Paradox NV5 / DG55 Dual Element PIR Motion Detector – Pet Immune with 3D Fresnel Lens and Bracket | High-Precision Indoor Security Sensor

The Paradox NV5 / DG55 Dual Element PIR Detector is a next-generation infrared motion detector from Paradox's acclaimed ENVY series. Engineered for superior detection and reliability, this compact yet powerful sensor combines cutting-edge digital optics with user-centric features to ensure premium indoor security for both residential and commercial environments.

At its core, the NV5 utilizes a Hybrid Cylindrical-Spherical 1.0-inch lens embedded with 3rd generation 3D Lodiff® Fresnel segments, a technology that elevates detection accuracy by refining IR energy collection across a wide 10m x 10m coverage area. It delivers uniform sensitivity through its “Equalized” detection pattern, reducing detection gaps and ensuring consistent performance throughout the protected space.

Designed with practicality in mind, this model includes pet immunity up to 16 kg (35 lb)—perfect for pet-friendly homes and businesses. Installation is made effortless with the included mounting bracket, and the detector is enhanced further with Auto Pulse Signal Processing (APSP), offering advanced false alarm rejection and dual/single edge processing options.
