The Ajax Wireless Home Security Alarm Starter Kit – 4 Room is designed to provide smart, reliable protection for medium-sized homes and offices. This easy-to-use alarm kit ensures your family or property is always protected, without the hassle of complicated installation. All devices work wirelessly and connect to the central Ajax Hub 2 (4G), which immediately sends alerts to your smartphone whenever something unusual is detected.
How It Works
Once set up, the system continuously monitors movement and entry points around your property. If unexpected motion is detected or a door or window is opened, the internal and external sirens activate instantly, while a real-time notification is sent to your smartphone via the Ajax app. The Hub connects through Ethernet to ensure stable and uninterrupted communication.
Hub 2 Control as Standard
Every Ajax alarm kit we supply includes the Hub 2 Control Unit as standard. This advanced hub supports image verification through MotionCam detectors, so your system is already compatible for future upgrades. There’s no need to change the hub later — simply add MotionCam devices whenever you want enhanced image-based alerts.
