AJAX MotionProtect Curtain (Jeweller) – Wireless Narrow-Angle Curtain Motion Detector (White)

Product Overview

The Ajax MotionProtect Curtain  is a wireless narrow-beam indoor motion detector engineered to establish an invisible perimeter curtain across doors, windows, patio entries, and valuable assets. Utilizing two independent passive infrared (PIR) sensors paired with a multi-faceted optical lens, it produces a narrow 6° horizontal detection barrier extending up to 15 meters (49.2 ft).

Operating via the proprietary Jeweller wireless radio protocol across distances up to 1,700 meters in open space, MotionProtect Curtain allows occupants and pets to move freely within a room without triggering false alarms, while immediately detecting any boundary breach in less than 0.15 seconds. Equipped with proprietary ELST (Extended Live Signal Track) digital signal correlation to filter thermal noise, directional intrusion verification, Grade 2 anti-tamper security, and a pre-installed CR123A battery delivering up to 3 years of autonomous service, it provides precise indoor perimeter security in a clean white housing.

Key System Features & Functionality

• Narrow-Angle Perimeter Curtain: Creates a focused 6° horizontal beam barrier up to 15 meters long to secure entryways without restricting indoor room movement.

• Dual PIR Sensor Correlation: Dual optical sensors and advanced digital signal filtering prevent false alarms from draft airflow, curtain flutter, and pets walking beneath the beam.

• Directional Intrusion Detection: Configurable to trigger alarms either in bidirectional mode or only when movement is detected entering from an exterior boundary.

• Jeweller Wireless Technology: Two-way encrypted radio communication operating up to 1,700 meters (5,570 ft) line-of-sight with anti-jamming frequency hopping.

• Up to 3 Years Battery Life: Powered by a pre-installed CR123A lithium battery with intelligent power-saving algorithms.

• Versatile Mounting Hardware: Installs on flat walls, window jambs, or corners using the included SmartBracket and angle mounting bracket.
