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

Product Overview

The Ajax MotionProtect Curtain is a specialized indoor curtain-type wireless motion detector designed to create an invisible narrow perimeter barrier across windows, doorways, patio sliders, and valuable artwork. Utilizing dual PIR sensors with opposing detection patterns and a precision faceted lens, it creates a tight detection curtain with a narrow 6° horizontal viewing angle and a range of up to 15 meters (49.2 ft).

Operating via the proprietary Jeweller wireless radio protocol across open-space distances up to 1,700 meters, MotionProtect Curtain allows occupants and pets to move freely inside the room while triggering an alarm the instant an intruder crosses the boundary line. Equipped with proprietary ELST (Extended Live Signal Track) digital signal processing to eliminate false thermal alarms, Grade 2 anti-tamper security, and a pre-installed CR123A battery delivering up to 3 years of autonomous operation, it delivers targeted perimeter security in a sleek matte black casing.

Key System Features & Functionality

• Narrow-Angle Curtain Protection: Forms a focused 6° horizontal detection barrier up to 15 meters long, enabling internal perimeter protection while occupants freely move indoors.

• Dual PIR Sensors & Correlation Analysis: Employs two independent PIR sensors and digital signal processing to filter out false alarms from air currents, curtains moving, or pets walking beneath the beam.

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

• Directional Movement Detection: Configurable to trigger alarms either in both directions or exclusively when entering from the outside.

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

• Flexible Mounting Options: Installs directly on walls, window frames, or in corners using the bundled SmartBracket and angle mounting bracket.
