Dahua Speed Dome PTZ IP positioning system with 25x zoom and AI WizSense – video surveillance camera PTZ1A225-HNR-XA is equipped with neural network processor. It supports WizSense intelligent functions to effectively improve the detection accuracy and people, motor vehicle and non-motor vehicle image capture plus perimeter protection. The device can detect motor vehicles, non-motor vehicles, human faces and human bodies. The camera automatically filters out false alarms caused by animals, rustling leaves, bright lights, etc. and enables system to act secondary recognition for the targets to improve alarm accuracy.
 
Dahua PTZ1A225-HNR-XA supports 6 attributes and 8 expressions, face enhancement, and attributes extraction. For challenging low-light applications, Dahua Starlight Ultra-low Light Technology offers best-in-class light sensitivity, capturing color details in low light down to 0.005 Lux. The camera uses a set of optical features to balance light throughout the scene, resulting in clear images in dark environments. PFA technology has innovatively introduced new methods of judgment to ensure the accuracy and predictability of the direction of subject distance adjustment. The result is a set of advanced focusing algorithms. PFA ensures clarity of the image throughout the process of zooming and shortens focus time. The realization of PFA technology substantially improves user experience and increases product value. This feature controls the pan/tilt/zoom actions of the camera to automatically track an object in motion and to keep it in the scene. The tracking action can be triggered manually or automatically by defined rules. Once a rule is triggered, the camera can zoom in and track the defined target automatically.
