## Long description

The Ajax DoorProtect Plus is a professional wireless sensor engineered to provide comprehensive security for doors and windows. This device utilizes advanced RF wireless technology to monitor entry points, ensuring reliable perimeter protection for both residential and commercial alarm systems.
