Curtain PIR Detector NV37M-P2C

With a super-narrow detection beam of just 0.5 m at 5 m, the NV37M-P2C curtain PIR detector creates an invisible infrared barrier up to 10 m long, ideal for protecting windows, doors, and perimeters with surgical precision.

Overview

The NV37M-P2C is a wired outdoor/indoor curtain PIR detector engineered for demanding security installations. It employs a custom-designed super-narrow beam lens and advanced digital signal processing (ADSP) to deliver reliable detection while minimizing false alarms. The dual optical filtering system further enhances immunity to white light and other environmental disturbances.

What stands out

• Super-narrow curtain detection pattern: beam width only 0.5 m at 5 m distance, perfect for perimeter protection.
• Active IR anti-masking detects attempts to cover or block the sensor.
• Dual tamper protection (cover and wall) ensures immediate alarm on any tampering.
• Pet immunity up to 50 cm height, allowing small animals to move freely without triggering alarms.
• Five-level sensitivity adjustment for fine-tuning to the installation environment.
• Robust IP54-rated housing for outdoor use, with operating temperature range from -35°C to 60°C.
