Uncompromised, Multi-Layered Entry Protection
Secure your property with the AJAX DoorProtect Plus, a next-generation wireless detector that offers three layers of security for any door or window. This device instantly detects opening, vibration, and changes in tilt, providing immediate notification of the first signs of an intrusion. It protects your home even when windows are left open for ventilation, thanks to its advanced accelerometer that registers changes in vertical slope, bangs, and any vibration, sending an instant alarm to the hub. Ready to operate straight out of the box, the battery is pre-installed for an effortless setup that takes just minutes.
Core Features of the DoorProtect Plus:
- Triple-Sensor Detection: Combines a high-end magnetic opening contact (reed switch) with a sensitive shock and tilt sensor (accelerometer) to guard against various intrusion methods.
- Advanced Accelerometer: Registers vibrations, impacts, and changes in vertical slope angle greater than 5°, making it ideal for protecting windows left open for ventilation.
- Jeweller® Wireless Technology: Ensures secure, long-range communication with the Ajax hub up to 1,200 meters in open space. The encrypted, two-way communication prevents jamming and device forgery.
- Exceptional Battery Life: Operates for up to 5 years on the pre-installed CR123A battery, minimizing maintenance and ensuring long-term reliability.
- External Detector Input: Features an external contact for connecting third-party wired detectors, allowing you to easily expand your security system's coverage.
- Effortless Installation: No need to disassemble the detector. It connects to the hub with a single click in the Ajax mobile app and mounts in minutes using the included SmartBracket.
