## Summary description

Ajax MotionProtect Curtain Black is a curtain‑style motion detector designed for targeted perimeter protection. It uses a PIR sensor in a compact black housing to detect movement along a narrow, curtain‑like beam. Suitable for doorways, windows and corridors, it reduces false alarms and provides discreet detection for residential and commercial installations.

## Long description

MotionProtect Curtain Black is a curtain‑style PIR motion detector in a compact black housing designed for targeted perimeter protection of windows, doors, balconies and narrow access paths. The sensor forms a narrow invisible beam up to 11 meters long, works indoors and outdoors, and is intended to detect intruders while ignoring small animals and common environmental disturbances.
Advantages
The detector uses two PIR sensors and an intelligent ZOE algorithm to compare signals and distinguish humans from pets and birds, reducing false alarms. The device is rated IP54 for dust and water resistance, features an always‑active anti‑masking system and tamper protection, notifies the system within 0.15 seconds, and provides up to three years of battery life on a CR123A cell. Setup is performed via QR code in the Ajax app and requires only a few minutes.
Suitable for
Perimeter protection for yards, fences and facades
Securing doors, windows, terraces and balconies
Monitoring narrow indoor access routes, corridors and shopfronts
Protecting display items in museums or galleries
Apartment entrances on ground and top floors

How to use
Install MotionProtect Curtain on the facade, fence, window frame or indoors at the recommended height (about 2.4 m) so the narrow detection curtain covers the access path to be protected. Configure sensitivity and pet‑immunity in the Ajax app according to the installation environment, then add the detector to the Hub by scanning the QR code and following the app prompts. The detector can be mounted horizontally, upside down or at an angle; perform remote testing from the app after mounting to confirm coverage and adjust orientation if necessary.
Usage recommendations
For reliable operation, avoid placing the detector opposite large heat sources or reflective glass surfaces and keep the sensing axis aligned with the protected passage. Enable pet‑immunity when animals under 15 kg or 40 cm are present. Check the IP54 rating when installing in exposed outdoor locations and perform periodic battery and tamper checks through the Ajax app.
