Ajax DoorProtect (Door & Window Contact)

---

The Door & Window Sensor is a wireless opening detector that alerts your system whenever a protected door or window is opened. It's one of the simplest and most effective ways to secure common entry points into a home or business.

Door & Window Sensors are commonly installed on entry doors and accessible windows to detect unauthorized opening. They're ideal for homes, businesses, offices, storage rooms, and other areas where monitoring an entry point is important.
