Dahua Airshield ARD1731-W2 Wireless PIR Sensor (86° FOV, up to 12m range, 18kg pet immunity) + 2MP Camera (88° FOV, 12m IR range)

Dahua Airshield ARD1731-W2 — PIR Sensor with Camera

Securing a home or office requires a precise, reliable solution that combines motion detection with visual verification. The wireless Dahua Airshield ARD1731-W2 PIR sensor, featuring an integrated 2MP camera, captures images upon detecting an intrusion and instantly transmits them to a mobile app or monitoring station. With an IR illumination range of 12 m and a detection range of 12 m at an 86° angle, it is ideal for covering large areas, even in low-light conditions. Additionally, the sensor offers pet immunity for animals up to 18 kg, minimizing false alarms.

Combining Motion Detection and Visual Verification

The integrated camera, equipped with a 2MP CMOS sensor, captures detailed images at resolutions up to 1600 × 1200 px, enabling accurate visual alarm verification. Images are transmitted using advanced 2.4GHz RF-HD technology, ensuring fast and secure data transfer. Thanks to automatic temperature compensation, the detector remains reliable even in environments with fluctuating temperatures.

Flexible Wireless Connectivity

The device supports two wireless transmission modes: RF 868 MHz with a range of up to 1600 m and 2.4 GHz Wi-Fi for easy integration into existing networks. Transmitted data is protected by AES128 encryption, ensuring security during transmission.

Advanced features and high energy efficiency

With a detection speed of 0.3-3 m/s, the sensor can capture even rapid movements. Thanks to optimized power consumption and a quiescent current of just 65 µA, the device can operate for up to 4 years on three CR123A batteries. An early low-battery warning feature ensures trouble-free operation.
