## Summary description

The Ajax MotionProtect Curtain is a wireless passive infrared (PIR) motion sensor designed for precise perimeter protection. It features a narrow detection angle, making it ideal for securing windows, doorways, and specific zones within a building. The device includes a mounting bracket for easy installation and integrates seamlessly into the Ajax security ecosystem to provide reliable intrusion detection.

## Long description

The Ajax MotionProtect Curtain is a specialized wireless passive infrared (PIR) motion sensor engineered for precise perimeter security. By utilizing a narrow detection beam, this device creates an invisible barrier that effectively monitors windows, doorways, and specific entry points within a building. It integrates seamlessly into the Ajax security ecosystem, ensuring that any unauthorized movement is detected instantly while maintaining a reliable connection to the central hub.
Advantages
This sensor utilizes advanced proprietary optical technology, combining two infrared sensors with a multifaceted mirror to capture detailed information about the protected area. This design ensures a rapid and accurate reaction to human presence, regardless of whether an intruder is moving quickly or attempting to sneak past. The device is built for longevity and reliability, offering a battery life of up to three years and robust radio communication that remains stable even at distances of up to 1,700 meters from the hub. Furthermore, the system is designed to be pet-friendly, allowing for secure perimeter monitoring without triggering false alarms from household animals when installed according to the manufacturer's guidelines.
Suitable for
Securing windows and doorways against unauthorized entry
Protecting specific zones or valuables within a home or museum
Monitoring garage entrances in varying temperature conditions
Creating a secure perimeter while allowing movement within other areas of the building
When it may not be suitable
The MotionProtect Curtain is designed for narrow, focused detection and is not intended for monitoring large, open-plan rooms where wide-area coverage is required. It may also be less effective if the mounting location is obstructed by furniture or other objects that block the narrow infrared beam.

How to use
Installation is designed to be quick and straightforward. Begin by using the Ajax mobile application to scan the QR code on the device to add it to your security system. Once registered, mount the sensor on the wall using the included bracket, ensuring it is positioned to cover the desired window or doorway. The narrow beam should be directed across the path an intruder would take to enter the protected zone.
What to consider before purchase
Ensure your existing security system is compatible with Ajax devices
Verify that the mounting surface is stable and allows for the correct beam orientation
Check that the installation height is appropriate for the specific area to ensure optimal pet immunity
Usage recommendations
For the best performance, ensure the sensor is not pointed directly at heat sources or moving objects that could cause false triggers. Regularly test the device through the Ajax app to confirm signal strength and battery status.
