Dahua PTZ-DH-SD49225XA-HNR 2MP 25X OPTICAL ZOOM WDR IP66 PTZ CAMERA 100METER

Featuring powerful optical zoom and accurate pan/tilt/zoom performance, this camera provides an all-in-one solution for capturing long
distance video surveillance for outdoor applications. Together with
infrared illumination and Starlight Technology, the camera is the perfect
solution for dark, lowlight applications. The series combines a day/night
mechanical IR cut filter for the highest image quality in variable lighting
conditions during the day, and True WDR for applications with direct
sunlight or glare.
Functions
Perimeter Protection
Automatically filters out false alarms caused by animals, rustling leaves,
bright lights, etc. Enables system to act secondary recognition for the
targets to improve alarm accuracy.
Starlight+ Technology
For challenging low-light applications, Dahua’s 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
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.
SMD PLUS
With Deep-Learning Algorithm, Dahua SMD PLUS filters the motion
detection alarm triggered by non-concerned target and recognizes human and vehicle effectively, sending alarms when human and vehicles
intrude.
Wide Dynamic Range
The camera achieves vivid images, even in the most intense contrast
lighting conditions, using industry-leading wide dynamic range (WDR)
technology. For applications with both bright and low lighting conditions
that change quickly, True WDR (120 dB) optimizes both the bright and
dark areas of a scene at the same time to provide usable video.
Auto-tracking
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.
Smart H.265+
Smart H.265+ is the optimized implementation of the H.265 codec that
uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI,
flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network. Smart
H.265+ technology reduces bit rate and storage requirements by up to
70% when compared to standard H.265 video compression.
