Instant Intrusion Detection for Every Entry Point
Secure your home or office with the AJAX DoorProtect, a sophisticated wireless opening detector designed to be your first line of defense against intrusion. This sleek black device instantly notifies you of the first signs of a break-in through a door or window. It utilizes a high-end, British-made reed switch, tested for over a million openings, to reliably detect when an entry point is breached. Ready to operate straight out of the box with a pre-installed battery, it can be set up in minutes and connected to an Ajax hub with a single click in the mobile app.
Uncompromising Wireless Security
The DoorProtect operates on the proprietary Jeweller radio technology, ensuring a secure and reliable connection to the Ajax hub up to 1,200 meters away in open space. This two-way communication protocol features block encryption and protection against jamming and forgery, making your security system virtually impenetrable. The system regularly checks detector status, with polling periods as frequent as every 12 seconds, to ensure constant protection. With an incredible battery life of up to 7 years, you can enjoy peace of mind without the hassle of frequent battery changes.
Versatile and Tamper-Proof Design
The AJAX DoorProtect is engineered for versatility and resilience. The set includes two different-sized magnets (a small one for gaps up to 1 cm and a large one for up to 2 cm), allowing for flexible installation on various types of doors and windows, including those with metal frames. An integrated tamper alarm will immediately notify you of any attempt to dismantle or detach the detector from its mounting panel. For expanded security, an external terminal is available to connect a third-party wired detector, effectively turning the DoorProtect into a versatile transmitter module.
