Dahua DHI-ARD2631E-W2, Wireless External Curtain PIR

*Special Order Item*

The Wireless External Curtain PIR is a motion detector that uses dual motion sensing technology. Its narrow 8° horizontal curtain beam reaches up to 12 meters, providing focused perimeter coverage and reliable intrusion detection. Suited for indoor and outdoor use, it helps protect windows, doorways and other access points.

Features:

• Dual PIR + Microwave.
• Supports installation at both high and low heights.
• Supports detection distance adjustment.
• Supports microwave trajectory tracking. By capturing the target's three-dimensional information (distance, velocity, and angle), it establishes a moving trajectory map that can identifies target motion patterns, filters out non-target movement interference, and reduces false alarm rates.
• Supports anti-masking.
• OTA upgrading.
• IP65 rated.
• Supports back-to-back installation of two detectors, forming left and right bidirectional detection zones to achieve full coverage protection of passageways on both sides of doors and windows.
