Dahua DHI-ARD1731-W2(868) Wireless PIR-Camera

Dahua DHI-ARD1731-W2(868) Wireless PIR-Camera The Dahua DHI-ARD1731-W2(868) is a wireless PIR motion detector with an integrated 2MP verification camera, designed for use with Dahua wireless alarm systems. When motion is detected, the device captures high-definition images and transmits them to the alarm hub, enabling visual alarm verification and helping users quickly determine whether an alarm event is genuine. This significantly reduces false alarm responses and improves security monitoring efficiency. Combining passive infrared (PIR) detection, built-in infrared illumination, pet immunity, and secure two-way wireless communication, the detector is ideal for residential, commercial, and light industrial intrusion detection applications. Features: Wireless PIR detector with integrated 2MP camera PIR detection range up to 12m with 86° coverage High-resolution image verification up to 1600 × 1200 Captures and transmits alarm snapshots for visual verification Built-in IR illumination for night-time image capture Pet immunity for animals up to 18kg RF-HD image transmission technology Transmission of up to 6 HD images within approximately 10 seconds AES128 encrypted two-way wireless communication Frequency hopping technology for reliable signal stability Three adjustable sensitivity levels Automatic temperature compensation Low battery warning and tamper protection Cloud updates and automatic recovery after update failure Temperature monitoring function Specifications: Product Type: Wireless PIR Detector with Camera Camera Resolution: 2MP Maximum Image Resolution: 1600 × 1200 Detection Technology: Passive Infrared (PIR) Detection Range: 12m Detection Angle: 86° Camera Viewing Angle: 88° Night Vision: IR Illumination up to 12m Pet Immunity: Up to 18kg Sensitivity Levels: 3 Adjustable Levels Wireless Frequency: 868.0–868.6MHz RF-HD Transmission: 2.4GHz Communication Distance: Up to 1,600m (open space) RF-HD Image Distance: Up to 300m (open space) Communication Type: Two-Way Wireless Encryption: AES128 Power Supply: 3 × CR123A Batteries Battery Life: Up to 4 Years (typical usage) Temperature Monitoring: Yes Tamper Protection: Yes Operating Temperature: -10°C to +55°C Dimensions: 127.6 × 71.0 × 53.2mm
