Dahua ARD2251E-W2(868), Wireless Outdoor PIR Detector 15m, Anti-mask, Pet Friendly, AirShield, IP66

The wireless Triple-Tech detector performs accurate detection using PIR, microwave detection technology, optical technology and intelligent algorithms. It also eliminates interference caused by small animals, ambient temperature and changes in light, so that the detector accurately recognizes moving people even in complex environments. Combined with the camera module, the possibilities expand, allowing scenes to be monitored via videos and images, and alarms to be checked in real time. Notifications are also sent when alarms are triggered, so that you can stay informed of the situation at your location.
