Dahua DHI-ARD2231-W2 Wireless Dual-Tech Detector
The Dahua DHI-ARD2231-W2 is an intelligent wireless motion detector that combines PIR and microwave sensing, requiring both technologies to trigger for far fewer false alarms in challenging environments. With pet immunity, automatic temperature compensation and 3-level sensitivity, it pairs with Dahua wireless alarm hubs (ARC series) and is managed in the DMSS app for reliable residential and commercial protection.
PIR + Microwave
Dual detection requires both sensors to confirm motion, dramatically reducing false alarms.
Pet Immunity
Ignores small pets while still detecting people moving through the protected area.
Temperature Compensation
Auto temperature compensation keeps detection stable as ambient conditions change.
Secure Two-Way RF
Frequency hopping, anti-jamming and AES128 data encryption keep communication stable.
