DHI-ARD2631E-W2 Wireless External Curtain PIR Motion Detector - 433 MHz
The Dahua DHI-ARD2631E-W2 is a wireless external curtain PIR motion detector designed for focused intrusion detection around narrow access points. It combines dual PIR sensing with 24 GHz microwave detection, offering an adjustable 5-12 m detection range and a narrow 8° horizontal curtain pattern. Anti-masking, microwave trajectory tracking and tamper detection provide additional protection against interference and unwanted movement.
Designed for indoor or outdoor wall mounting, its IP65-rated housing suits doorways, windows and passageways. The detector supports low mounting from 0.8-1.3 m or high mounting from 2-2.4 m, while pet immunity accommodates animals under 60 cm tall and approximately 18 kg when installed at 2.4 m. It operates across the 433.05-434.79 MHz band and is powered by two CR123A batteries.
