## Long description

The Ajax DoorProtect Plus is a sophisticated wireless sensor engineered to monitor the opening of doors and windows, providing a robust layer of security for residential and commercial environments. This device utilizes high-end reed switches to detect magnetic field changes, ensuring precise notification of unauthorized entry. Beyond standard opening detection, the sensor features an integrated accelerometer capable of identifying vibrations, impacts, and changes in the vertical tilt angle, making it an ideal solution for securing roof windows that may be left slightly ajar for ventilation.
Advantages
The primary benefit of the Ajax DoorProtect Plus is its versatility in security monitoring, as it goes beyond simple contact detection to include vibration and tilt sensing. This allows users to secure windows even while they are in a ventilation position, offering peace of mind without compromising airflow. The device is designed for rapid deployment, arriving with a pre-installed battery and a user-friendly mounting system that requires minimal effort to set up. Its seamless integration into the Ajax security ecosystem ensures reliable communication with the hub, while the long-lasting battery life significantly reduces the need for frequent maintenance.
