## Long description

The Ajax MotionProtect Curtain is a specialized wireless passive infrared (PIR) motion sensor designed to provide precise perimeter protection for indoor environments. By creating a narrow, curtain-like detection zone, this device is engineered to secure specific entry points such as windows, doorways, and corridors. Its sophisticated optical system, consisting of two infrared sensors and a multifaceted mirror, ensures high-accuracy detection while minimizing false alarms, making it an essential component for comprehensive indoor security.
Advantages
This motion detector offers exceptional reliability through its advanced signal processing capabilities, which allow it to distinguish between human movement and the presence of pets. The wireless design ensures a clean and flexible installation process, while the proprietary radio communication protocol provides a secure, encrypted connection to the hub over long distances. With a robust battery life and the ability to operate in varying indoor temperatures, the device maintains consistent performance without frequent maintenance. Its compact, black design allows it to blend discreetly into modern interiors while providing a constant, vigilant watch over your property.
Suitable for
Securing windows and doorways against unauthorized entry
Protecting specific valuables or artwork in museums or galleries
Monitoring garage entrances and perimeter zones
Pet-friendly environments where movement detection is required without triggering false alarms
When it may not be suitable
This sensor is designed specifically for indoor use and is not suitable for outdoor environments exposed to direct weather conditions. It is also not intended for wide-area motion detection, as its narrow beam is optimized for perimeter protection rather than covering large open spaces.

Detection angle: 90°
Sensor type: Passive infrared (PIR)
Connectivity: Wireless
Communication range: Up to 1,700 meters from the hub
Battery life: Up to 3 years

How to use
Installation is straightforward and can be completed in minutes using the Ajax mobile application. Simply scan the QR code provided on the device to register it to your hub, assign it to a specific room, and mount it on the wall using the included bracket. Ensure the sensor is positioned to cover the desired entry point or perimeter area effectively. Once installed, the system will automatically monitor the zone and alert you to any detected movement through the app.
What to consider before purchase
Ensure the device is compatible with your existing Ajax security hub
Verify that the mounting location allows for the narrow beam to cover the intended area
Check that the installation height is appropriate for the desired detection coverage
Confirm that the environment temperature remains within the specified operating range
Usage recommendations
For optimal performance, ensure the sensor is mounted at the recommended height and that the detection zone is not obstructed by furniture, curtains, or other objects. Regularly test the device via the mobile app to ensure connectivity and battery status remain within normal parameters.
