Paradox NV37M-P2C Indoor/Outdoor Narrow Curtain PIR Detector with Active Anti-Masking

The Paradox NV37M-P2C is an advanced, high-performance indoor/outdoor narrow curtain motion detector engineered specifically for perimeter protection of windows, patio doors, and sliding glass entry points. Utilizing two dual-element passive infrared (PIR) sensors managed by Full Authority Digital Electronics Control (FADEC), the NV37M-P2C generates a precise, solid boundary beam (0.5m width at 5m distance). This design creates an invisible security barrier that allows occupants to move freely near protected entryways without triggering false alarms.

Designed for extreme environmental conditions and high-security requirements, the NV37M-P2C features active infrared anti-masking technology with a dedicated processing chip. It reliably detects sprayed liquids or physical objects obstructing the lens up to 30 cm away. Equipped with Paradox's Super Pet Immunity geometry, it suppresses false triggers caused by small animals, birds, and pets. The detector offers dual operational modes—Outdoor Pet Immune Mode (up to 7.5m x 2m) and Indoor Sharp Mode (up to 10m x 2m)—making it an ideal choice for residential, commercial, and industrial perimeter monitoring.

Key System Features & Functionality

• Narrow Curtain Protection: Delivers a highly focused 0.5m x 5m curtain pattern to protect window frames and door openings without disrupting internal room movement.

• Active IR Anti-Masking: Advanced active infrared detection identifies sprayed liquids, clear lacquers, and physical obstructions within 30 cm of the lens.

• Dual Operating Modes: Easily configurable between Outdoor Pet Immune Mode (7.5m x 2m) and Indoor Sharp Mode (10m x 2m) with enhanced range and sensitivity.

• Super Pet Immunity: Features optical geometry specifically tuned to discriminate against birds, small dogs, and cats to drastically eliminate false alarms.

• FADEC Digital Signal Processing: Powered by Full Authority Digital Electronics Control to ensure optimum signal analysis and environmental noise rejection.

• Weatherproof & Dual Tamper: IP54-rated housing built for extreme weather conditions (-35°C to 60°C) with dual cover and wall tamper protection.
