Paradox NV37MR-PHY Outdoor/Indoor Wireless Curtain PIR Motion Detector with Anti-Masking & Pet Immunity

The Paradox NV37MR-PHY is a premium wireless outdoor and indoor curtain PIR motion detector engineered to secure perimeter boundaries such as windows, sliding glass doors, balconies, and patio entryways. Operating on dual selectable wireless frequencies (433 MHz or 868 MHz), it delivers narrow-beam curtain detection designed to identify intruders before they gain access to the interior, while permitting normal human movement inside the protected area.

Built for harsh environmental conditions, the NV37MR features an IP54 weather-resistant casing and advanced Active IR Anti-Masking technology that detects attempts to blind or cover the lens with spray paint, foil, or physical obstacles. Equipped with Paradox's optical Mirror architecture and dual-element PIR sensors, it offers exceptional immunity against small animals (Pet Immunity mode) and outdoor environmental disturbances like wind and foliage movement. This variant requires two standard 1.5V AA Alkaline batteries (not included).

Key System Features & Functionality

• Narrow Curtain Coverage: Provides precise, narrow beam detection (7.5m x 2m / 25ft x 7ft in Pet Immunity mode; 10m x 2m / 33ft x 7ft in Sharp/Indoor mode) ideal for window and door protection.

• Active IR Anti-Masking: Detects attempts to block or obscure the detector's optical lens with liquids, sprays, or physical objects, triggering an immediate sabotage alert.

• Pet Immunity & Environmental Filtering: Advanced optical geometry filters out pets up to 50 cm (20 in), preventing false alarms caused by birds, small domestic animals, or swaying leaves.

• Selectable Dual RF Frequency: Supports both 433 MHz and 868 MHz wireless transmission frequencies for versatile integration with Paradox Magellan wireless systems and RTX3 expansion receivers.

• IP54 Weather-Proof Housing: Ruggedized, UV-resistant gasket-sealed enclosure engineered to withstand rain, dust, and temperature extremes (-35°C to 50°C).

• Dual Tamper Protection: Features integrated wall and cover tamper switches that immediately report physical removal or opening of the housing to the main alarm panel.
