into access control lets an installer serve a small commercial site entirely from one product family rather than combining vendors.
ajax.systems
Video Surveillance
Cameras and video recording connected to the same hub and application. Video verification lets a monitoring station confirm an alarm before dispatching a response, which sharply reduces false call-outs.
ajax.systems
Fire and Flood Detection
Smoke, heat and leak detectors integrated into the same system as the security devices. Combining life safety with intrusion detection means one installation and one app rather than two unrelated systems.
ajax.systems
Intrusion Detection
Wireless alarm panels, motion detectors and door sensors for homes and businesses. Wireless installation avoids the cabling that made professional alarm systems expensive to retrofit into existing buildings.
