Dahua Airshield ARD1233-W2 Wireless PIR Sensor, 90°, up to 12m, PET immunity up to 18kg

Dahua Airshield ARD1233-W2 — Wireless PIR Detector with Pet Immunity

Securing homes and commercial spaces requires reliable solutions that minimize the risk of false alarms. The Dahua Airshield ARD1233-W2 offers motion detection up to a distance of 12 meters with a 90° field of view, making it ideal for monitoring entry doors or critical areas. Thanks to its immunity to pets weighing up to 18 kg, the device prevents unwanted alarm triggers. With Security Grade 2 certification (EN 50131 standard), it is also suitable for professional installations.

Technology and Precise Detection

The detector utilizes a dual low-noise PIR sensor, ensuring reliable motion detection for movement speeds ranging from 0.3 to 3 m/s. Automatic temperature compensation maintains consistent performance even at high temperatures—up to +55 °C —making it suitable for various climatic conditions. With resistance to white light interference of up to 2000 lx, the device is less susceptible to malfunctions caused by ambient lighting.

Wireless Communication and Security

The detector communicates via the 868.0-868.6 MHz frequency band, featuring two-way data transmission and frequency hopping technology. This ensures a stable connection over distances of up to 1600 meters in open-field environments. AES128 encryption protects transmitted data from unauthorized access, enhancing the overall security of the system. An automatic low-battery detection feature—utilizing a CR123A battery with a lifespan of up to 4 years —simplifies maintenance.

Installation and Design

With compact dimensions of 104 × 60 × 50 mm and a weight of just 100 g, installation is simple and discreet. The enclosure, made of PC + ABS materials, provides basic corrosion protection, allowing for use in indoor environments with humidity levels of up to 90% RH. A test mode and a green LED indicator facilitate device setup and functional verification. ### Product Specifications
