Advanced Dual-Tech Motion Detector for False Alarm Prevention
The Dahua Dual-Tech Motion Detector ARD2231-W2 (B) is a wireless motion detector combining PIR and microwave sensor technology. This Dahua dual-tech detector avoids false alarms even in challenging environments with active air conditioners and fireplaces. Moreover, it features pet immunity up to 18kg weight and 50cm height, providing reliable security in homes and commercial spaces with pets.
Dual-Technology for Superior Accuracy
This Dahua dual-tech detector combines passive infrared (PIR) and microwave sensing technologies for unmatched detection accuracy. Both sensors must confirm motion before triggering an alarm, virtually eliminating false alarms caused by environmental factors. As a result, you receive alerts only when genuine intrusions occur, reducing unnecessary notifications and maintaining system credibility.
False Alarm Prevention in Challenging Environments
The ARD2231-W2 (B) excels in environments where standard PIR detectors struggle. This Dahua dual-tech detector avoids false alarms from temperature fluctuations caused by air conditioners, heating systems, and fireplaces. The microwave sensor verifies actual movement while the PIR sensor confirms heat signatures. Consequently, it’s perfect for warehouses, offices, server rooms, and spaces with active HVAC systems.
Advanced Pet Immunity Technology
A standout feature of the Dahua dual-tech detector is its comprehensive pet immunity supporting pets up to 18kg weight and 50cm height. This dual-parameter filtering ensures reliable detection while ignoring household pets. Therefore, you maintain security without false alarms from cats, small dogs, and other pets moving through protected areas.
Professional-Grade Detection
The ARD2231-W2 (B) integrates seamlessly with Dahua wireless alarm systems, including ART-ARC3800H series hubs. Designed for indoor installation, the wireless design eliminates complex wiring while dual-tech sensors provide commercial-grade reliability for residential applications.
