Ajax DoorProtect Plus Black | 2-Way Wireless Magnetic Sensor with Shock & Tilt Detection, Jeweller Protocol

Fortify your doors, windows, skylights, and vaults against intrusion with the Ajax DoorProtect Plus Black—a cutting-edge 2-way wireless magnetic opening detector enhanced with shock and tilt sensors for comprehensive protection. Powered by proprietary Jeweller communication technology, this compact device (Ø 20 × 90 mm, 29g) detects the slightest openings via a high-durability reed switch, vibrations from impacts, and tilts beyond 5°-25° thresholds, transmitting instant encrypted alarms up to 1,200m in open spaces. Ideal for indoor use in homes, offices, or commercial properties (-10°C to +40°C), it includes two magnets (small: up to 1cm, big: up to 2cm) for flexible installation on any surface, including metal frames. Connect third-party NC wired detectors for expanded coverage, and enjoy anti-sabotage tamper alerts, frequency hopping against jamming, and block encryption with dynamic keys for unbreakable security. With up to 5 years of battery life on a pre-installed CR123A and remote configuration via Ajax apps (iOS, Android, macOS, Windows), setup is effortless with QR code pairing and SmartBracket mounting. The Chime feature turns it into a shopkeeper's bell for disarmed notifications, ensuring no entry goes unnoticed.
