Paradox PMD37M Wireless Outdoor / Indoor Curtain Motion Detector with Anti-Masking

The Paradox PMD37M (PMD37) is an official high-precision 2-way wireless dual-optic curtain motion detector engineered for the Paradox M Series security ecosystem. Designed for both indoor and outdoor applications, it projects a narrow, wall-hugging curtain coverage beam (0.5 m X 12 m / 1.6 ft X 40 ft), making it ideal for protecting glass sliding doors, window perimeters, corridors, and exterior building walls. Equipped with active infrared anti-masking technology, it immediately detects attempts to blind or block the lens with spray paint, tape, or objects.

Key System Features & Functionality

• Narrow Curtain Detection Beam: Projects an ultra-narrow 0.5m wide curtain pattern up to 12 meters to secure perimeters without triggering on indoor movement behind the plane.

• Active Infrared Anti-Masking: Detects degradation of optical clarity, spray paint, tape, or paper placed over the lens within 30cm.

• IP54 Weatherproof Enclosure: UV-protected, water-resistant housing with rubber seals designed for indoor and covered outdoor wall installations.

• Encrypted GFSK 2-Way RF: Operates over secure 2-way wireless frequencies (868 MHz or 914 MHz) with frequency and encryption hopping for maximum transmission reliability.

• Pet Immunity Support: Advanced optical beam filtering ignores small domestic animals moving beneath or parallel to the curtain plane.

• Dual Anti-Tamper System: Protects against unauthorized opening of the detector enclosure or detachment from the wall mounting bracket.
